MEGA Review 2026: 20GB Free, Real Encryption, Real Baggage

MEGA is the cloud storage nobody talks about in polite company and everyone uses anyway. It has the biggest free tier of any zero-knowledge encrypted provider (20GB), a legitimate client-side encryption architecture, native Linux support that its competitors refuse to build, and a founder whose name still scares enterprise buyers twelve years after he left the company. It also carries real baggage: a 2022 cryptographic attack paper from ETH Zurich that exposed legacy architecture debt, a bandwidth cap that can lock free users out for hours, and a piracy reputation that gets legitimate accounts swept up in automated bans.

We've used MEGA as a secondary cloud for about three years and just finished a fresh round of testing in early 2026. This review is what we actually found, including the parts the MEGA marketing team would rather we left out.

What does MEGA actually cost in 2026?

MEGA is based in New Zealand and prices its plans in euros, then converts to USD at checkout.

The paid tiers, rounded to USD:

• Pro Lite: 400GB storage, 1TB monthly transfer, about $5.67/month
• Pro I: 2TB storage, 2TB monthly transfer, about $11.36/month
• Pro II: 8TB storage, 8TB monthly transfer, about $22.73/month
• Pro III: 16TB storage, 16TB monthly transfer, about $34.10/month
• Business: starts with a 3-user minimum and flexible storage, around $17-18/month base with additional-TB add-ons

One detail most reviewers miss: MEGA's paid plans include monthly transfer quota equal to storage quota. A Pro I 2TB plan gives you 2TB of outbound transfer per month, Pro II gives you 8TB, and so on. That's unusually generous compared to unlimited plans that throttle after heavy use, and it's the feature that makes MEGA practical for sharing large files with a lot of recipients.

The free tier is the other headline number. MEGA gives new accounts 20GB permanent free storage, which is the largest free tier of any zero-knowledge encrypted provider on the market. Sync.com gives 5GB, pCloud gives 10GB (but charges extra for encryption), Proton Drive gives 5GB free. MEGA's 20GB is a real differentiator for anyone testing the product or using it as secondary storage.

There used to be a stacking "Achievements" system that let you earn extra storage by installing the desktop app, verifying a phone number, and inviting friends. MEGA scaled this back. Bonuses from achievements are now mostly time-limited (365 days or less) and revert after expiration. Older reviews still quote "up to 50GB free" based on stacked achievements. That's not the current reality. Plan for 20GB.

How fast is MEGA in real-world testing?

MEGA's speeds are better than most people expect, with an important caveat about free-tier bandwidth caps.

On a paid Pro I account with a 400 Mbps cable connection, we saw sustained upload speeds around 90 Mbps and download speeds around 125 Mbps on a 1GB test file. That's solid for a client-side encrypted service. Cloudwards' 2025-2026 benchmark ranked MEGA at the top of their speed testing for paid tiers, with stable throughput and minimal CPU overhead during transfers. MEGA is in the same speed tier as pCloud and noticeably faster than Sync.com, which is a meaningful advantage given that both MEGA and Sync.com encrypt client-side.

The trade-off shows up on gigabit connections. MEGA's transfer infrastructure doesn't scale to saturate a 1 Gbps line the way pCloud can. On our gigabit test line, upload speeds topped out around 150 Mbps and downloads around 220 Mbps. Still good. Not class-leading.

The free tier has a bandwidth cap that will ruin your day if you don't know about it. MEGA enforces an IP-based transfer quota on free accounts, roughly 5GB per rolling 6-hour window, though MEGA has never published the exact numbers and they vary by region and load. When you hit the cap, downloads stop. You see a "Bandwidth limit exceeded" error. Logging out and back in does not reset it, because the cap is tied to your IP address, not your account. The only fix is waiting about six hours for the rolling window to reset, or using a VPN to change your IP, or upgrading to a Pro plan.

This affects two groups: heavy free users, obviously, and anyone downloading a large shared file from someone else's MEGA account, because the cap applies to the downloader's IP on free-tier links. It's the single biggest source of user frustration with MEGA free and it's not going away.

Is MEGA's encryption actually zero-knowledge?

Yes, with caveats that matter.

MEGA encrypts every file client-side with AES-128 before upload. Keys are derived from your password, wrapped with a master key, and stored server-side only in encrypted form. MEGA's servers never see your plaintext files or your master key under the normal authentication flow. Shared folders and files use RSA-2048 to wrap file keys for recipients. End-to-end encryption applies to every tier, including free, which is rare.

Then there's the 2022 ETH Zurich paper. In June 2022, three cryptography researchers (Matilda Backendal, Miro Haller, and Kenneth Paterson) at ETH Zurich's Applied Cryptography Group published "Mega: Malleable Encryption Goes Awry," disclosing five attacks against MEGA's cryptosystem. The attacks ranged from RSA key recovery (requiring about 512 authenticated logins to extract a user's private key) to a framing attack that could inject malicious files into a user's account to a Bleichenbacher-style attack on RSA encryption.

MEGA was notified under responsible disclosure on March 24, 2022, acknowledged the findings, paid a bug bounty, and released patches on June 21, 2022. The patches directly addressed three of the five issues and added integrity checks that block the practical exploitation path of the key recovery attack. The researchers noted that a complete fix would require phasing out legacy key material and re-encrypting all existing user files, which MEGA said would take multiple years.

Where does that leave security in 2026? MEGA's current architecture is substantially patched against the specific attacks disclosed in 2022, and no new cryptographic break has been published since. The underlying legacy debt is real but theoretical for individual users; practical exploitation would require either a malicious MEGA insider or a very specific server compromise scenario. Cloudwards and ProPrivacy both now describe MEGA as "no longer purely zero-knowledge in the strictest sense" while also acknowledging that it remains materially stronger than Google Drive, OneDrive, or iCloud without Advanced Data Protection.

Our honest take: MEGA is fine for personal files where your threat model is "I don't want a cloud provider's ad team reading my photos" or "I want my backups encrypted from my ISP and random data breaches." MEGA is not the right choice for files where your threat model is "a nation-state actor is actively targeting me specifically." For that threat model, Proton Drive, Tresorit, or Sync.com have cleaner architectures.

Security Analysis

Beyond the encryption specifics, MEGA's broader security posture has a few things worth knowing.

Password reset equals permanent data loss. Like every zero-knowledge provider, MEGA cannot reset your password because they don't have your encryption keys. If you lose your password and didn't save a recovery key, your files are unrecoverable. MEGA offers a recovery key you can save at signup. Most people never save it. Most people don't realize the consequences until it's too late. Save your recovery key the day you sign up, store it somewhere physical, and don't rely on MEGA to bail you out if you forget your password.

New Zealand jurisdiction. MEGA is incorporated and operated in Auckland, New Zealand, which puts it outside the core Five Eyes data-sharing relationship in terms of routine cooperation (though New Zealand is a Five Eyes member). For most practical purposes, this is a mild positive on the privacy side, and MEGA has no transparency report comparable to Apple's. The absence of a transparency report is worth flagging as a criticism.

Third-party audits are missing. MEGA has not published a recent full independent cryptographic audit of its post-2022 patched architecture. The 2022 ETH Zurich paper is the most recent substantive external analysis. For a product whose main selling point is encryption, we'd like to see a current Cure53 or similar audit. We don't have one.

Kim Dotcom no longer owns MEGA

This comes up in every MEGA discussion and the facts are simpler than the conspiracy theories suggest.

Kim Dotcom founded MEGA in January 2013, exactly one year after the US Department of Justice shut down his previous file-hosting company, Megaupload. Dotcom was the public face of the launch. He was never the sole owner. He resigned as a director later in 2013 to focus on fighting extradition to the United States.

In July 2015, Dotcom said publicly that he no longer owned shares in MEGA and was not involved in the company, claiming a "hostile takeover" by a Chinese investor later identified as Bill Liu (William Yan). By 2020, NZ Herald reported that ownership was distributed across NZ holding companies and private investors, with Beijing-based Li Zhi Min holding about 43% and Yang Jianhong about 24%. A subsequent corporate restructure involved Mona Ltd, a New Zealand holding vehicle.

As of 2024-2025, MEGA Limited is a privately-held New Zealand company with no publicly disclosed change in controlling ownership. Kim Dotcom has been legally separate from MEGA for roughly a decade at this point. The Megaupload predecessor was a legally and technically distinct entity that no longer exists. If you're evaluating MEGA as a product, the Dotcom connection is history, not current operations.

Whether that reputation still affects you as a user is a different question. We'll get to that in the piracy section.

Where does MEGA actually break?

The desktop sync engine still has reliability issues. MEGAsync, the Qt-based desktop client for Windows, Mac, and Linux, was rewritten in 2023 specifically to fix long-standing sync bugs. The rewrite improved things substantially. It didn't fix everything. The meganz/MEGAsync GitHub issue tracker still shows recurring 2024-2025 reports of endless upload/download loops, "Files in this folder can't be synced or backed up" errors, and desktop clients stuck in "Syncing" state on Windows. At scale (8TB+ or millions of files), reports of sync failures remain common.

Our experience: on moderate file counts (under 100,000 files), MEGAsync is stable. On large archives, it's fragile.

Account bans for unusual API traffic. This is the one that hurts legitimate power users. MEGA has automated systems that flag accounts for "unusual overhead" or traffic patterns that resemble abuse, and the practical effect is that rclone users and people running heavy backup scripts occasionally get swept into automated bans. The rclone forum has multiple threads of users locked out of accounts with no warning and a slow appeals process. The MEGA free-tier bandwidth cap exists partly because of abuse; the collateral damage is legitimate heavy users.

MEGA terminates accounts for DMCA strikes. Three strikes in six months equals account termination. MEGA cannot see file contents because of client-side encryption, so DMCA action targets public share links and file identifiers (hashes) rather than plaintext files. When a link is reported and validated, MEGA can and does disable the underlying file identifier, which means the file becomes inaccessible to everyone who has the link even though MEGA still can't read it. Files that are never publicly shared are effectively untouchable by DMCA because MEGA has no visibility.

Customer support is email-only and slow. No phone, no live chat, and response times commonly range from three to seven days. Non-billing tickets sometimes receive no response at all. The Reddit and Capterra complaint pattern is consistent across 2024-2025. If you expect responsive support, MEGA is not going to provide it.

MEGA Chat and collaboration features are behind the market. MEGA Chat works for 1:1 and group messaging with end-to-end encryption, and file-in-chat sharing is convenient. Real-time document collaboration (the Google Docs equivalent) doesn't exist. Version history is minimal. If you're using MEGA for team work, you'll want a separate tool for collaborative editing.

No native iCloud or Drive-equivalent mobile integration. iOS and Android apps are solid for viewing, uploading, and downloading files. They don't integrate with the OS the way Files On-Demand does on Windows OneDrive. Camera auto-upload works reliably on both platforms.

Is MEGA's piracy reputation fair?

Partially fair, partially outdated, and worth understanding before you decide.

The reputation comes from a few sources: Kim Dotcom's Megaupload history, MEGA's early marketing, MEGA's architectural commitment to client-side encryption (which structurally makes it harder to police hosted content), and the reality that pirate communities have historically posted MEGA links heavily. TorrentFreak has reported that MEGA terminated tens of thousands of accounts for repeat infringement, including 95,000 accounts by December 2020 and over 144,000 by October 2021. By March 2022, the total had crossed 744,000 accounts closed for objectionable content.

The practical impact on legitimate users is real in two narrow ways:

1. Heavy API traffic gets flagged. If you use rclone, backup scripts, or automation tools against MEGA, you risk automated bans. Other providers have this problem too, but MEGA's detection is more aggressive.
2. Shared-link bandwidth throttling hurts legitimate large distributions. If you're trying to share a 10GB file with 100 people from a free account, the bandwidth cap will catch recipients quickly and some of them will fail to download.

For everyday personal storage, neither of these matters. MEGA is fine for photos, documents, backups, and personal files. For business-critical sole-copy backup of data you absolutely cannot lose, we'd point you elsewhere. Not because MEGA will lose your data, but because the combination of automated bans, slow support, and legacy crypto debt makes it a bad single point of failure.

Pros and Cons

Who should actually use MEGA?

• Privacy-focused users who want a large free tier with real client-side encryption
• Linux desktop users who need a native client and an official CLI tool (MEGAcmd)
• People outside the US, UK, and EU who prefer New Zealand jurisdiction for personal files
• Secondary cloud storage for users who already have a primary cloud and want encrypted backup on a second platform
• Anyone sharing large files occasionally who can benefit from the generous transfer quotas on paid Pro plans

Skip MEGA if you need a single point-of-failure cloud for business-critical data, if you run heavy backup automation that might trip the ban detection, if you're in a country where the free tier bandwidth cap will be hit constantly, or if you want real-time document collaboration as part of your cloud storage product.

FAQ

Is MEGA safe to use after the 2022 cryptographic attack paper?

Mostly, with caveats. The ETH Zurich paper in June 2022 exposed five attacks against MEGA's cryptosystem, and MEGA released patches a week later that directly addressed three of the five issues and added integrity checks that block practical exploitation of the rest. No new cryptographic break has been published since. Current security is substantially better than the 2022 disclosure made it sound, but the underlying legacy architecture still has theoretical debt that MEGA said would take years to fully clean up. For personal files and routine privacy, MEGA is fine. For files where your threat model involves nation-state-level adversaries specifically targeting you, Proton Drive, Tresorit, or Sync.com have cleaner architectures.

Does Kim Dotcom still own MEGA?

No. Dotcom founded MEGA in January 2013, resigned as a director later that year, and publicly stated in July 2015 that he no longer owned shares in the company. As of 2024-2025, MEGA Limited is a privately-held New Zealand company with ownership distributed across NZ holding companies and private investors. The Kim Dotcom era ended about a decade ago, and MEGA is legally and technically separate from his previous company, Megaupload.

Why do I keep hitting a bandwidth limit on MEGA free?

Because MEGA enforces an IP-based transfer cap on free-tier accounts, roughly 5GB per rolling 6-hour window. Logging out and back in doesn't reset the cap because it's tied to your IP address, not your account. The fix is to wait about six hours for the rolling window to reset, change your IP via a VPN, or upgrade to any paid Pro tier to remove the cap entirely. The bandwidth cap also applies when downloading shared links from other users' accounts, which is why recipients of large MEGA shares sometimes get blocked midway through.

How much free storage does MEGA actually give you?

20GB permanent storage for new accounts. Older reviews sometimes quote "up to 50GB free" based on MEGA's Achievements bonus system, but MEGA scaled that back — most achievement bonuses are now time-limited (365 days or less) and revert after expiration. Plan for 20GB. Anything extra is a short-term bonus that won't persist.

Is MEGA's encryption really zero-knowledge?

Yes, in the sense that MEGA's servers never see your plaintext files or the master key under the normal authentication flow. Files are encrypted client-side with AES-128 before upload, and keys are derived from your password. The 2022 ETH Zurich attack paper exposed some theoretical weaknesses in MEGA's cryptographic architecture, most of which MEGA patched. For day-to-day use, MEGA is genuinely zero-knowledge. For a threat model that includes sophisticated adversaries, the cleaner architectures are Proton Drive and Sync.com.

Can MEGA terminate my account?

Yes. MEGA's terms of service enforce a three-strike DMCA policy — three validated infringement strikes in a six-month window equals account termination. Beyond DMCA, MEGA has automated systems that flag accounts for unusual API traffic patterns, which occasionally sweeps up rclone users, heavy backup automation, and other legitimate power users. Appeals exist but are slow. If you use MEGA for anything important, keep a backup elsewhere. This is good advice for any cloud provider; it's essential advice for MEGA specifically.
