TeraBox to MEGA: Move to Zero-Knowledge Encryption You Actually Hold

Move TeraBox files to MEGA for zero-knowledge end-to-end encryption and 20 GB free. Browser, MEGA desktop app, or a cloud-to-cloud transfer with CloudsLinker.

Introduction

MEGA encrypts every file end-to-end with zero-knowledge keys held only by you, applied by default across the whole service — which is exactly what TeraBox does not do, since TeraBox holds its own encryption keys and can scan or be compelled to hand over stored files. For anyone who put personal documents, scans, or private media on TeraBox and later read the fine print, that difference is the reason to leave. MEGA's free 20 GB is smaller than TeraBox's headline 1 TB, but it is private in a way TeraBox structurally is not. TeraBox exposes no OAuth API, so the export depends on its browser cookie. This guide covers a browser download, the MEGA desktop app as a bridge, and a cloud-to-cloud transfer with CloudsLinker.

About TeraBox

TeraBox is a consumer file locker from Flextech Inc., with roots in Baidu Netdisk. Its large free tier comes without zero-knowledge encryption — the provider holds the keys.

Free quota: 1 TB advertised; ~80 GB practical (20-file cap).
Encryption: server-side; TeraBox holds the keys and can scan files.
Open source: no.
Per-file cap: 4 GB free / 20 GB Premium.
Access: browser cookie (ndus, ndut_fmt); no OAuth.

About MEGA

MEGA is a New Zealand-based storage service built on zero-knowledge, end-to-end encryption applied to all files by default. The free tier starts at 20 GB.

Zero-knowledge encryption: files encrypted on your device; only you hold the keys.
Free tier: 20 GB baseline, expandable via bonuses.
Bundled privacy apps: MEGA VPN, Pass, and encrypted chat on paid plans.
Clients: web, MEGAsync desktop, mobile apps.
Access: account credentials (email + password; 2FA if enabled).

Why Move From TeraBox to MEGA?

This migration is almost entirely about who can read your files. TeraBox stores them server-side with keys it controls; MEGA encrypts them so it cannot read them at all.

Keys you hold: MEGA encrypts client-side, so the provider — and anyone who compels it — cannot read your files. TeraBox holds its own keys.
No content scanning of plaintext: because MEGA never sees plaintext, it cannot scan your files the way an unencrypted locker can.
Default, not optional: MEGA's encryption is on for everything automatically — there is no setting to forget.
Lower account-seizure risk to your data: even if an account is actioned, encrypted contents are not readable by the provider.

The trade-off is capacity: 20 GB free versus TeraBox's headline 1 TB. For sensitive data, most people decide privacy outweighs raw space. The methods below move the files across.

Preparing to Move TeraBox to MEGA

On the TeraBox side

Prioritize sensitive files: scans, IDs, financial records, private media — these are what the move is for, and they fit within 20 GB more easily than a full library.
Keep the session live: every method depends on a current cookie or login.
Plan around the 20 GB free ceiling: a large TeraBox library will not fit a free MEGA account — either select a subset or choose a MEGA paid plan.

On the MEGA side

Save your Recovery Key: because MEGA is zero-knowledge, losing your password without the Recovery Key means losing access to the encrypted data. Store it safely.
Enable 2FA on the MEGA account before connecting any tool.
Create a target folder such as /TeraBox-Import/.

Method 1: Browser Download from TeraBox, Upload to MEGA

Step 1: Download from TeraBox

Sign in at terabox.com and download the files you want to protect. Free downloads run one at a time; prioritize sensitive items first.

Download files from the TeraBox web interface

Step 2: Upload to MEGA

Open mega.nz, open your target folder, and drag the files in. MEGA encrypts each file in your browser before it leaves your device, so the upload is end-to-end encrypted by the time it reaches MEGA's servers.

Method 2: MEGA Desktop App (MEGAsync) as a Bridge

Best for a larger set, with encryption handled locally

MEGAsync mirrors a local folder to your encrypted MEGA account, encrypting client-side as it uploads. Download from TeraBox into a synced folder and MEGAsync does the rest.

Step 1: Install MEGAsync and Pick a Synced Folder

Install MEGAsync, sign in, and configure a local folder to sync to a MEGA destination (for example, TeraBox-Import).

Step 2: Download TeraBox Files Into It

Using the TeraBox desktop app or browser, download into that synced folder. MEGAsync encrypts and uploads each file as it appears. Wait for the sync indicator to clear, then verify in the MEGA web app before removing local copies.

Method 3: Cloud-to-Cloud Transfer with CloudsLinker

Move It Server-Side, Into Your Encrypted Account

CloudsLinker reads from TeraBox by cookie and writes into MEGA using your account credentials, running server-side and retrying through TeraBox's throttle. Files are stored encrypted on MEGA once they arrive.

Step 1: Connect TeraBox (Browser Cookie)

In CloudsLinker, click Add Cloud → TeraBox and supply the session cookie:

Install EditThisCookie (V3) in Chrome.
Open www.terabox.com in the same browser, signed in.
Click EditThisCookie → Export to copy the cookie JSON.
Paste it into CloudsLinker and confirm.

Or copy the Cookie header (ndus=...; ndut_fmt=...) from DevTools (F12) → Network.

Connect TeraBox to CloudsLinker with the browser session cookie

Step 2: Connect MEGA

Click Add Cloud → MEGA. Enter your MEGA email and password, and the 2FA code if you have it enabled. MEGA appears as a connected destination. Files written here are stored under MEGA's encryption.

Connect MEGA to CloudsLinker with account credentials and 2FA

Step 3: Configure the Transfer

In the Transfer section, set TeraBox as the source and MEGA as the destination with your /TeraBox-Import/ folder. Filter by type, size or date — useful for selecting just the sensitive files that justify the move. Copy mode keeps TeraBox intact until MEGA is verified.

Step 4: Start and Monitor

Start the task and watch the Task List. If the TeraBox cookie expires, the task pauses for a fresh one. After completion, open MEGA and confirm the files — then delete the TeraBox copies of anything you wanted off the unencrypted service.

Practical Tips for TeraBox to MEGA

Back up your MEGA Recovery Key first: zero-knowledge encryption means MEGA cannot reset your data if you lose the password. Store the Recovery Key somewhere safe before you move anything important.
Move sensitive files first: the 20 GB free tier favors a curated set — documents, scans, private media — over a full bulk library.
Grow free space with bonuses: MEGA adds storage for installing apps and other actions, which can stretch the free 20 GB a bit further.
Delete TeraBox copies of private data: the privacy gain only fully applies once the unencrypted TeraBox copy is gone — after verifying MEGA.
Refresh the cookie before long jobs: re-login to TeraBox right before exporting the cookie for CloudsLinker.
Enable 2FA on MEGA: pair strong encryption with two-factor login so the account itself is hard to compromise.

Frequently Asked Questions

Once files are stored in MEGA, they are held under MEGA's zero-knowledge encryption with keys only you control. With the browser and MEGAsync methods, encryption happens on your device before upload. With a server-side transfer, files are encrypted at rest in your MEGA account on arrival.

Yes. CloudsLinker preserves the TeraBox hierarchy automatically; browser and MEGAsync methods preserve it if you keep folders intact.

Because MEGA is zero-knowledge, it cannot recover your data without your Recovery Key. Save that key before moving important files. This is the trade-off of provider-blind encryption: stronger privacy, more responsibility on you.

TeraBox uses the browser session cookie (no OAuth API). MEGA connects with your account email and password, plus a 2FA code if enabled. Change the MEGA password after the move if you prefer to rotate access.

The transfer pauses and remaining files are flagged. Either select a smaller, sensitive subset, earn bonus storage, or move to a MEGA paid plan. CloudsLinker resumes and skips files that already landed.

Yes — and that is usually the right call. CloudsLinker filters by folder, type, size and date, so you can pull just the sensitive material into MEGA's 20 GB and leave bulk media on TeraBox or move it elsewhere.

Data travels over TLS, and files are encrypted at rest in MEGA. The TeraBox cookie is tied to your session — log out and back in to invalidate it afterward. For the strongest client-side guarantee end to end, the MEGAsync or browser methods encrypt on your device before upload.

Conclusion

For a few files, the browser download into MEGA's web app encrypts them on the way in. For a larger set, MEGAsync mirrors a local folder up to your encrypted account. For a hands-off move, CloudsLinker connects TeraBox by cookie and MEGA by account credentials, transferring server-side and retrying through TeraBox's throttle. Whatever the route, the privacy gain is the same: once files land in MEGA they are encrypted with keys only you hold. Keep the 20 GB free ceiling in mind, and treat sensitive files as the priority for the move.
