Transfer files from MEGA to iCloud Drive
Server to server, without downloading anything to your computer.
How it works
Connect both accounts once. ShiftMyData then talks to MEGA and iCloud Drive directly and streams the files between them in memory — nothing is written to our disks, and nothing travels down to your machine and back up again. The job runs on a worker, so closing the tab does not stop it.
Will every file be verified?
MEGA exposes no checksum through its API, so files are compared on size and modification time. That is a limit of MEGA rather than of the transfer, and it applies whichever tool you use.
Before you start
- The largest single file iCloud Drive accepts is 50 GB. A bigger one is reported as failed and the rest of the transfer carries on.
- MEGA treats Report.pdf and report.pdf as two files; iCloud Drive treats them as one. Where both exist in one folder, only one arrives, so rename one first.
- MEGA allows two files with exactly the same name in one folder, and iCloud Drive does not. Only one of each such pair is copied; rename duplicates before you start if you need both.
- A transfer copies each file's current content, name and modification time; sharing and version history stay behind on MEGA. Business migration carries them where both sides support them.

Worth knowing about MEGA
MEGA exposes no checksum through its API and rate-limits free accounts aggressively. Transfers are compared on size and modification time, and a large move from a free account will be throttled by MEGA rather than by us.
Worth knowing about iCloud Drive
Apple publishes no official API for iCloud Drive. The connection uses an unofficial one, signed in with your Apple ID password and a code Apple shows on your device, and Apple can change it without notice -- so treat iCloud as best-effort rather than as something to schedule a nightly job against.
Steps
- On the Clouds screen, add MEGA: enter your MEGA email and password.
- Add iCloud Drive the same way: enter your Apple ID and password, then the code Apple shows on one of your devices.
- Pick the source folder in the left pane and the destination folder in the right.
- Choose a mode — copy, mirror, move, or two-way — and start the transfer.
- Leave it. Progress is on the Jobs screen, and a webhook can tell you when it ends.
Questions
Do I have to download my files from MEGA first?
No. The transfer is streamed from MEGA to iCloud Drive on our servers, so nothing is written to your machine and your home upload speed is not the limit.
What happens if I close my laptop?
The job keeps running. It is queued on a worker rather than in your browser, and the progress is there when you come back.
How do I know every file arrived?
MEGA exposes no checksum through its API, so files are compared on size and modification time. That is a limit of MEGA rather than of the transfer, and it applies whichever tool you use.
Is there a size limit?
None imposed by us. What you move is drawn from your prepaid allowance (30 GB free, then 500 GB for ₹100 or 2,500 GB for ₹500, each valid a year). iCloud Drive takes single files up to 50 GB, and its own storage quota applies.
