CopyProof: USB Photo Backup
Verified Copy to Any Drive
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Copy your whole photo library to a USB drive, SSD or SD card — up to 20 streams at once, every file checked with SHA-256. Resumes after any interruption.
CopyProof copies photos and videos from your iPhone, iPad or Mac library to an external drive or a folder you choose — in parallel and verified file by file. It only copies: nothing is ever deleted from your library.
MULTI-THREADED COPYING
Most apps copy one file at a time. CopyProof runs up to 20 parallel streams, so a large library moves in a fraction of the time. You choose the number of streams yourself.
EVERY FILE IS VERIFIED
Each copied file is checked with a SHA-256 checksum, so the copy is byte-for-byte identical to the original. Files that fail the check are listed and can be copied again with one tap.
RESUMES WHERE IT STOPPED
Drive unplugged, app closed, battery died — copying picks up exactly where it stopped, without re-transferring what is already done.
COPY ONLY WHAT YOU NEED
Copy the whole library or pick by album, year, month, media type or favorites, and exclude single files by hand. Split a large library into batches by year or by album.
TWO DESTINATIONS, NO INTERRUPTIONS
Add a second drive or folder as overflow. When the first one runs out of free space, copying continues to the second one automatically — no need to watch it or split the library by hand.
AN ORGANIZED ARCHIVE
Folders by year / month / day; newest or oldest first.
A REPORT AT THE END
See how many files were copied and verified, how much space they take, and which files need attention. Share the result card to earn bonus tokens: 200 for the first report, fewer for each next one.
TOKENS
One token per copied file. New users start with 1,000 tokens, extra copy streams are unlocked with tokens, and packs can be purchased at any time. There is no subscription — you pay only for what you use.
PRIVACY
Photos and videos go straight to your drive. Nothing is uploaded to any server.
