"Unexpected end of archive" — how to recover the files inside.
Upload a ZIP archive that won't open. We rebuild it from what's still inside and show you a free recovery summary — the list of files we recovered from the archive. Paid downloads for document repairs are coming soon; while we finish testing, the summary is free.

Intro
A ZIP archive keeps its file index in a central directory near the end. When a download, copy, or save is interrupted, that directory can be cut off or damaged even though the files stored earlier in the archive are still intact. Archive tools then report an unexpected end of archive or refuse to open it at all.
FileFix reads the archive directly, rebuilds the index, and recovers every entry it can still read. Files whose bytes survived can be restored; missing or truncated data cannot be invented. You never install anything, and you don't create an account to try it. You upload, you read the recovery summary, you decide.
What we can and can't recover
We can usually fix
- archives that show "unexpected end of archive"
- archives cut off during a download or copy
- ZIP files with a damaged central directory
- archives that show the right size but won't open
We can't fix
- encrypted archives
- multi-part or split archives missing their other parts
- genuinely empty (0-byte) files
- files on physically damaged drives (that's hardware data recovery)
How it works
- Upload. Drop the file in. It uploads over an encrypted connection.
- We rebuild it. The repair runs automatically — no person looks at your file.
- Read the summary, then decide. You see exactly what we recovered — the list of files recovered from the archive. Paid downloads for document repairs are coming soon; while we finish testing, the recovery summary is free.
You see a recovery summary built from your actual file before you decide anything — so you never guess.

Questions
Is my file private?
Yes. Uploads travel over an encrypted connection, the repair is fully automated, no person looks at your file, and everything auto-deletes within 48 hours.
What does it cost?
Nothing right now. Paid downloads for document repairs are coming soon — while we finish testing, the recovery summary is free, and we don't ask for a card or an account.
What if you can't fix it?
Then we say so. If the data you need didn't survive, the summary shows that honestly — we'd rather tell you than waste your time.
How long does it take?
Usually a few minutes, depending on the file's size. You can watch the progress on the page.
Do I need to install anything?
No. Everything runs in your browser and on our servers — nothing to download, no add-ins, no macros.
