Repair a broken .zip file.
A broken .zip may contain readable local file records even when its final index is gone. FileFix scans those records, decompresses recoverable entries, writes a new central directory, and shows the rebuilt file list for free. A one-time $5 — and only if the repair works.
Free preview — pay only if you download ($5)
Your files auto-delete — delete them sooner anytime
No person looks at your file as part of repair

Simulated checkout — no payment is processed.
Optional — we'll email your private download link.
You preview before you pay. If the download is materially worse than the preview you approved, we'll refund you.

There's nothing to repair. If it still looks broken, the issue may be the player, codec, or viewer on your device rather than the file itself.
We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
Unrepaired files are kept encrypted for up to 30 days, then deleted.
FileFix can't fix that kind of file yet.
Right now we repair video, audio, document, and image files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, FLV, M4A, WAV, MP3, AAC, FLAC, OGG, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

Why this happens
ZIP readers normally use the central directory to locate members. If that index is missing, damaged, or inconsistent, the reader can reject the archive even though local records and compressed data remain earlier in the file.
Everything happens online, in the browser: you don't install anything, and you don't create an account to try it. The free part is the recovery summary — the list of files the rebuilt archive contains and whether they can be read. You only decide about paying after you've seen that list.
Before uploading, it's worth one re-download or re-copy from the original source if you still have it, and a second attempt with a different extractor — Windows' built-in ZIP reader is stricter than many dedicated tools, so a file Explorer refuses will sometimes open elsewhere. When every tool refuses it, the archive structure itself is damaged, and rebuilding it from the surviving records is the remaining option.
The repair scans each surviving local header, checks the compression method and safety limits, attempts decompression, and creates a new archive from the recovered bytes. The new ZIP gets its own central directory rather than copying the damaged one.
The summary opens the rebuilt archive and reads its entries to produce file and readability counts. That confirms the output container can be inspected; it cannot certify the semantic contents of every recovered document, image, or database inside it.
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. The repair runs automatically — no person looks at your file.
-
Free Watermarked Preview You see exactly what we recovered — the list of files recovered from the archive.
-
Pay & Download If the summary shows what you need, unlock the repaired ZIP archive for a one-time $5.
You see a recovery summary built from your actual file before you decide anything — so you never guess.

Questions
No. The upload, repair, and recovery summary all happen in the browser, and the rebuilt archive downloads as a standard ZIP that opens with the tools you already have.
The recovery summary is free — you see the list of recovered files and whether they can be read before anything else. Payment only comes into it if the summary shows what you need and you choose to unlock the rebuilt archive.
The engine writes the decompressed bytes it recovered into new ZIP entries. If a compressed stream was damaged, those bytes may be incomplete; the engine does not invent replacement content.
The on-page summary caps the displayed file list and notes when more entries exist. The count describes the rebuilt archive, while the preview remains compact.
Recovered entry names include their stored paths, and those names are used when the new ZIP is written. A path whose local record is missing cannot be recovered.
