ZIP archive recovery options and guides.
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. If the summary shows what you need, unlock the repaired ZIP archive for a one-time $5.

Repair your file
Choose a supported file to see what can be repaired before checkout.
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.
Try another fileGood news — your file isn't damaged. No charge.
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 ZIP archives stop opening
A ZIP stores a local record beside each compressed member and a central directory near the end that acts as the archive-wide index. Many archive tools begin with that final directory. If it is missing or inconsistent, they may reject the archive without checking each earlier member.
Interrupted downloads and copies commonly damage the tail first. Damage can also land inside an individual compressed member: in that case the directory may exist, but that member's bytes or checksum no longer agree with its record.
FileFix scans the local records directly, decompresses stored and DEFLATE members under safety limits, and writes the readable results into a new ZIP with a fresh central directory. The output is therefore based only on entries found in the uploaded bytes.
The recovery summary lists rebuilt entries and tests whether they can be read from the new archive. A readable archive does not mean that missing tail bytes or a missing split-archive part were recreated; file repair cannot invent them.
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. 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
The engine scans the archive bytes for each surviving local file header, decompresses the readable entry data, and writes those entries into a new ZIP with a fresh index.
It shows how many entries are in the rebuilt archive, how many can be read, and a file list with names and sizes. Long lists may be shortened in the on-page summary.
It preserves bytes emitted from a damaged compressed stream when possible, but a truncated member may be incomplete. Missing bytes cannot be reconstructed. The recovered-file list and readability count describe the rebuilt archive, not the completeness of every file's contents.
No. The archive carries entry names and paths in its local records. FileFix works from the ZIP file you upload.
No. The engine does not decrypt archive entries or bypass passwords.
No. A split archive depends on all of its numbered parts. FileFix cannot manufacture a missing part or fetch it from the source.
A one-time $5 — and only if the repair works. The recovered-file summary is free, and checkout is unavailable if the engine cannot produce a rebuilt archive with recovered members.
No person does. The engine automatically decompresses entries to rebuild and verify the archive. Originals of successful repairs are deleted when your repair is delivered; unrepaired files are kept encrypted for up to 30 days, then deleted.
The current scan handles stored entries and standard DEFLATE entries. An entry using a different compression method may not be included in the rebuilt archive.
No. FileFix repairs an archive file you still have. Recovering a deleted file from a drive or memory card is a separate data-recovery task.
A CRC mismatch means the decompressed bytes do not match the checksum stored in the damaged entry record. The scanner can preserve bytes it emitted, but that mismatch is evidence the member may be incomplete or altered.
ZIP readability checks whether an entry can be read from the new container. They do not validate the internal rules of every file format inside it. A recovered document or image can still contain its own damage.
The scanner enforces entry-count, decompressed-size, and compression-ratio limits. Archives that exceed those safety bounds are rejected rather than expanded without a limit.
