Acrobat: "…not a supported file type or … the file has been damaged".
Acrobat says the file is not a supported file type or the file has been damaged when it cannot identify or parse a usable PDF structure. Upload the file for a repair attempt and see a free watermarked preview from any validated rebuilt PDF before you decide.

Here's what we recovered.
Review the watermarked preview before checkout.
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.

We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.
What stopped you continuing? One tap tells us why.
Try a deep repair
The repair engine can try a longer pass on the file you already uploaded.
Machine-only processing; no human views files; nothing is sent to an outside AI.
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, OPUS, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, RAR, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

Why this happens
Acrobat uses this message when the uploaded bytes do not form a PDF it can parse. The file may have non-PDF bytes under a .pdf name, a missing or displaced PDF header, or damaged cross-reference and trailer data that prevents the reader from locating page objects.
A real PDF can therefore trigger the same message as a mislabeled download. When PDF objects remain in the file, a recovery-aware rewrite can reconstruct cross-reference information and serialize the readable objects into a new document; when the bytes belong to another format, repair cannot manufacture the expected PDF.
FileFix runs independent recovery and rewrite paths, reopens each candidate without recovery mode, and only offers a result with at least one readable page. The free preview shows watermarked pages from that validated file and does not claim that absent objects were restored.
What we can and can't recover
We can usually fix
- PDFs that show "the file is damaged and could not be repaired"
- PDFs Chrome or Edge won't open ("Failed to load PDF document")
- Files cut off mid-download or mid-save
- PDFs with a broken cross-reference table or trailer
We can't fix
- Password-protected or encrypted PDFs
- Genuinely empty (0-byte) files
- Deleted or formatted files (that's data recovery, a different job)
- Pages whose content was never written to disk
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 watermarked pages from the repaired PDF and the recovered page count.
-
Pay & download If the preview shows what you need, unlock the repaired PDF for a one-time $12 USD.
You see watermarked pages from the repaired PDF and the recovered page count before you decide anything — so you never guess.

Questions
Acrobat uses this message when the bytes do not form a PDF it can parse. The upload may be another format saved with a .pdf name, or a real PDF with damaged header, cross-reference, or trailer data.
No. If the upload contains HTML, an image, or another format rather than PDF objects, repair cannot manufacture the missing document. Download the file again from its original source.
It reopens each candidate with recovery mode disabled and only offers a result containing at least one readable page. The preview shows watermarked pages from the validated PDF and the recovered page count.
A one-time $12 USD — and only if the repair works. Seeing what was recovered is free, and checkout is only offered when the engine produces a validated repaired file.
