FileFix

PDF won't open after download

A PDF that won't open after download may have arrived without its complete tail, trailer, or cross-reference data. Try downloading it again first; if no clean source remains, FileFix can test the saved bytes and summarize any validated rebuild. A one-time $12 — and only if the repair works.

Here's what we recovered.

Repair your file

Choose a supported file to see what can be repaired before checkout.

You preview before you pay. If the download is materially worse than the preview you approved, we'll refund you.

Good 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. You can try another file.

FileFix can't fix that kind of file yet.

Right now we repair video, audio, and document files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, M4A, WAV, MP3, AAC, FLAC, OGG, AIFF, XLSX, DOCX, ZIP, and PDF). We're adding support for more formats over time.

We store just your email and the file type — never the file itself. One message, when it's ready. No spam.

Something went wrong.

The request could not be completed.

Why this happens

A download can keep a .pdf filename while ending before all document bytes arrive. That truncation commonly removes the trailer and cross-reference data near the tail, which is distinct from a file whose PDF header is missing at the beginning.

A fresh download is the best fix when the source remains available because repair cannot supply bytes that never arrived. When only the truncated copy remains, page objects stored before the cut may still be recoverable.

FileFix scans and rewrites the surviving PDF objects, validates candidates without recovery mode, and shows page and object counts from any readable result.

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

  1. Upload Drop the file in. It uploads over an encrypted connection. The repair runs automatically — no person looks at your file.
  2. Free Watermarked Preview You see exactly what we recovered — page and object counts and a short excerpt of recovered text.
  3. Pay & Download If the summary shows what you need, unlock the repaired PDF for a one-time $12.

You see a recovery summary built from your actual file before you decide anything — so you never guess.
