Not guaranteed to be perfect — but it rebuilds a fresh, working PDF from whatever can be recovered, and tells you exactly how much.

Recover text with AI cleanup
When a page's original text can't be recovered, OCR reads it from the rendered page and AI fixes obvious misreads. Turn off to keep it 100% local, raw OCR only.
Disclaimer: this tool makes a best-effort attempt to recover a damaged PDF — it does not guarantee complete or error-free recovery. Recovered pages are re-rendered images, and any text recognized via OCR (with or without AI cleanup) can contain misreads, especially on garbled or low-quality source material. Always visually check the recovered file against what you expect before relying on it — don't treat it as a certified, legally faithful copy of the original for contracts, IDs, financial records, or other important documents. If the original file still exists somewhere (backup, email, cloud storage), that's always a more reliable source than a repaired reconstruction.

Frequently asked questions

What kinds of PDF damage can this fix?

Damaged internal structure, truncated files, and pages with corrupted content are the most common issues this tool can recover from by rebuilding a fresh, valid PDF from whatever's still readable.

What does the recovery percentage mean?

It's the share of pages successfully recovered — either with their original content intact, or reconstructed via OCR when the original text stream was unreadable. 100% doesn't guarantee a pixel-perfect match to the original, just that every page produced usable output.

Is my file sent anywhere?

No, repair runs entirely in your browser. If AI cleanup is on, only OCR-recovered text from pages that were missing their original text may be sent externally to fix misreads — never the file itself.

Can this recover a PDF that won't open at all?

Often yes. The tool doesn't rely on the file opening cleanly first — it scans for whatever valid objects and page content still exist, even in a file your PDF viewer refuses to open.

Should I use the repaired file for legal or financial documents?

Treat a repaired file as a best-effort reconstruction, not a certified faithful copy. For contracts, IDs, or financial records, always try to locate the original file (backup, email, cloud storage) first.
