Repair PDF
betaThis free Repair PDF tool rebuilds a corrupted PDF — a broken cross-reference table, a damaged trailer, or junk after the end of the file — so it opens again. Drop the file in and the recovery runs on your device; nothing is uploaded.
Repair fixes structural damage (a broken cross-reference table, damaged trailer, junk after the end of the file). If a normal repair doesn’t open, try Force rebuild, which reconstructs the file from whatever pages are still readable. Content that’s physically missing can’t be recovered.
How to use Repair PDF
- 1 Drop your damaged PDF onto the drop zone, or click to browse for it.
- 2 Click Repair PDF to fix the structural damage.
- 3 If it still won't open, click Force rebuild to reconstruct the document page-by-page from whatever pages are still readable.
- 4 Check the preview, confirm how many pages were recovered, then download the repaired file.
Frequently asked questions
Is my PDF uploaded to fix it?
No. The repair runs entirely in your browser, so a damaged file you may not fully trust never leaves your device and nothing is sent to a server.
What's the difference between Repair and Force rebuild?
Repair fixes structural damage like a broken cross-reference table or damaged trailer. Force rebuild is more aggressive — it reconstructs the file from whatever pages are still readable, for badly damaged PDFs.
Can it recover a PDF that lost content?
It fixes structural problems that stop a file from opening, but content that is physically missing from the file can't be recovered. Always check the preview before saving.
Why won't my file repair?
If a normal repair can't produce an openable document, try Force rebuild for a more aggressive recovery. Some files are too damaged to rebuild if the underlying page data is gone.
