Repair a Damaged PDF Online for Free
A PDF can stop opening after an interrupted download, a failed save or a broken email attachment. This tool reads what is still readable in the file and builds a new PDF from it, right in your browser.
How to repair a PDF
- Select the damaged PDF, or drop it on the page.
- Keep the Automatic method, or choose Pictures only.
- Click Repair PDF.
- Check the summary, then download the repaired file.
Two repair methods
Automatic rebuilds the file page by page and keeps text, links and images. Any page it cannot rebuild is drawn and added as a picture. Pictures only skips the rebuild and saves every page as a picture, which is the most reliable choice but removes selectable text.
What can and cannot be recovered
- A broken index, wrong page count or extra data at the start of the file can usually be fixed.
- A page with damaged content may come back as a picture.
- Content that is missing from a cut-off file cannot be restored.
A PDF tool that respects your privacy
Damaged files are often important ones. This tool works inside your browser, so the file is never sent to a server.
