About Repair PDF
Repair PDF tries to rescue a file that won't open properly by reading what it can and saving a fresh, cleanly structured copy. It often fixes files damaged by an interrupted download or a faulty export.
How to use Repair PDF
- Add the damaged PDF.
- Press Repair PDF — there are no settings.
- Download the repaired copy.
- Open it in a different viewer to confirm all pages are present.
Tips for better results
- If repair fails, try downloading the file again from its source — a fresh copy is often fine.
- Some viewers are more tolerant than others; try a second browser before giving up.
- Keep the original in case a specialist tool can recover more later.
Limitations
Badly corrupted files, or pages whose data is missing, can't be recovered. Bookmarks and form fields may be lost.
Frequently asked questions
Is repair guaranteed to work?
No. It fixes common structural problems but cannot rebuild data that is genuinely missing.
Will it change my content?
It copies the pages it can read; it does not edit text or images.
Are my files uploaded?
Your file is processed by your own browser. It is not uploaded to our servers, and closing the tab clears it from memory.
