Recover data from a damaged or corrupt PDF file.
Recover data from a damaged or corrupt PDF file. Repair PDF runs entirely in your web browser, so your file is processed on your own device and is never uploaded to MyPDFMate.
Answers to the questions people ask most about using Repair PDF.
Open Repair PDF on MyPDFMate, upload the damaged file and click Repair PDF. The tool rebuilds the file's internal structure and gives you a fresh, clean PDF to download.
Yes. Repair PDF is free with no sign-up, and it runs in your browser, so the damaged file is never uploaded.
The most common causes are interrupted downloads, incomplete email attachments, unplugging a USB drive mid-copy, crashes while saving, and software that writes invalid PDF data.
Typical signs are errors like “the file is damaged and could not be repaired” or “failed to load PDF document”, blank or missing pages, or a file that opens in one viewer but not in another.
No. Repair works when the file's structure is broken but the page data is still there. If the file is truncated or 0 KB, the content is missing, so download or copy the file again from its source.
Download it again first, because an incomplete download is the most common cause. If it still won't open, run it through Repair PDF.
The file may be damaged, your reader may be out of date, or the file may not really be a PDF despite its extension. Try opening it in your browser; if it fails everywhere, repair it.
The readable pages are copied into a new, clean file, so the content stays the same. Bookmarks and some interactive elements may not carry over.
Garbled characters usually come from broken font information, not a damaged file, so Repair PDF won't change them. Convert the pages with PDF to JPG and run them through OCR PDF to recover readable text.
Remove the password with Unlock PDF first, then repair the unlocked copy.
