How to repair a PDF online
Upload your damaged or corrupted PDF using the box above. We rebuild the file's internal structure — fixing broken cross-reference tables and object streams — so it opens correctly in any PDF viewer.
What kinds of PDF problems can this fix?
This tool addresses structural corruption: files that won't open, show a blank page, or display "damaged file" errors in your PDF reader. It does not recover pages that were genuinely deleted, or unscramble content lost to disk corruption beyond the file's internal structure.
💡 Tip: if repair doesn't fully fix your file, try re-exporting or re-scanning the original document — some damage happens upstream of the PDF itself.
