Repair a damaged PDF online
Fix common PDF issues like corrupted structure, broken previews, or files that won’t open correctly in viewers. Upload your document to analyze it and repair when needed.
If the PDF doesn’t require repairs, the tool will tell you and you can download the original file without changes. When repairs are needed, you’ll get a repaired PDF you can safely share or print.
After repairing, you can compress the file, run OCR to make it searchable, or flatten it for consistent viewing across devices.
FAQ
What problems can PDF repair fix?
It can fix many structural issues that cause errors in viewers, broken previews, or failures when processing PDFs in other tools.
Will repair change the content of my PDF?
The goal is to preserve content and layout. Repair focuses on fixing the PDF structure so it opens and processes correctly.
Why does the tool say repair is not needed?
Because the inspection indicates your PDF is already valid and repairing it would not improve anything. You can download the original.
Can I repair scanned PDFs too?
Yes. Scanned PDFs are supported. If you need selectable text, run OCR after repairing.
What should I do if repair fails?
Try the tool again with the same file, or run compression/flattening first. If the PDF is heavily corrupted, export a new PDF from the original source if possible.
What’s a good next step after repair?
Compress for sharing, OCR for searchability, or flatten to ensure consistent rendering.
