ABOUT THIS TOOL
How Repair PDF works
Rebuilds a damaged cross-reference table and object structure — the usual reason a PDF opens blank or refuses to open.
- Rebuilds a broken cross-reference table automatically
- Falls back to visual page recovery if needed
- Fixes the most common “cannot open” errors
Runs 100% in your browser
docflo processes this file using JavaScript on your own device. It's never uploaded, stored, or seen by anyone else — and it works even if your connection drops mid-way.
FAQ
Frequently asked questions
What kinds of damage can this fix?
Most “this file is damaged” and “cannot open” errors come from a broken cross-reference table or bad object offsets — both get rebuilt. If the structure is too far gone, docflo falls back to recovering each page visually.
Is Repair PDF free?
Yes, and there is no sign-up, watermark or daily limit — everything runs in your browser rather than on a metered server.
