Repair PDF
Attempt to recover and fix damaged or corrupted PDF files.
How to repair a damaged or corrupt PDF online
Upload the damaged PDF
Drag the file that won't open correctly, or click to select it from your computer.
The tool attempts to rebuild it
The file is reopened with a more lenient analysis and its internal structure is rewritten, to try to fix common errors.
Download the repaired PDF
If the repair is successful, you download a new, working file. Keep in mind that not every type of damage can be fixed from the browser alone.
Why repair your PDFs on PDFDocks?
A corrupted PDF or one that doesn't open properly often contains exactly the information you need to recover urgently. Uploading it to an external server to try fixing it adds an unnecessary exposure step to a file that already worries you. At PDFDocks, the repair attempt is done with JavaScript, directly in your browser: the file never leaves your device. Let's be honest about expectations: this is a "best effort" repair that reopens the file with more permissive analysis and rewrites its internal structure to fix common formatting errors. Not all types of damage can be fixed this way — if the file is severely corrupted at the binary data level, no browser-based tool will be able to recover it completely.
What kinds of damage can be repaired?
+
Yes. Your file is never uploaded to a server: the repair attempt is performed directly in your browser with JavaScript.
Can this tool repair any type of damage?
+
No. It's a best effort repair that corrects common structural errors. If the file is severely damaged at the data level, it may not be fully recoverable.
Is my corrupted PDF uploaded to a server when using this tool?
+
No. All repair attempts happen in your own browser, without the file traveling across the internet.
Is my PDF private?
+
Yes, no installation is needed. It works directly from your browser, with no account creation or additional software downloads required.
What if the repair doesn't work?
+
If the damage is too severe, the tool will clearly indicate this instead of generating a file that looks repaired but isn't actually fixed.
Is it free to try repairing a PDF?
+
Yes, the tool is completely free with unlimited uses.
