How to Repair a PDF Online
A PDF can get damaged when a download stops halfway, a file is copied badly, an email attachment is cut, or a program crashes while saving. Often most of the pages are still inside the file. This tool tries to rescue them.
- Upload your PDF by clicking or dragging it into the upload area
- Read the quick check: it tells you if the start or end of the file is damaged
- Click "Repair PDF" to use the standard repair
- If the standard repair fails, use "Rebuild as images" as a last resort
- Download the repaired file, which starts automatically
- Open it and check the pages before you delete the original
Everything is done inside your browser. Your file is never uploaded.
Why Use This Repair PDF Tool?
When a PDF shows errors like "file is damaged and could not be repaired" or "failed to load PDF document", you do not have to lose your work. Many damaged files only have a broken table of contents inside, and rebuilding it brings the file back to life.
This tool checks every page of the repaired file, tells you which pages could be read, and can leave out the pages that are beyond repair, so you keep everything that can be saved.

Frequently Asked Questions
Can this tool repair every damaged PDF?
No. It works well when the file structure is damaged but the page content is still inside. If the page data itself is missing or destroyed, those pages cannot be recovered by any tool.
My download stopped halfway. Can I get the full file back?
The missing part is gone, so the file cannot be completed. But the pages that were fully downloaded can often be saved with this tool. Downloading the file again is the best fix.
What does "Rebuild as images" do?
It draws every page that can be shown on screen and saves each one as a picture inside a new PDF. This can save files the standard repair cannot, but the text in the new file cannot be selected or searched, and the file is usually bigger.
Can it repair a password protected PDF?
No. The password must be removed first. A file you cannot open with the password cannot be repaired.
Is my file uploaded to a server?
No. The repair runs inside your browser and your file never leaves your device.
Will the original file be changed?
No. A new repaired file is created and your original stays as it is.
Is it free?
Yes, this tool is completely free to use.
