Frequently asked questions
Is the Repair PDF tool free?
Yes, it is completely free. There is no signup, no subscription, and no watermark added to your repaired file.
Is it safe and private to repair my PDF here?
The tool runs in your browser and is used only to repair the file you upload. We do not ask you to register or hand over personal details to use it.
Can every corrupted PDF be fully recovered?
It depends on how badly the file is damaged. Light corruption is usually fixed and the content comes back, but severely broken files may only be partly recovered. It is worth keeping a copy of the original before you repair it.
Are there limits on file size or number of files?
You can repair PDFs without creating an account. Very large or extremely damaged files may take longer to process or may not recover fully.
Does it work on a phone?
Yes. The tool works in any modern browser on mobile and desktop, so you can repair a PDF from your phone, tablet, or computer.
Will repairing change the quality of my PDF?
The tool rebuilds the file structure and keeps the readable content as it was. It does not re-compress or downgrade text and images; it simply restores access to what could be recovered.
