Interrupted downloads, failed email attachments and buggy generators leave PDFs that readers refuse to open — “file is damaged”, “cannot be repaired”. Many of them are recoverable: the content is there but the index that points to it is broken. Repair rebuilds that index and re-saves the file cleanly.
If the structure is too far gone, the tool falls back to rendering every page that can still be displayed and building a new PDF from those images. The repair runs in your browser, so a sensitive document is not sent anywhere.

Frequently asked questions
Nothing could be recovered — what now?
The file may be truncated beyond the page content or not a PDF at all. Ask the sender for a fresh copy.
Will the repaired file be identical?
With structure rebuild, page content is unchanged. Re-rendering turns pages into images.
Is my file uploaded?
No. Everything runs in your browser.
