About this tool

Repair PDF Online

Repair PDF tries to fix a corrupted PDF that won't open or shows errors such as "file is damaged" or "could not be read". Upload the broken file and the tool first rebuilds its internal structure, keeping the original text and quality whenever possible.

If the structure is too damaged, a second method opens the file with a more forgiving PDF reader and recovers every readable page as an image. The result tells you which method worked and how many pages were recovered. This can rescue PDFs from interrupted downloads, failed email attachments, bad USB transfers or apps that crashed while saving.

Not every file can be saved: a badly truncated file may have nothing left to recover, and then re-downloading or exporting it again is the best option. The repair runs in your browser, so the damaged file is never uploaded.

  • Structure rebuild

    Intact objects are read and a new cross-reference table is written, preserving text and quality.

  • Page recovery fallback

    When the structure is too broken, readable pages are recovered as images.

  • Clear results

  • Accepts broken files

    Files are accepted even if they can't be opened or read normally.

Yes. Repair as many PDFs as you like for free, with no sign-up and no watermark.

First we read every object that is still intact and write a new cross-reference table, which keeps text and quality. If the structure is too broken, we open the file with a forgiving PDF reader and rebuild each readable page as an image.

If the structure repair works, yes. If pages had to be recovered as images, the text can no longer be selected or searched — the result tells you which method was used.

No. If a file is badly truncated or isn't really a PDF, there may be nothing left to recover. In that case we tell you, and the best option is to download or export the file again.

No. Your PDF is processed entirely in your browser and never leaves your device.
