Frequently asked questions

How do I fix a PDF that won't open?

Open it here. The tool first rebuilds the file with qpdf, then tries reading its objects one by one, then cuts a truncated file back to its last complete part, and as a last resort redraws every readable page into a new PDF.

Can every corrupted PDF be repaired?

Not always. If parts of the file are missing, only the readable pages can be recovered, and the result tells you how many pages came back.

What does Recovered as images mean?

The pages could only be saved as pictures, so they look right but their text can't be selected. Run OCR PDF on the result to make it searchable again.

Is my damaged PDF uploaded?

No. The repair runs in your browser.
