How to repair a PDF
To use Repair PDF, add one damaged file and let the tool run its recovery flow. It first tries a direct rebuild of the document, and if that is not enough it falls back to recovering readable pages so the usable content is preserved in one fresh export. On a partial recovery, it tells you which pages could not be saved.
Everything runs locally in your browser, so your damaged PDF never leaves your device. That keeps the file private even when you are trying to rescue an important or sensitive document.
When the repair finishes, you can export the recovered PDF and check whether the pages you need came through.
- Add one damaged PDF
- The tool tries a direct rebuild first
- Readable pages are recovered if needed
- Export the recovered PDF
What best-effort repair means
Repair PDF is intentionally a best-effort, beta-style flow. It can often recover mildly broken or partially corrupted files, but it is not a guarantee for severely damaged PDFs where the underlying data is lost.
When a direct rebuild is not possible, the tool can reconstruct the export from readable pages, which may produce a flatter, more image-like result than the original. The goal is to preserve usable content, so keep the original file in case you want to try other recovery options too.
