How this tool works
Rebuild PDF: a practical guide
Parses the source pages and copies them into a new document, which can remove some broken document-level structures or unnecessary catalog data.
Steps to use this tool
- Select the problematic PDF.
- Attempt a rebuild of its readable pages.
- Open the new file and compare page contents with the original.
Tested example — 19 October 2026
The readable two-page fixture is rebuilt into a new two-page PDF.
Selected sample: sample.pdf (2421 bytes, 2 pages).
Measured output: sample-rebuilt.pdf — 2359 bytes; 2 PDF pages.
Test environment: Node + native canvas + actual site-ui.js form integration in LinkeDOM Representative sample; inspect your own output.
Check the result
Compare the rebuilt page count with the source and inspect images and text. Rebuilding is not proof that forms, attachments or signatures survived.
Files and privacy
The public tool processes selected documents in your browser. It does not send document bytes to a conversion server. The page and its bundled libraries still download from this website. Keep the original, use an up-to-date browser and inspect your output before sharing it. See the privacy policy for hosting and support information.
If processing fails
If the source cannot be parsed, this page-copy workflow cannot repair it. Try the producing application or a specialist recovery tool instead of treating an error as a repaired document.
