Repair PDF

Fix a broken, scanned, locked, or slow-loading PDF in one pass. Recovers corrupt files, adds a text layer to scans, strips password restrictions, and optimizes for web.

All four repair passes are safe — they preserve the original page visuals. OCR adds an invisible text layer only if the PDF is scanned (no text layer detected). Linearize is recommended for any PDF you serve over the web. Unlock requires the actual PDF password.

Repair structuredefault

Rebuild the PDF's internal xref table and trailer. Fixes most 'won't open in any viewer' errors caused by partial downloads, bad copies, or file corruption.

Add OCR text layerdefault

If the PDF is scanned (no text layer), run Tesseract OCR to add an invisible text layer so it becomes searchable (Ctrl+F) and text-selectable. Skipped if a text layer already exists.

Linearize (Fast Web View)default

Re-save the PDF with the cross-reference table at the start of the file. The first page renders before the whole file is downloaded. Recommended for any PDF served over the web.

Unlock (remove password / permissions)

Strip the owner password (edit/print/copy restrictions). If the PDF also has a user password, supply it below so we can remove that too.
