Repair a PDF: step by step

Recover data from a damaged or corrupted PDF that won't open. Free online PDF repair tool, no signup.

  1. 1

    Upload the damaged PDF

    Drop in the file that will not open. Repair's door is a forgiving one — it takes documents other tools turn away, and if the preview engine cannot draw the file at all, the page simply says so and waits. Files are deleted after 2 hours.

    The workspace after a damaged upload — “This file cannot be previewed — it looks damaged. Repair will rebuild what it can.”
  2. 2

    Press Repair PDF

    One click runs the rebuild: a forgiving read first, then a deep scan for every page object if the file still resists. Their own caution sits above the button — the repaired PDF might not have all contents from the original file — so keep the source around.

  3. 3

    Download the rebuilt file

    The recovered document arrives on the ready page — previewed right there, page count included, waiting behind Download. One damaged last page comes back blank rather than sinking the whole file.

    The rebuilt document's first page in the preview — Quarterly Report, Section 1 — recovered content The ready page showing rp-damaged.pdf — 1.9 KB · 3 pages · deleted automatically after two hours — above the Download button
  • Made for broken files

    The upload takes what other tools refuse — even a PDF the preview cannot draw.

  • Two-stage rebuild

    A forgiving read first, then a deep scan for every page object if the file still resists.

  • Fresh structure

    Pages are copied into a cleanly rebuilt document instead of patching the broken one.

  • Wrecked tail handled

    A destroyed last page comes back blank rather than sinking the whole document.

  • Locked files redirected

    Password-protected? Repair spots it and points you to Unlock with the password first.

  • Private by default

    No account, no watermark — and every file is automatically deleted after 2 hours.

What the other tools do

Flatten

Fixes a document's state so it prints and shares the same everywhere: either only the form fields become part of the page, or the whole document is rendered flat at a resolution you pick.

Compress

Shrinks a PDF by re-encoding its images at the quality and resolution you choose, dropping multimedia and optionally optimising embedded fonts. Text stays text — only pixels are traded.

Edit PDF

The full editing workspace: retype existing text in place, add text, images, stamps, shapes, whiteout and signatures, draw highlights and freehand marks, and place links or form fields. Editing an existing line keeps its font, size and colour instead of replacing it with a lookalike.

Page Numbers

Numbers the pages in the format and position you pick, starting from any number — the narrow version of Header & Footer when numbering is all you need.
