Step by step

Compare PDF Files: step by step

Compare two PDF versions page by page and see every change highlighted side by side. Free online PDF comparison, no watermark, no signup.

  1. 1

    Add both versions

    Drop the original in the first slot and the revised file in the second — the order matters, because the report reads "original → revised".

  2. 2

    Run the comparison

    Both files must carry a text layer. If a file is a scan, run OCR first; the comparison needs words, not pictures.

  3. 3

    Read the report

    Every change is named and located — wording, numbers, inserted or removed blocks and pages that moved — with the key changes first.

Private and short-lived: every upload is erased automatically 72 hours after you last open it.

What the other tools do

Flip

Mirrors pages horizontally or vertically — the fix for artwork printed back to front, a transfer sheet, or a scan made through the back of the paper.

Split in half

Cuts two-page spreads into single pages: a scanned book spread, an A3 sheet that should read as two A4 pages, or a form printed two-up. The cut follows the page's own shape unless you force a direction.

N-up

Places several pages on one sheet — 2, 4, 8, 16 or 32-up — with a readable order and a sheet size you choose. It is the print-saving layout for handouts, proofs and booklets.

Resize

Changes the paper: scale every page to a new size (A4, Letter, Legal and the rest), add margins around existing content, or shrink the file.
