About this compare pdf tool

Choose text comparison or visual page comparison. Text mode exports changed page text. Visual mode renders up to 20 pages per document, compares pixels and exports original, revised and red-highlighted images with a report. Pages are compared by index, without automatic alignment; layout shifts can create large differences.

When to use this tool

Review revised documents using changed text or highlighted pixel differences.

Get started in three steps

  1. Choose your PDF files from your device.
  2. Choose the original first and revised version second. Text mode needs selectable text; visual mode also works on scanned pages.
  3. Select Compare PDF, review the result and download your file.

A practical example

Choose an original contract draft first and its revision second. Use text mode for wording changes, or visual mode when stamps, scans or layout differences also matter.

Check the result

Inspect the changed-page text or the original/revised/highlighted images. Pages are paired by index; adding a cover to one file can make all later pairs appear different.

If the result is not right

The tool does not automatically align shifted pages or decide which change is legally important. Reconcile page order before visual comparison and read the source documents around each difference.

Before you download

Why can a small layout shift create many differences?

Visual comparison matches pages by index without automatic alignment. A shifted paragraph can change many pixels. Review the original and revised images alongside the report.
