Buddy’s illustration: Original and revision → Side-by-side review. Your document’s result depends on its content and settings.

Follow these steps

  1. Choose the supported source file or files from your device.
  2. Choose two PDFs and inspect corresponding pages side by side.
  3. Review differences visually, including dates, numbers and missing pages.

The document and the intended outcome

Open an original and revised report side by side. Inspect matching pages, compare headings and changed paragraphs, then check page counts so inserted pages do not shift your comparisons.

Make this example work for your file

For revised terms, compare matching sections rather than assuming the same PDF position contains the same paragraph. An inserted page can shift every later page without changing their actual content.

Choose only the settings this case needs

Add the intended two versions in a clear order. Match zoom and corresponding positions, and keep a short list of differences as you review.

When the example needs a different approach

Zoom into the relevant area and check source text when possible. Use a dedicated text-diff workflow for exhaustive wording comparison.

Check the result

This is a comparison workspace, not guaranteed automatic semantic or legal difference detection.

Keep the original. When this task produces a file, reopen the download in the application where you will use it and inspect the affected pages. An illustration explains the operation; it is not a recorded processing test.

Practical tips

  • Add the intended two versions in a clear order. Match zoom and corresponding positions, and keep a short list of differences as you review.
  • One version may contain an inserted or removed page. Align by headings or content instead of assuming page 4 matches page 4.
  • Zoom into the relevant area and check source text when possible. Use a dedicated text-diff workflow for exhaustive wording comparison.
