Changed PDF
PDF Compare checks the text content of two PDF documents and highlights exactly what's different between them - added text, removed text, and changed wording. It's useful for reviewing contract revisions, comparing two drafts of a report, or verifying that a "final" version matches what was actually agreed on.
Frequently asked questions
It compares text content - wording that was added, removed, or changed between the two documents. It is not a pixel-by-pixel visual comparison of layout or images.
It works best comparing two versions of essentially the same document (like a draft and a revision). Comparing two unrelated documents will just show a large amount of difference, which is technically accurate but not very useful.
Changed text is highlighted so you can quickly scan for what was added or removed between the two versions.
