About

If you produce PDFs for publication, a PDF comparison tool can show you the exact differences between, say, the first printing, and your proposed second printing. This way you can easily spot unintended changes to the pagination. Also, you can save time by checking only those pages that have changed, rather than having to review the whole publication all over again. Statements and policies must always have the correct disclaimers and other legal information. When formats or policies change, it is vital that the changes are only those intended something easily verifiable with a PDF comparison tool. It is common to follow a paper trail of emails, memos, and so on, as part of an investigation. This trail will often include PDF documents. Using a PDF comparison tool will allow you to forensically observe the evolution of a document—perhaps revealing when critical changes were made.

About

Diffract is a purpose-built desktop diff tool that handles far more than plain text. A single app compares text, binary (hex view), images, PDFs, Word documents, Excel spreadsheets, ZIP/tar archives, and Git commits - all in a multi-tab interface. On top of the standard Myers diff, it offers Patience and Histogram algorithms per comparison, AST-based semantic diff that understands code structure (not just line changes), and automatic moved-block detection. It also runs fully headless as a CLI tool for use in CI pipelines. Licensing is a one-time purchase with no subscription, and validation happens entirely offline.
