4.3 Draftable: Best for Comparing Formatting
Draftable is a PDF comparison tool that helps you to see changes to text styles – like font, font size, bold and italics – as well as to the actual content. Differences are highlighted, and you can see every change together in one list. Click on a change that you want to check, and you’ll be taken to that point in the PDF file. However, Draftable doesn’t keep track of comments and annotations made by reviewers, so you’ll need to manually make sure all feedback has been met.

Soda PDF offers a free trial, and paid plans start at $7.97/month.
4.5 Diffchecker: Best Free Tool for Comparing Basic PDF Files
Diffchecker is a free online compare tool that’s ideal for quickly comparing short PDF documents. It’s fairly basic in functionality, and it converts your PDFs into plain text and breaks it down line by line before highlighting any differences. Diffchecker is not recommended for longer documents or if you have lots of comments to keep track of, but for a simple comparison of two PDF files, it’s a good free option.
Diffchecker is a free software. You can upgrade to Pro for $15/user per month or to Enterprise for $40/user per month, but these upgrades don’t provide much added value for document comparison.
