Double PDF 2.0

Improve PDF management on your computer. Open files with double-sided pages and structure their data properly to simplify browsing, copying, editing, and conversion. Search for differences between two copies of the same page, track individual strings, etc.

Double PDF is a lightweight and small application for viewing and comparing PDF documents. It enables you to flip through two PDFs at once, search for differences between them, and compare them side-by-side by previewing their pages. It also has the option of viewing text differences using popular text editors such as BBEdit or Text Wrangler. The interface is available in English.
