Comparison PDF is a free and powerful online tool for comparing PDF documents in multiple formats. It offers three distinct comparison views: Strike-through, Side-by-Side, and Graphical, each designed to make differences clear and easy to understand.

Using Comparison PDF is simple. Start by selecting your source file and the file you want to compare. Then, click ‘Compare’ to initiate the process. The application will analyze the text line by line, highlighting any differences between the two PDF documents. Our Graphical view adds a blue mask layer to pinpoint changes in both text and graphical content, while Strike-through highlights deletions, and Side-by-Side provides a direct layout for side-by-side review.

Our PDF comparison tool is case-sensitive, recognizing subtle text distinctions—like ‘Hello world’ versus ‘Hello World’—ensuring precise results. This is especially important when comparing documents where even minor text variances can carry significance.

This app makes it quick and easy to detect even minor edits between versions of your PDF documents, eliminating the need for time-consuming manual review.

Comparison PDF runs seamlessly on any popular operating system and browser, including Windows, macOS, Linux, and Android, so you don’t need to install additional software. Your documents remain secure; they’re stored temporarily for 24 hours and then deleted automatically. To remove files immediately after viewing results, click the ‘Delete’ button.

We are continually refining Comparison PDF to bring you the best experience. Your feedback is invaluable—let us know your thoughts through our website feedback form or social media groups.
