Here's how it works

Select the two files you want to compare and start the comparison. A few seconds later, you will see the differences between the two files.

Not only supports PDF

Your files do not necessarily have to be PDFs. This app supports all files that our system can convert to PDF. The conversion to PDF is done automatically.

Ease of use

PDF24 makes it as easy as possible for you to compare documents. You don't need to install or set up anything, just select your files.

Supports your system

There are no special requirements for comparing two files on your system. This app works with all major operating systems and browsers.

No installation required

You do not need to install any software. The files are compared on our servers. Your system does not require any special requirements.

Security is important to us

Our file comparison tool does not store your files longer than necessary. Your files and results will be removed from our server after a short time.
