The best in security

Keep your files confidential and private – with Diffchecker Desktop they never leave your computer

How it works?

Since Diffchecker Desktop runs fully on your computer, it doesn’t have to communicate with our servers to create your diffs.

What this means is that there’s no way anybody else but you can view your sensitive data.

Use cases for Diffchecker Desktop with better security: taxes, legal documents, files with passwords and confidential code

Offline mode & better performance

Diffchecker Desktop runs offline which means you can use it wherever you are and save on your data plan.

As everything happens locally on your own computer, you also get significantly improved app speed.
