If you like the service, there is a paid desktop version with more features.

What is Diffchecker?

Diffchecker is a data comparison tool that calculates and shows the differences between file contents. Diffchecker is commonly used to illustrate differences between two versions of the same file.

How to use Diffchecker?

To use diff checker, simply copy and paste the contents of the files into the input boxes and the difference will be generated automatically. If there is a difference, it will be marked appropriately. The marking operates from left to right, so if a word is removed from the left side, it is shown in red, while if a word is added to the right side, it is indicated as added and shown in green.

You get a real-time summary of changes. Each document has a separate margin that identifies changes within the entire document. By clicking on the margin, you can quickly scroll to the change.
