Privacy-First Ad-Free Online Diff Tool

Paste your text into the two text boxes below to see the difference.

Compare mode


      

Find differences between two text files.

Paste your file contents into the two input fields to compare.


🫆 Privacy first: this website doesn’t track you; your input data never leaves this browser.


The diff checker compares the text in both fields and returns the comparison result.

The text in the left input will be the original file for comparison. The text from the right input will be the compared text.

Highlighted in green is anything new found in the compared text file but not present in the original text.

Highlighted in red is anything that is present in the left input but found to be removed from the right.

Play around with the compare modes: compare by characters, words, lines or git-like patch.

Longer files might freeze the tab for some time, especially in char compare mode.
