Frequently Asked Questions
What is the difference between character diff and line diff?
Line diff compares text line by line — changes are shown at the line level. Character diff compares character by character within lines, highlighting the exact changed characters. Character diff is more precise for small edits.
Can I use this to compare code?
Yes. Paste any two versions of a file — code, config, or prose — and the tool highlights every addition and removal. The result is similar to what git diff shows.
What happens with whitespace-only changes?
Whitespace differences (extra spaces, trailing whitespace) are detected and highlighted. You can optionally ignore whitespace to focus on content-level differences only.
