Case Insensitive Text Compare

Compare two texts ignoring case, line by line.

PrivateBoth texts are compared on your device and never uploaded.
Original
Changed
Differences

Capitalization changes can hide real edits, or look like edits when nothing meaningful changed.

Case Insensitive Text Compare ignores case by default so only substantive differences are highlighted, line by line.

How to use Case Insensitive Text Compare

  1. Keep Ignore case enabled, then paste the original and the changed versions.
  2. Add Ignore whitespace if spacing differences should also be skipped.
  3. Review the highlighted real changes, then copy the result.

Use cases

Good to know

Case Insensitive Text Compare lowercases both sides only for matching, so lines that differ purely in capitalization are treated as equal while the output still shows your original text. It compares line by line and runs entirely in the browser.

Frequently asked questions

Why is Ignore case on by default?

Because this tool targets case-insensitive review, so trivial capitalization differences do not get flagged as changes.

Does it still show my original capitalization?

Yes. Case is ignored only while matching lines; the highlighted output preserves the exact characters you pasted.

Can I also ignore spacing differences?

Yes. Turn on Ignore whitespace and differences in spacing are skipped alongside case.
