How to use

Paste the original and revised text and compare by line or character. Ignore whitespace or line-ending differences only when they are irrelevant.

Navigate through changes and check deletions as well as additions. Do not sort meaningful ordered text merely to make the diff smaller.

line 1
line 2

line 1
line changed

Each input is limited to 1,048,576 bytes, output to 33,554,432 bytes, and processing to 5,000 ms. Input is never silently truncated.
