FAQ
- Does this diff ignore whitespace?
- Whitespace differences are treated like any other text. Switch to word mode for easier reading if spacing varies a lot.
- Can I export in unified diff format?
- Not yet. Download the annotated text and convert it with command-line tools if you need a specific diff format.
- How large can my input be?
- Browsers can handle moderately large texts, but performance may degrade past a few hundred kilobytes. For massive files use a dedicated diff application.
