FAQ
- When should I use a text diff tool?
- Use a text diff tool when you need to compare two versions and identify exactly what changed. It is especially helpful for code reviews, config checks, and document revisions.
- Can I ignore whitespace or letter case differences?
- Yes, those options help reduce noise from formatting-only edits. Ignoring non-semantic changes makes functional differences easier to review.
- Can I copy diff output for pull requests or reviews?
- Yes, you can copy generated diff output and paste it into reviews, issues, or team chat. This is useful when you need to discuss changes outside a full Git workflow.
- Will this tool handle very large files?
- It handles typical code and document sizes well, but extremely large inputs may feel slower. Performance depends on browser resources because comparison runs client-side.
