Frequently asked questions
Does this compare words or lines?
It compares line by line first, then highlights word-level changes within modified lines.
Can I ignore whitespace changes?
Yes. Enable "trim lines" to ignore leading/trailing whitespace, or "ignore empty lines" to skip blank line differences.
Is there a size limit?
The tool handles texts up to several thousand lines. Very large files may take a moment to process.
