Frequently asked questions
What do the colors mean?
Green indicates additions (new text), red indicates deletions (removed text), and unchanged text stays neutral. Some tools show modifications in yellow or orange.
Should I ignore whitespace when comparing?
For code, ignoring whitespace helps focus on logical changes. For formatted documents or poetry, whitespace might be significant. Choose based on what differences matter to you.
Can I compare entire files?
Yes, paste the contents of any text files. For very large files (10,000+ lines), processing may take a moment. For binary files, use dedicated diff tools like git diff.
