Frequently Asked Questions
How does the diff comparison work?
Our tool uses a line-by-line comparison algorithm to identify differences between two texts. Lines that exist only in the original are marked as deletions (red), lines only in the modified version are additions (green), and unchanged lines are shown normally.
Can I compare large files?
Yes, you can compare large files. Your data is sent to our server for processing and immediately discarded after the comparison is complete. Performance is fast for most file sizes.
How is my data handled?
We collect only metadata (tool usage, data sizes, timing) - your actual data is never logged or stored.
Can I compare code files?
Absolutely. This tool works great for comparing any plain text including source code, JSON, XML, configuration files, SQL, and more. Just paste your code into both fields.
