Frequently Asked Questions
What is 'Sort Lines' useful for?
Sorting lines is incredibly useful when comparing list-based files like .env configs, JSON arrays, or dependency lists where the order doesn't matter, but you want to see if any items are missing.
How does 'Ignore Case' work?
When enabled, the tool treats 'Apple' and 'apple' as identical. This helps you focus on actual content changes rather than minor capitalization differences.
Can I save the comparison result?
Yes! Click the 'Export Report' button to download a nicely formatted HTML file containing the color-coded diff, which you can share with your team.
What is differences between Inline and Split view?
'Inline' shows both texts merged with highlights. 'Split' puts them side-by-side, which is great for visualizing structural changes.
Does it work with code files?
Yes! The 'Line' mode combined with Split View is excellent for code reviews.
Is there a limit on file size?
Since processing happens in your browser, the limit depends on your computer's memory. Typically, texts up to several megabytes work smoothly.
Is my data private?
100%. Your text is processed locally in your browser and never sent to any server.
How do I swap the inputs?
Click the 'Swap' arrow icon in the toolbar. Useful if you pasted the older version in the 'Modified' box by mistake.
What do the colors mean?
Red text means it was removed. Green text means it was added. Standard diff colors.
Is this tool free?
Yes, completely free diff checking with no hidden costs.
