Frequently Asked Questions
How does the Diff Checker work?
Paste two texts into the left and right panels. Click "Find Differences" and the tool compares them line by line, highlighting additions (green) and deletions (red).
Is my text stored or sent to a server?
No. The diff comparison runs entirely in your browser using JavaScript. Your text never leaves your device.
Can I compare code files?
Yes. The Diff Checker works with any text including source code (JavaScript, Python, Java), configuration files (JSON, YAML), SQL queries, and plain text documents.
Is there a file size limit?
Since it runs in your browser, it can handle texts up to several megabytes depending on your device memory. There is no server-side limit.
