Frequently Asked Questions
How does the Diff Checker work?
The Diff Checker uses a JavaScript library to compare the two texts you provide. It analyzes them character by character (or line by line, depending on the underlying algorithm) to find parts that have been added, removed, or remain the same. This comparison happens entirely within your web browser.
Is my text data safe and private?
Yes, absolutely. All text processing and comparison happen locally in your browser. Your text is never sent to our servers or stored anywhere. This ensures complete privacy and security of your content.
What do the colors in the difference view mean?
Text highlighted in green typically indicates text that has been added to the original version. Text highlighted in red with a strikethrough indicates text that has been removed from the original version. Text with no special highlighting is common to both versions.
Can I compare entire files?
Yes. While you can't upload files directly for a side-by-side file diff in the traditional desktop sense, you can use the 'Upload File' button associated with each text input area. This will load the content of your text files (e.g., .txt, .md, .html, .js) into the respective input fields for comparison.
How do I copy the results?
You can copy the original or changed text using the 'Copy' buttons beneath each input area. To copy the highlighted differences, use the 'Copy Diff' button. This will copy a plain text version of the diff, with additions and deletions usually marked or formatted for clarity, though the exact appearance may vary when pasted into different applications.
