Frequently Asked Questions
Is the text diff checker really free?
Yes, our text diff checker is completely free to use with no hidden costs, watermarks, or usage limits. All processing happens in your browser, so there are no server costs or API fees.
What diff modes are available?
Our tool supports three diff modes: line-level (compares entire lines), word-level (compares individual words), and character-level (compares individual characters). You can switch between modes to get the level of detail you need.
Can I export the diff results?
Yes! You can export the diff results as a TXT file (plain text) or HTML file (formatted with colors). The exported files include all differences with proper formatting and can be shared or saved for future reference.
Does it work with large texts?
Yes, our tool can handle large texts efficiently. However, for very large texts (over 100,000 lines), the processing may take a few seconds. All processing happens in your browser, so your text is never uploaded to any server.
Can I ignore whitespace or case differences?
Yes! Our tool includes options to ignore whitespace (spaces, tabs) and toggle case sensitivity. This is useful when comparing code or documents where formatting differences are not important.
