What is a Diff Checker?
A "diff" checker is a powerful tool used to compare two pieces of text and highlight the exact differences between them. The term "diff" is short for difference. Our online tool analyzes two texts line-by-line and visually shows you which lines were added, which were removed, and which remain the same. It's an essential utility for developers, writers, editors, and anyone who needs to track changes between two versions of a document or file.
How to Use Our Online Diff Tool
- Paste your original text into the "Original Text" box on the left.
- Paste the new or modified text into the "Changed Text" box on the right.
- The "Differences" view below will automatically update, showing you a line-by-line comparison.
- Lines highlighted in red were removed. Lines in green were added.
- Use the settings to toggle case-sensitive comparison on or off.
