Text Diff Checker Guide: Compare Two Texts and Find Differences
Comparing two versions of text to find differences is essential for code reviews, document version control, and tracking changes. Our free text diff checker makes this process simple. According to Wikipedia, a diff is a file comparison utility that outputs the differences between two files. It was originally developed for Unix and is now widely used in version control systems like Git.
What is a Text Diff?
A text diff (difference) shows the changes between two versions of text, highlighting what was added, removed, or modified. This is essential for code reviews, document version control, and tracking changes. The diff format was standardized in the Unix diff utility and is now used by version control systems worldwide.
Why Use a Text Diff Checker?
Common reasons to use a text diff checker:
- Code Reviews: Compare code changes before merging pull requests
- Document Comparison: Compare different versions of documents and track changes
- Content Editing: Track edits and changes in content revisions
- Debugging: Compare configuration files and identify changes
- Version Control: Understand what changed between versions
How to Compare Two Texts
Using our text diff checker:
- Visit the text diff checker page - no registration required
- Paste or type the original text in the first text area
- Paste or type the modified text in the second text area
- Select the diff format: unified (standard), context (with surrounding lines), or HTML (color-coded)
- Click "Compare Texts" to generate the diff
- Review the diff output showing added (green), removed (red), and changed lines
- Check the statistics for lines added, removed, changed, and similarity percentage
Key Features
Our text diff checker offers:
- Multiple Diff Formats: Unified diff (standard), context diff (with surrounding lines), or HTML diff (color-coded)
- Color-Coded Output: Easy-to-read visual comparison with color coding
- Statistics: See lines added, removed, changed, and similarity percentage

- Code Support: Works with any text content including code files
- Instant Comparison: Fast diff generation in real-time
Understanding Diff Formats
Different diff formats serve different purposes:
- Unified Diff: Standard format used by Git and most version control systems. Shows changes with context lines.
- Context Diff: Shows changes with surrounding context lines, making it easier to understand the context of changes.
- HTML Diff: Color-coded visual comparison perfect for presentations and documentation.
According to GNU Diffutils documentation, the unified format is the most commonly used format for showing differences between files. For text analysis, try our Word Counter tool.
Tips for Best Results
To get the best results with text diff checking:
- Use unified diff for standard code reviews and version control
- Use context diff when you need to see surrounding lines for better understanding
- Use HTML diff for presentations and documentation
- Check the similarity percentage to quickly assess how different the texts are
- Review statistics to understand the scope of changes
- Copy the diff output for documentation or sharing
