Compare two texts and highlight added, removed, and changed lines.
Compare two texts side-by-side and highlight the differences. Added lines are shown in green, removed lines in red, and changed sections are highlighted inline. Useful for comparing code, documents, or any text content.
Text Diff Checker provides a quick, web-based method for comparing two blocks of text side-by-side without needing to install desktop software. It instantly highlights added, removed, and changed sections with color-coding, making it efficient to spot discrepancies in code, documents, or general text content. Because it is free and accessible directly in the browser, users can perform routine comparisons without friction.
Good to know: Very large texts or datasets may exceed browser performance limits for side-by-side comparison, and users requiring offline access or advanced version control features may need dedicated desktop software.
Quickly compare two versions of text or code to identify added, removed, and modified lines with side-by-side highlighting.
Access the Text Diff Checker tool
Navigate to the Text Diff Checker tool page to begin your comparison. The interface provides two distinct input areas for your original and modified content.
Paste your original text
Copy the initial version of your text or code and paste it into the left-hand input field. This serves as the base for the comparison.
Input the modified text version
Paste the updated or second version of the text into the right-hand input field. The tool will prepare to analyze the differences between both snippets.
Review the highlighted differences
Examine the side-by-side results where added lines appear in green and removed lines appear in red. Inline highlights will pinpoint specific character changes within modified lines.
