Compare two text files and see the differences side by side
Diff Checker helps you compare two text files or pieces of text and see the differences line by line. Paste your original text in the left box and the modified text in the right box, then click "Compare Texts" to see the differences highlighted.
Features: Side-by-side comparison, line-by-line highlighting, statistics showing additions (green), deletions (red), and unchanged lines (gray). Perfect for code reviews, document tracking, and configuration management.
Tips: Use the quick examples to test the tool. Green lines show additions, red lines show deletions, and gray lines are unchanged. You can swap texts, clear all fields, and compare different types of content including code, documents, and data files.
