About Text Compare

What is Text Compare?

Text Compare is a free online text comparison tool (text diff checker) that highlights exactly what changed between two versions. It shows added, removed, and modified lines in a familiar GitHub-style diff view, making it easy to compare text, compare code, or compare documents.

How It Works

1. Paste your original text on the left and your changed text on the right, or drag and drop a text file into either side.
2. Choose options like split vs. unified diff, context lines, ignore whitespace, and ignore case.
3. Review changes with line-by-line highlighting, then copy or download a unified diff patch.

Why Use Text Compare?

1. Fast text comparisons: Instantly compare two text blocks, code snippets, or config files.
2. GitHub-style diff: Split and unified views with readable line numbers and highlights.
3. Smarter matching: Options to ignore whitespace and case reduce noisy diffs.
4. Private: The diff is generated locally in your browser; no uploads required.

Common Use Cases

1. Compare two text files (e.g., .txt, .md, .json, .env) to find differences quickly.
2. Compare code changes before a deployment or code review.
3. Compare drafts of an article, email, policy, or documentation update.
4. Verify nothing important was removed or added when copying between systems.
