About This Tool

The Code Diff Checker provides a visual comparison between two snippets of code, highlighting added, removed, or modified lines with precision — essential for developers reviewing changes or merging code manually. It helps you spot subtle syntax differences that are easy to miss in a standard editor. This tool is completely free, secure, and requires no account or registration.

How to Use

1
Paste your original code into the left input panel.
2
Paste the modified version into the right input panel.
3
Differences are highlighted immediately — green for additions, red for deletions.
4
Click the download button to export the diff as a .diff or .patch file.

Frequently Asked Questions

Does the diff checker work for any programming language?

Yes. It performs a text-based diff, so it works with any language — code, JSON, YAML, plain text, or anything else.

How large can my code files be for comparison?

There is no strict limit. The comparison runs in your browser, so very large files may be slower on older devices.

Is this code comparison tool free?

Completely free with no account or file upload required.

What types of code can I compare?

You can compare any text-based code, including JavaScript, HTML, CSS, JSON, Python, and more. It works with any language for basic diff checking.
