What is the Git Diff generator?
A git diff image tool colors added and removed lines, hunk headers and file paths so a change is reviewable at a glance. Drop a focused diff into a pull request, a code review or a teaching thread without sharing your whole screen.
Codeshot is free and runs entirely in your browser — no account, no watermark, and nothing you paste is uploaded. Export a retina PNG or a scalable SVG, or copy the image straight to your clipboard.
When to use it
- Pull requests and code reviews
- Before/after teaching examples
- Changelogs and release notes
- Refactor and migration write-ups

Git Diff — frequently asked questions
Which diff formats work?+
Unified diffs — git diff, git show and standard patches. Added (+), removed (−), hunk (@@) and header lines are all styled.
Can I show a multi-file diff?+
Yes — paste as many files and hunks as you like; the window grows to fit the change.
What can I export, and is it free?+
Export a high-resolution PNG or a scalable SVG, or copy straight to your clipboard. Codeshot is completely free — no account, no watermark, no limits.
Do I need an account or any software to install?+
No. Codeshot runs entirely in your web browser — there is nothing to download or install, and no sign-up, login or email is required. Open the page, paste your content and export.
Can I use the exported images commercially?+
Yes. You keep all rights to the content you paste and the images you create, and you can use them in commercial blog posts, courses, slides, documentation and social media at no cost. There is no watermark on any export.
Can I customize the theme, font, background and size?+
Yes. Choose from a dozen real editor themes (Dracula, Night Owl, One Dark, GitHub and more), premium self-hosted fonts, gradient, solid or transparent backdrops, light or dark window modes, and adjustable padding, font size, shadow and window controls.
Does Codeshot work on mobile and in every major browser?+
Codeshot works in modern browsers on desktop and mobile, including Chrome, Firefox, Safari and Edge. A larger screen makes fine-tuning the frame easier, but you can create and export an image from a phone or tablet too.
