Code screenshots are everywhere: in tweets, LinkedIn posts, slides, tutorials and README files. A clean, colorful snippet looks far better than a crooked screenshot of your editor. The Code to Image Converter above turns any code into a polished image with syntax colors, an editor-style window and a background of your choice. You can export it as PNG, JPG, WebP or SVG. Everything runs in your browser, so your code is never uploaded.

How to Use the Code to Image Converter
- Paste your code. Add it to the code box, or click Try Sample to see an example for the selected language.
- Choose the language. This controls the syntax colors. Pick it yourself, because the tool does not guess.
- Pick a theme and background. Choose an editor theme, then a gradient or solid background. Use Transparent if you want no background.
- Adjust the details. Set the padding and font size, add a file name as the window title, and turn line numbers and the shadow on or off.
- Check the preview. The preview updates as you type.
- Export. Choose a format and scale, then click Download Image or Copy as PNG.

Choosing the Right Export Format
| Format | Best for | Good to know |
|---|---|---|
| PNG | Social posts, slides and documents. | Lossless and sharp around text. Supports transparency. The safest choice. |
| JPG | Places that only accept JPG. | No transparency, so a transparent background becomes white. Text edges can look slightly soft. |
| WebP | Blog posts and websites. | Usually smaller than PNG. Some browsers, such as Safari, cannot create WebP files, so the option is disabled there. |
| SVG | Websites, print and anything that must scale. | Stays sharp at any size and keeps the code as real text. The font depends on the viewer's device. |
Scale sets how many pixels the image has. Use 2x for most posts, because it stays sharp on high-resolution screens. Use 3x or 4x for large slides or print. Very large images may hit a browser limit, and the tool then lowers the scale and tells you. For more on picking formats, read our guides on WebP vs PNG and the Complete Guide to Image Optimization.
Tips for Better Code Images
- Keep it short. Show only the lines that matter. Around 10 to 20 lines is easy to read in a social post.
- Use a readable font size. 14 to 16 works for most cases. Go larger if the image will be viewed on a phone.
- Choose contrast. Dark themes on a bright gradient look great. Use a light theme for documents and print.
- Add a file name. A title such as
app.jsgives readers context at a glance. - Remove secrets. Never share API keys, passwords, tokens or private URLs in a screenshot.

- The highlighter is simplified. It handles common syntax well, but it is not a full language parser. Unusual constructs, such as regular expression literals or nested template strings, may be colored imperfectly.
- You choose the language. The tool does not detect it automatically.
- Fonts depend on your device. The image uses a system monospace font, such as Menlo, Consolas or a similar one. The look can vary between computers.
- Long lines are not wrapped. The image becomes wider instead. Break long lines in your code first.
- Line limit. The tool shows up to 400 lines. For longer code, split it into several images.
- Copy as PNG depends on your browser. If copying is not supported, use Download.
Frequently Asked Questions
Is the Code to Image Converter free, and is my code uploaded?
It is free and needs no signup. Your code is turned into an image in your browser and is never uploaded to a server.
Which format should I choose?
Choose PNG for most uses, because it keeps text sharp. Choose WebP for smaller files on a website, and SVG when the image must scale or when you want the code kept as text.
Why is the WebP option disabled?
Your browser cannot create WebP files from a canvas. Safari is one example. Use Chrome, Edge or Firefox, or export as PNG or JPG instead.
Can I get a transparent background?
Yes. Choose the Transparent background and export as PNG, WebP or SVG. JPG does not support transparency, so it uses a white background.
Why do my colors look different from my editor?
The themes are inspired by popular color schemes, and the tool uses its own simplified highlighter. Editors use full language parsers, so some tokens may be colored differently.
Is it safe to use my private code?
The tool does not send your code anywhere. Still, check the final image before you share it, and remove secrets such as keys, passwords and private addresses.
Final Thoughts
A good code image is short, readable and safe to share. Pick a clear theme, keep the snippet small, export at 2x, and always give readers the code as text too. A few seconds of polish makes your tutorials and posts look far more professional.
