Code to Image Converter

Turn a code snippet into an image you can share in a tutorial, presentation or post. This free code to image converter lets you choose basic syntax highlighting, adjust the layout and download PNG or SVG files. Your code stays in your browser as text, with no login, software installation or upload for conversion.

How to turn code into an image

1. Paste your snippet. Replace the example in the Code field with the text you want to show.
2. Choose highlighting. Select JavaScript, Python, JSON or HTML, or choose Plain text to keep the text unhighlighted.
3. Set the layout. Adjust the image width and font size. Choose a background colour and decide whether to wrap long lines or show line numbers.
4. Choose the PNG resolution. Use the 1×, 2× or 3× multiplier to control the exported PNG dimensions.
5. Click Generate code image. Check the preview, then download code-snippet.png or code-snippet.svg.

The tool renders pasted code as text. It does not execute JavaScript, run Python or load the HTML as a web page. Choosing a highlighting language changes the colours, not how the code behaves.

Make your code snippet easy to read

Start with a short example that shows the point you want to explain. A small, readable snippet usually works better in an image than an entire source file. Remove unrelated lines before generating the result.

For example, you could paste this JavaScript snippet and select JavaScript highlighting:

const message = 'Hello, world!';
console.log(message);

Use the font-size setting to keep the text readable where you intend to display the image. A larger export does not help if it is then squeezed into a narrow column. Line numbers are useful when your accompanying explanation refers to particular lines; switch them off when they add no useful context.

Long lines can wrap onto additional visual rows. If wrapping is disabled and a line will not fit, the tool reports an error instead of silently clipping it. Increase the image width, reduce the font size or enable wrapping. Tabs are displayed as four spaces.

PNG or SVG: which should you download?

PNG is a raster image with the appearance rendered by your browser. Use it when you want the displayed text and colours captured in a fixed image for sharing.

The PNG resolution multiplier increases the pixel dimensions without changing the logical layout. For example, a logical width of 960 pixels exports at 1,920 pixels wide with 2× selected, or 2,880 pixels wide at 3×. Higher multipliers also increase the total pixel count and can reach the output limit sooner.

SVG exports the layout with text elements rather than converting every character into a bitmap. The SVG uses a monospace font available on the device opening it, so letter shapes and spacing can differ between devices. Fonts are not embedded. The PNG multiplier does not increase the SVG’s logical dimensions.

Highlighting, colours and supported languages

The converter provides basic lexical highlighting for JavaScript, Python, JSON and HTML. It colours recognised text patterns rather than performing full language parsing or checking whether your program is correct. Plain text is useful for other languages, terminal output or snippets where you do not need highlighting.

You can choose the background colour. The tool selects a light or dark text palette based on that background, with separate colours for recognised keywords, strings, numbers and comments. Check the preview before downloading, especially when choosing a background close to the palette’s switching point.

Text uses your device’s monospace fallback font. Unicode characters depend on the glyphs available on your device, so review any specialist symbols or non-Latin text in the result.

Input and output limits

Use a nonempty snippet of up to 30,000 characters and 500 source lines. Image width can be set from 320 to 2,400 logical pixels, with font sizes from 12 to 36 pixels.

Output is limited to 16 megapixels and 16,000 pixels high. Wrapped lines can make the image taller even when the source contains fewer than 500 lines. If the result is too large, shorten the snippet, lower the PNG multiplier or adjust the layout.

The converter runs locally in your browser and does not require an account. When publishing an image of code, include a text version alongside it where practical so readers can copy the example and access its contents without relying on the image alone.
