Code to Image

Code to Image keeps the source inside the image instead of separating an editor from a preview. Click the code card and type. Syntax colors, dimensions, and export settings update at the same time, so the working view stays close to the downloaded result.

Select the language before choosing syntax colors. The language controls how keywords, strings, numbers, comments, functions, and types are recognized. Plain text preserves the source without assigning token colors. The tool highlights syntax but does not run, compile, or validate the program.

Whitespace is part of the image. Tabs, indentation, blank lines, and long expressions affect its height and readability. Clean the snippet in an editor first if it needs automatic formatting or lint fixes.

Syntax colors and window appearance are independent controls. A color set decides how code tokens are drawn. The dark and light switch changes the code window surface, foreground, border, and supporting text. This separation gives you more combinations than a single fixed theme.

Check contrast at the size where the image will be published. A bright token color that reads clearly in the editor may become faint after a large image is reduced inside a slide or documentation column. Mono provides a restrained option when color would compete with the surrounding design.

The window header can show a short filename and familiar control dots. Remove it when the destination already identifies the file. Line numbers work well for reviews and tutorials that refer to specific lines, but short decorative snippets are often clearer without them.

Background presets add a color field around the code window. Hide the background to export only the window on a transparent SVG or PNG canvas. Window shadow remains optional, which helps the card sit naturally on either flat layouts or layered presentation slides.

Padding controls the distance between the background edge and the code window. Image width controls the full export canvas. If the code feels cramped, increase the width before reducing the font. A wider image usually preserves readability better than smaller text.

Long unbroken lines can force horizontal scrolling while editing and may be clipped in the exported card. Break the expression at a meaningful boundary, shorten repeated values, or choose a wider canvas. The tool will not wrap code automatically because wrapping can change how a snippet is understood.

PNG creates a raster image that works in presentation software, chat applications, social platforms, and document editors. Choose 1x for the exact canvas dimensions, 2x for a sharper general-purpose export, or 3x when the image will be cropped or placed on a high-density display.

SVG keeps the code card as a vector document. It stays sharp when scaled and is useful in browsers, design tools, and documentation pipelines that accept SVG. The export includes its colors and layout, so it does not need an external theme file or web font request.

Some SVG importers have limited support for foreignObject, which is used to preserve highlighted multiline code. Test the SVG in the destination application. If it appears blank there but works in a current browser, download the PNG version for that workflow.

A code image is useful for presentation, but it should not replace source text when readers need to copy, search, edit, or run the example. Pair the image with a code block, repository link, or downloadable file in technical documentation.

Write alternative text that explains what the snippet does. Do not try to place every character in the image description. A short description such as a TypeScript function that validates an email address gives screen-reader users the purpose, while the nearby text version supplies the full source.

Remove API keys, customer data, internal URLs, and private repository details before creating the image. Processing happens in the current browser tab, but the downloaded file, clipboard, screenshots, browser extensions, and destination document can still expose its contents.

The editor accepts up to 50,000 characters and 300 lines. Those limits keep live highlighting and image generation responsive. A complete source file usually makes a poor graphic anyway. Select the smallest section that carries the idea readers need.

Before downloading, check the selected language, filename, line breaks, window mode, and image dimensions. Then view the exported file outside the browser tool. This final check catches scaling, cropping, font substitution, and SVG importer differences that the workbench cannot predict.

If PNG copying is unavailable, use Download PNG. Clipboard image support varies by browser and permission state, while file download works more consistently. Reset restores the sample and every original image setting.
