Generate beautiful code screenshots with one click, supporting multi-language syntax highlighting and customizable themes.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Enter or paste code, select a language for syntax coloring, choose a visual theme, and preview it as a code card. You can edit the window title, toggle decorative window controls and line numbers, and adjust padding from 0 to 128 px and text size from 10 to 28 px. The result is a PNG image, not an executable or formatted source file. Syntax colors depend on choosing a language that matches the snippet; an unsupported construct may not receive the expected coloring.
Long lines and larger text make the image wider. More padding adds space around the snippet but also enlarges the overall card. A short, focused example is usually easier to read in a slide or article than a full source file. Preview the result at the size where people will view it, and check indentation and line numbers before export.
A PNG preserves the appearance as pixels; readers cannot select, search, or reliably copy the code from it as they can from text. W3C’s image guidance recommends a text alternative that conveys the words when an image contains important text. See the W3C Images Tutorial.

Guide
Follow the workflow and verify inputs and outputs with practical examples.
Paste the portion of code you intend to show. Remove secrets, access tokens, private URLs, and personal data before using the preview.
Choose the matching language, then select a theme and enter a concise title such as a filename or topic.
Set padding and text size, then turn line numbers or the window decoration on or off to suit the context.
Review the preview for complete lines, indentation, and readable text. Download the PNG, or use copy-image when supported by the browser; if image copying is unavailable, the action downloads the image.
For a tutorial, show only the few lines that demonstrate the concept and include the original code as selectable text alongside the image.
Use cases
See how the tool fits into real work and everyday tasks.
Authors can style a short code sample to match an article or lesson, while keeping a copyable code block nearby for readers who want to try it.
Presenters can add a short title and line numbers to help an audience follow a few relevant lines on a slide. Test text size from the back of the room or on the expected screen.
Instructors can highlight a small example in a consistent theme. Provide the source text separately so students can copy, search, and adapt it.
Q&A
Find concise answers to common questions and confusing cases.
No. It makes a styled image from the text you provide. It does not execute, compile, lint, or check the program’s behavior.
Check that the selected language matches the snippet. If the language or syntax feature is not supported by the available highlighter, some text may appear without the expected colors.
The export is PNG, and there is no fixed width or height input. Adjust the font size and padding, then inspect the resulting image in your target layout.
Not as they can with source text. Include the code as selectable text nearby, and provide a suitable text alternative if the image itself conveys important information.
Notes
Review scope, result limitations, and important precautions before use.
Check both the code and the title for passwords, tokens, customer information, private hostnames, usernames, or local file paths before export. Treat the PNG as a visual companion rather than the source of record: keep important code in readable text so it remains selectable, searchable, and usable with assistive technology.
