HTML to Image Converter
Paste an HTML/CSS snippet, preview it live, and download it as a PNG
Live preview (export target)
How the HTML to Image Converter works
Paste any HTML markup and CSS rules into the two editors on the left — the panel on the right renders them live, exactly as a browser would, using an isolated preview element. When you click Render PNG, that same preview node is captured pixel-for-pixel using the html-to-image library and turned into a downloadable PNG file, at 1x, 2x, or 3x resolution for crisp retina output.
This is useful for generating social cards, email-safe graphics, code snippet screenshots, UI mockups, or any other design you want to freeze as a static image. Everything happens entirely in your browser — your markup, styles, and the rendered image never leave your device or touch a server. Toggle a transparent background if you need a PNG with alpha instead of a solid fill, and use the width presets to control how wide the exported canvas is.

What this tool is used for
- Exporting a styled snippet as a PNG for a slide or a post.
- Producing an image of a component for documentation.
- Rendering a snippet at 2x or 3x for a high-density display.
- Producing a graphic from markup rather than a design tool.
- Capturing a layout without taking a screenshot of a whole page.
Frequently Asked Questions
- How is HTML turned into an image?
- The markup is serialised into an SVG `foreignObject`, drawn to a canvas, and exported. That is the only path a browser offers without a screenshot API — and it explains every limitation, because `foreignObject` renders under stricter rules than the page does.
- Why do my images not appear in the output?
- Because the canvas is tainted by cross-origin content unless it is CORS-enabled. An `<img>` from another domain without `crossorigin` makes the export throw or produce a blank area, which is a security boundary rather than a bug.
- Why do the fonts come out wrong?
- Because a `foreignObject` cannot fetch an external font — it needs the font embedded as a data URI in the inlined styles. Anything loaded by `@font-face` from a URL silently falls back to a system font in the export while looking correct on the page.
- Should I use this instead of a server-side renderer?
- For a quick client-side export, yes. For anything that must be reliable — an OG image, a PDF, a report — a headless browser on the server renders the real page with real fonts and no `foreignObject` restrictions, which is why that is the production approach.
- How do I get a sharp image on a high-DPI screen?
- Render at a multiple of the layout size — scale the canvas by 2 or 3 and apply the same factor as a transform. Exporting at CSS pixel dimensions produces something that looks correct in the browser and soft everywhere it is later displayed.
Common errors and gotchas
- Referencing external fonts or images, which may not load in time for the capture.
- Exporting at 1x and finding the result soft on a high-density display.
- Using an image for text anyone will need to copy or search.
- Omitting alt text when the image ships, which excludes screen-reader users.
- Assuming the render matches every browser, when the capture uses this one's engine.
