HTML to PNG Converter
Turn HTML code into a downloadable PNG image. Paste markup or upload a file, preview it, and export a sharp screenshot instantly — all in your browser.
100% Client-Side Processing
Your HTML is rendered and converted entirely in your browser. Nothing is uploaded to a server.
Preview
For safety, <script> tags are disabled in the preview and export. Styling (CSS) and images render normally.

What is an HTML to PNG Converter?
An HTML to PNG converter takes HTML and CSS markup and renders it as a single raster image, ready to download, embed, or share — like taking a screenshot of code without opening a real browser tab.
It is useful for turning cards, banners, social previews, code snippets, or any styled web content into a crisp, portable image file without needing a design tool, a screenshot extension, or a server-side rendering service.
How it Works
- Add your HTML: Paste HTML/CSS directly, or upload an .html file.
- Preview it: The tool renders your markup live in an isolated preview at the capture width you choose.
- Choose image settings: Pick capture width, resolution (1x/2x/3x), and a transparent, white, or custom background.
- Convert and download: The preview is rasterized at full quality and packaged into a downloadable PNG.
Features
- Paste HTML or upload an .html file
- Live, WYSIWYG-style preview at real capture width
- Adjustable capture width in pixels
- 1x, 2x, and 3x resolution for crisp, retina-ready images
- Transparent, white, or custom background color
- Single full-height image — no pagination
- 100% client-side processing for privacy
Best Practices
- Use inline or embedded CSS: Put styles in a <style> tag or inline attributes so the preview renders exactly as intended.
- Use data URIs for critical images: Cross-origin images without CORS headers may fail to render — embed small images as base64 data URIs when possible.
- Pick a width that matches the target: Match the capture width to where the image will be used (e.g. 1200px for social cards, 600px for email graphics).
- Use transparent background for overlays: Choose transparent when the PNG will sit on top of another background, like a UI mockup or a logo.
- Test with the sample first: Load the sample HTML to see a working example before pasting your own markup.
Troubleshooting
Images are missing from the PNG
External images hosted on other domains without proper CORS headers cannot be captured. Use images from the same origin or convert them to base64 data URIs.
The background is not transparent
Make sure "Transparent" is selected under Background before converting — the "White" and "Custom color" options fill the canvas with a solid color.
Conversion fails or times out
Very large documents or complex CSS (heavy gradients, filters) can be slow. Try simplifying the markup or reducing the capture width.
Fonts look different in the PNG
The converter uses fonts available in your browser. Web fonts loaded via @font-face from external domains may not always be captured — use system fonts for guaranteed consistency.
Common Use Cases
- Social media cards: Design an Open Graph or Twitter card layout in HTML and export it as a shareable PNG image.
- Code and terminal screenshots: Style a code block or terminal output and export a clean image for docs or tweets.
- Email graphics: Turn a styled HTML banner or button into a static PNG for email clients that strip live HTML.
- UI mockups and badges: Export a small styled component with a transparent background to overlay on other designs.
- Blog and README images: Convert a formatted HTML snippet into an image to embed in Markdown documentation.
Frequently Asked Questions
Yes. Your HTML is rendered and converted entirely in your browser and is never uploaded to a server.
No. Script tags are disabled in the preview and export for safety, so interactive scripts will not execute.
Yes. Choose "Transparent" under Background to export a PNG with an alpha channel, ideal for overlays and logos.
Use 1x for standard screens, 2x for retina/high-DPI displays, and 3x for the sharpest possible output (larger file size).
You can paste a complete HTML document (with <html>, <head>, and <body>) or a smaller HTML fragment. Both are supported.
Images loaded from other domains without CORS support cannot be captured for security reasons in the browser. Use same-origin images or base64 data URIs instead.
No. Everything happens locally in your browser and the PNG is downloaded directly to your device.
