FREE BROWSER-BASED CONVERTER
HTML to PNG converter for code and .html files.
Paste HTML and CSS or load a self-contained .html file, choose the canvas size, preview it safely, and download a crisp PNG. Your code is processed in this browser—not sent to ToolMerit.

HTML TO PNG CONVERTER
Paste code or upload an HTML file.
This converter is designed for snippets, cards, diagrams, and simple layouts. It deliberately blocks scripts and removes remote resources before rendering.

Your rendered PNG will appear here.

Local by design. Your pasted code and generated image stay in this browser. Scripts are removed and not executed.
KNOW THE BOUNDARY
HTML files and snippets work; webpage URLs do not.
The useful distinction is simple: this tool turns code you paste or load from a local .html file into an image. It does not visit a live webpage, wait for an application to load, or reproduce a browser session.

- Full-page website screenshots
- Pages that depend on JavaScript
- Authenticated dashboards

HOW CONVERSION WORKS
How to convert HTML to PNG locally.
Paste or load
Add markup or choose an .html file.
Clean
Scripts and remote resources are removed.
Render
A sandboxed SVG snapshot is drawn to canvas.
Download
The canvas is encoded as a PNG file.
The safe preview helps you inspect the sanitized result before rendering. The downloadable image uses your chosen size and scale; a 1200 × 630 canvas at 2× becomes a 2400 × 1260 PNG.
OUTPUT CONTROLS
Choose dimensions for the destination.
Link and social cards
A common landscape starting point when you need room for a headline, a short supporting line, and one visual idea.
Square graphics
Useful for square feed layouts, compact quote cards, simple announcements, and reusable content blocks.
Pixel density
Scale changes the downloaded pixel dimensions without changing the design canvas. Higher scale creates a larger file and needs more browser memory.
Background control
Use a solid canvas when the PNG must stand alone, or enable transparency when the destination supplies its own background.
LIMITS THAT MATTER
Why a preview can differ from a webpage.
JavaScript is intentionally blocked
Interactive components, charts, web apps, and client-side templates will not run. Convert their final static HTML instead. See MDN’s iframe sandbox reference for the underlying browser controls.
Remote resources are removed
External images, stylesheets, fonts, and CSS URLs can make browser canvas export unsafe or unreliable, so this converter removes them. MDN explains the relevant cross-origin canvas restrictions.
Browser rendering still matters
The export relies on SVG foreignObject and Canvas support. Very complex CSS or extremely large outputs may fail or render differently between browsers.
Input size is deliberately bounded
Width and height are limited to 100–2400 CSS pixels and scale to 1×–3×. The tool also blocks oversized pixel combinations to avoid freezing the tab.
TROUBLESHOOTING
Fix the output before adding complexity.
Check that the HTML field is not empty and that the visible content does not depend on a script, iframe, form control, or remote stylesheet.
Use a base64-encoded data image inside the HTML. Remote src values and CSS url() references are stripped.
Remote web fonts are unavailable. Use a system font stack such as Arial, Georgia, or system-ui for predictable output.
Increase the canvas height or reduce padding and font size. The converter captures the fixed canvas, not an automatically expanding page.
Try 1× or 2× scale, reduce the dimensions, close memory-heavy tabs, and render again.
Update to a modern browser with Canvas, Blob, SVG, and foreignObject support, or try a current Chromium-based browser.
HTML TO PNG FAQ
HTML file, URL, privacy, and output questions.
These answers define what the tool actually does, so you can choose it for the right job.
Can I convert a .html file to PNG?+
Yes. Choose an .html or .htm file up to 500 KB. The tool extracts the document body and inline style blocks into the editable fields, then renders locally. It does not resolve neighboring asset folders or external resources.
Can I convert a webpage URL to PNG?+
No. A URL screenshot requires a browser or server to visit the page, load its resources, and often execute JavaScript. This tool renders only the self-contained code you provide.
Does the converter run my scripts?+
No. Script elements, event-handler attributes, embedded frames, forms, and other executable or interactive elements are removed before preview and export.
Is my HTML uploaded or stored?+
No. Conversion happens locally in your current browser tab. ToolMerit does not receive or store the HTML, CSS, preview, or PNG created in this tool.
Can the PNG have a transparent background?+
Yes. Enable Transparent in output settings. Remember that any background declared inside your own HTML or CSS will still appear.
Why are remote images and fonts not included?+
Browsers restrict exporting a canvas that contains cross-origin content without the right permissions. Removing remote resources keeps the workflow private and reduces failed downloads.
KEEP BUILDING
Put the image into a useful workflow.
