HTML to Image Converter
Convert HTML/CSS code or capture webpages as PNG, JPG, or WebP images. Fast client-side processing or high-quality server-side rendering.
How it works
Client-side processing is fast and private. Server-side offers better CSS rendering for complex layouts.

Processing Mode Guide:
Client-side (html2canvas)
Fast, private, works offline. Best for simple layouts and quick exports. Some CSS features may not render perfectly.
Server-side (Headless Browser)
Uses real Chrome browser for pixel-perfect rendering. Required for URL capture. Supports all modern CSS features.
Client-side vs. Server-side Rendering
This converter gives you two rendering engines, and the right one depends on your content. In client-side mode, your pasted HTML is rendered inside an isolated iframe in your own browser and captured with the html2canvas library. Nothing is uploaded — the image is produced entirely on your device, which makes it fast and keeps your markup private. The trade-off is fidelity: html2canvas reimplements CSS layout in JavaScript, so a handful of advanced features (some filters, blend modes, and newer layout properties) may not render exactly as they do in a real browser.
Server-side mode sends your HTML (or a URL) to a real headless Chrome instance on our backend, which renders the page and returns a pixel-perfect screenshot. It supports every modern CSS feature and is the only option for capturing a live webpage by its URL, since a page hosted elsewhere cannot be read directly from your browser. Choose client-side for quick, private exports of self-contained HTML, and server-side when you need exact rendering of complex layouts or want to screenshot an existing page.
PNG, JPEG, or WebP — and the DPI Scale
Pick the output format based on the content. PNG is lossless and the only one of the three that supports transparency, so it is best for graphics with sharp text, logos, or transparent backgrounds. JPEG is lossy and has no transparency — a transparent background becomes white — but produces small files for photographic content; the quality slider (1–100%) lets you trade size against artifacts. WebP is a modern format that usually beats both, giving smaller files than JPEG at similar quality while still supporting transparency, though a few older tools may not open it.
The scale control (1× to 4×) multiplies the pixel dimensions of your output without changing the layout, the same idea as a Retina or "2x" export. At 2×, a 1200×800 design is rendered as a crisp 2400×1600 image — ideal for high-resolution screens and print — while 1× keeps file sizes down for web use. Width and height accept any value up to 4096 px per side.
Frequently Asked Questions
What is the difference between client-side and server-side mode?
Client-side mode renders your pasted HTML inside your own browser using html2canvas and never uploads anything, so it is fast and private. Server-side mode sends the HTML or URL to a real headless Chrome instance for pixel-perfect rendering, supports every modern CSS feature, and is required to screenshot a live webpage.
Can I take a screenshot of any website by URL?
Yes, but only in server-side mode. A page hosted on another domain cannot be read directly from your browser, so URL capture is handled by our backend, which loads the page in headless Chrome and returns the screenshot. Switching to URL input automatically selects server-side processing.
Which format should I choose: PNG, JPEG, or WebP?
Use PNG for graphics, text, logos, or anything needing a transparent background, since it is lossless and supports transparency. Use JPEG for photographic content where small file size matters, keeping in mind it has no transparency. WebP is a good all-round modern choice that is usually smaller than JPEG at the same quality and still supports transparency.
What does the scale (DPI) setting do?
Scale multiplies the output resolution without changing the layout. At 2x, a 1200x800 design is exported as a sharp 2400x1600 image, which is ideal for high-density screens and print. Use 1x for smaller web-friendly files. Each side can be up to 4096 px.
Why does my transparent background come out white?
JPEG does not support transparency, so a transparent background is flattened to white when you export as JPEG. Choose PNG or WebP with a transparent background if you need to preserve transparency.
Some CSS did not render correctly in client-side mode. What can I do?
The html2canvas library reimplements CSS in JavaScript and does not support every feature, so advanced filters, blend modes, or newer layout properties can differ. Switch to server-side mode, which uses real Chrome for accurate rendering of complex layouts.
