Paste HTML or upload a file, then capture a beautiful screenshot for social media and docs.
Screenshots are rendered in your browser. Some CSS features may render differently than in a full browser. JavaScript execution is sandboxed for security.
The pipeline is: your HTML text → an iframe sandbox renders it just like a real page → html2canvas walks the rendered DOM and redraws every element onto a 2D canvas → the canvas is exported as a PNG. The device presets only change the viewport width, so your layout reflows exactly as it would on that screen size.
The sandbox keeps untrusted scripts away from your browsing session. Some exotic CSS (like backdrop-filter) may look different in the capture than in a live browser — the disclaimer calls this out.
You want a doc screenshot that mirrors how readers see it.
To screenshot code beautifully: paste your snippet, pick syntax highlighting and a window style, set gradient and shadow, then export a crisp 2x PNG — all rendered locally so proprietary code never leaves your device.
FreeToolHub Code Screenshot Generator is a free browser-based tool that turns code or HTML into polished shareable images, no signup, no upload.
Render HTML into a beautiful screenshot, perfect for sharing code. Free, in-browser.
The Code Screenshot Generator turns source code or rendered HTML into polished, shareable images. Paste a snippet or an HTML fragment, choose a window style, and export a PNG. The tool renders real syntax highlighting, wraps the code in a macOS-style or plain window frame, and lets you control background gradient, padding, shadow depth, corner radius, and canvas width, the visual vocabulary popularized by code-sharing posts on X and dev blogs. Everything happens locally in your browser: the code you paste, which may be proprietary, never leaves your machine, and no account or watermark is involved. A Sample button loads a decorated snippet so you can see every styling option in action before pasting your own.
Developers posting on X, LinkedIn, or Reddit use it because plain code pastes lose formatting while a framed image with syntax colors earns attention and screenshots well on mobile. Technical bloggers embed styled snippets without fighting their CMS code blocks. Teams writing internal changelogs and design reviews capture before-and-after code states in one consistent visual style. Teachers and course authors produce readable code illustrations for slides. It is equally popular in security-conscious workplaces where pasting code into random online services is banned, since this renderer runs entirely client-side, making it a safe default even for unreleased feature branches.
(1) Paste your code, or toggle to HTML mode to render markup instead of highlighting it. (2) Pick a language for syntax highlighting so keywords, strings, and comments get distinct colors. (3) Style the output: choose a window chrome, set the background gradient or solid color, adjust padding, border radius, and shadow, and toggle line numbers. (4) Export as PNG at 1x or 2x scale; the 2x option keeps text crisp on retina displays and print. The preview updates live, so every slider change is visible instantly, and the exported image matches the preview pixel for pixel.
On social platforms, monospace code blocks render in whatever font and size the platform dictates, often without any syntax color, and long lines wrap into unreadable ribbons. An image fixes all three: you control the font, the palette, and the line breaks, and the framed window with a gradient background signals effort, which measurably lifts engagement on developer timelines. Practical craft rules make the difference between amateur and professional output: keep snippets under roughly 15 lines and crop to the interesting part, use 2x export so text stays sharp, pick a dark theme with a contrasting background rather than default white, and let the syntax highlighter do the emphasis instead of bolding text manually. For documentation and READMEs, real code blocks remain better for copy-paste; images are for presentation contexts.
Paste the code into this generator, pick a syntax-highlighting language, choose a window style, gradient background, and shadow, then export a 2x PNG for crisp retina display — all in your browser with no signup.
Yes. This tool renders entirely client-side — your code never leaves your device, making it safe for proprietary or unreleased code even in workplaces that ban pasting into external sites.
PNG at 2x scale. It keeps monospace text sharp on retina displays and in print, and the larger pixel dimensions prevent blurring when platforms compress uploads.
Images preserve your font, syntax colors, and line breaks, while platform code blocks strip formatting and wrap long lines. A framed snippet with a dark theme and gradient background is measurably more attention-grabbing on X and LinkedIn.
It renders your HTML and CSS using a headless browser engine, producing pixel-perfect screenshots at 1x or 2x resolution. Supported output: PNG (lossless) and JPEG (adjustable quality 1-100). Ideal for code snippet sharing, bug reports, and documentation—no need to open DevTools or install browser extensions.
Yes. Set custom viewport width (320px to 3840px), height, device pixel ratio, and background color (including transparent PNG). Add padding, rounded corners, and a macOS-style window frame for polished social media images. Export resolution up to 4K for print-quality documentation screenshots.
