Convert HTML to image

Sometimes the deliverable is not a document, it is a picture: an ad creative, a social visual, a UI mockup, a chart for a doc. If the source is HTML (hand-coded or generated by Claude, ChatGPT or Gemini), screenshots and JavaScript libraries will betray the design. This converter renders your HTML in a real Chromium browser and captures it as a high-resolution JPG or PNG, exactly as it looks on screen.

Your file is processed in an isolated browser and deleted immediately after conversion.

Why the usual HTML-to-image approaches fail

  • OS screenshots are capped at your monitor's resolution and catch browser chrome, cursors and scrollbars.
  • html2canvas and similar libraries re-implement rendering in JavaScript and miss modern CSS: backdrop-filter, blend modes, some gradients.
  • Browser extensions rarely capture at exact design dimensions and compress aggressively.
  • Multi-frame HTML files (ad variations, carousels, decks) need every frame captured, not just the first.

How to convert

  1. 1.Upload your .html file or a .zip with its assets.
  2. 2.Pick JPG or PNG in the Format option.
  3. 3.The engine renders the page in headless Chromium at 2x resolution: a 1920x1080 design becomes a 3840x2160 image.
  4. 4.One frame downloads as a single image; multi-slide files download as a zip of numbered images.

JPG or PNG: pick per use

Both formats are captured from the same 2x Chromium rendering, so the pixels are identical before encoding. JPG (quality 92, full chroma resolution) is several times smaller and ideal for ad platforms and social media. PNG is lossless: the right choice for UI screenshots, sharp small text, flat-color graphics and archiving. The dedicated HTML to JPG and HTML to PNG pages go deeper on each.

FAQ

What resolution are the images?

Twice the CSS dimensions of the design. A 1920x1080 creative is captured at 3840x2160. Long documents are captured across their full height at the same density.

My file contains several slides or ad variations. What do I get?

A .zip archive with one numbered image per slide (slide-01.jpg, slide-02.jpg…), captured in order. Single-frame files download as a plain image file.

Which AI tools does this work with?

Any tool that outputs HTML: Claude (Artifacts, Claude Design), ChatGPT, Gemini, Copilot, v0, Lovable, Bolt. Export the HTML, upload it here, pick JPG or PNG.

Can I still get a PDF instead?

Yes. PDF is the default format; JPG and PNG are options in the same converter.
