How it works

Connect once, then just ask.

Your AI assistant writes the design as code. RenderPixels renders it in a real browser and hands back the files.

  • Connect once

    Add RenderPixels to Claude, ChatGPT or any assistant that supports remote MCP. You sign in to your RenderPixels account, no API keys.

  • Ask in plain words

    Describe the text, the colors and the mood. Your AI assistant writes the design and RenderPixels renders it.

  • Checked before you see it

    Each render reports clipped text and missing fonts or images, so your assistant can fix them and try again.

  • See it before you share it

    In Claude, the image appears in the chat with Download and Copy URL. In any assistant, you get a preview page with downloads and, for share images, how the link will unfurl.

  • Links that last

    Every file gets a permanent URL you can drop straight into a page, a meta tag or a message.

Same prompt, two results

ChatGPT vs RenderPixels

I gave the same prompt to ChatGPT's image generator and to an AI assistant using RenderPixels on November 9, 2026. Both results are below, with the facts about each file.

The prompt, word for word

Create an image: an Open Graph image (1200 × 630) for my blog post "How we cut our build time in half" on the Field Notes blog, by Sam Rivera, 6 min read. Warm paper background, serif headline.

  • ChatGPT's result: Field Notes, How we cut our build time in half, by Sam Rivera, 6 min read, on textured paper.

    Shown here as a compressed copy of the 1731 × 909 original.

ChatGPT spelled every word right this time. The difference is the file: it came back at the wrong size and about 17x heavier, so it needs resizing and compressing before it works as a share image.

RenderPixels gives you the exact size, ready to upload as is. The same design can also come back in every other size in one go.

Brand kits

One brand kit, five formats

Save your colors, fonts and logo once as a brand kit, then ask for it by name. Every render uses the same kit, at the exact size each platform wants. No logo yet? Make one here too and save it to the kit.

FAQ

Questions before you start

Short answers on what RenderPixels makes, what a render costs and what happens to your images.

Still have a question? Email us with the Email support link at the bottom of this page.

  • Why not use ChatGPT's image generator?

    Image models draw pixels, so the size comes out approximate. In our side-by-side, ChatGPT returned 1731 × 909 at 2.5 MB for a 1200 × 630 request. RenderPixels renders HTML and Tailwind CSS in a real browser, so the size, text and brand colors come out exactly as written, and every file gets a permanent link. For photos and illustrations, an image model is still the right tool.

  • Which AI assistants work with it?

    Claude, Claude Code, ChatGPT, GrokBot and any AI assistant that supports remote MCP with OAuth. Setup takes a minute.

  • Can it make photos or illustrations?

    It doesn't generate photos. It renders HTML and CSS, so it draws text, shapes and SVG illustrations, and it can place a photo from any https URL. For a photo-real picture, make it with an image model and bring it in by URL.

  • Can I use my own logo and photos?

    Yes. Save your logo in a brand kit, from an https URL or from an earlier render, and use any photo by its https URL. Fonts can be any Google Fonts family or your own .woff2 file.

  • Does editing an image cost another render?

    Yes. Each edit is a new render, and so is a re-render to fix clipped text or a missing font. Each counts as one of your 50 free renders this month, or one credit after those. A render that makes several sizes at once, like a full favicon set, still counts as one.

  • Can I use the images commercially?

    Yes. You own the images you make. You need the rights to what goes into them, like fonts, logos and photos. The Terms have the details.

  • What happens to my links if I delete my account?

    We delete your renders and their images, so their links stop loading. Download anything you want to keep before you delete your account. More in the Privacy policy.
