Image Generation

Iteration Layer vs HTML/CSS to Image

HTML/CSS to Image renders HTML in a browser — output depends on how Chrome interprets your CSS, not what you specified.

Why developers switch from HTML/CSS to Image

Browser-based rendering means subtle differences between runs — not pixel-perfect consistency.

Layer-based composition vs. browser rendering

HTML/CSS to Image renders HTML through a headless browser — output can vary with CSS interpretation, font loading, and rendering quirks. Our layer model is explicit: each element is positioned, sized, and styled with precision.

AI operations on every layer

HTML/CSS to Image has no AI operations. We apply background removal and smart crop with object detection to individual layers as part of the same generation request.

Bundled fonts, no external hosting

HTML/CSS to Image requires fonts to be accessible via URL — you host them or reference a CDN. Our API bundles all fonts used in generation; no external font hosting needed.
