img2css

Convert any image to pure CSS.

• To use it go to https://javier.xyz/img2css
• Looking for a programmatic way to do this? See https://github.com/javierbyte/canvas-image-utils
• I also made a per-pixel animation experiment, see https://github.com/javierbyte/morphin

How does it work?

It has two different outputs, pure css shadow matrix [1] and base64 embedded image [2].

• Pure CSS: This output was created by resizing and setting each pixel as a box-shadow of a single pixel div, so no img tag or background-image is needed. This can result in huge outputs, and the use of this output is not recommended for production unless there is no other option.
• Base64: The entire image file is embedded inside the <img> tag using base64, so no need external hosting is needed.

Development

pnpm install
pnpm dev

pnpm build writes the static site to out/. Pushing to main deploys it to the gh-pages branch, which javier.xyz/img2css serves.
