Encode CSS source into Base64. Common when embedding stylesheets directly into data URIs or transmitting them through escaping-hostile channels.
Embedding small stylesheets inside data URIs, stashing critical CSS into deploy artifacts, or sharing rules in chat without escape headaches.
Working with source files? Pair this with CSS Beautifier or use HTML to Base64 for markup-specific payloads.
Is the output minified?
No. The bytes are encoded verbatim. Minify the input first if you want a smaller payload.
