Keep it small — data URIs live inside your code, so every byte is paid for twice.
- 2Copy the flavour you need
Raw Base64, an HTML img tag, a CSS background, or Markdown.
- 3Paste into your project
No files to keep. That's the point and the trade.
Questions people actually ask
When is Base64 a good idea?
Tiny icons and UI bullets that save a request. Not photos — the same bytes inflated by a third, in a file you can't cache separately.
Is anything sent anywhere?
No. The conversion is base arithmetic the browser does locally.
