About Image to Base64

Encode an image as a Base64 data URI so you can embed it directly in HTML, CSS, or Markdown without a separate file request. Handy for small icons and inline assets. Encoding happens entirely in your browser.

When to use it

Base64 data URIs are best for small images — they're ~33% larger than the binary file, so large images are better served as normal files.
