About the Image to Base64 Converter

This free online tool encodes any image into a Base64 string directly in your browser — nothing is uploaded to a server, so your images stay private the entire time. Base64 encoding lets you embed images directly inside HTML, CSS or JSON without a separate image file.

  • Data URI — the full data:image/...;base64,... string, ready to paste anywhere an image URL is expected.
  • Raw Base64 — just the encoded string, without the Data URI prefix.
  • CSS background — a ready-to-use background-image declaration.
  • HTML <img> — a complete image tag with the Base64 data embedded in the src attribute.

Keep in mind Base64 encoding increases file size by roughly 33%, so it's best suited for small icons, logos and inline graphics rather than large photographs.
