Notes

  • A Data URL usually looks like data:image/png;base64,xxxx and can be used in img src or CSS url.
  • Plain Base64 has no MIME type; this tool restores it as image/png by default. Keep the full Data URL when the type matters.
  • Base64 is usually about 33% larger than the original binary, so large images should not be inlined into HTML or CSS.
  • All conversion is done locally in the browser; images are not uploaded to the server.
