Frequently Asked Questions

You can convert PNG, JPEG, GIF, WebP, SVG, BMP, and ICO images to Base64. All common image formats are supported.

Convert images to Base64 encoded strings for embedding directly in HTML, CSS, or JavaScript. Eliminate additional HTTP requests by including small images inline in your code.

Did You Know?

Data URLs (which use Base64 encoding) were first proposed in 1998 and standardized in RFC 2397. While they save HTTP requests, browsers can't cache data URLs like regular images, so they're downloaded fresh on every page load!

  • Only use for small images (<10KB) - larger files bloat your code
  • Data URLs work in img src, CSS background-image, and more
  • Base64 adds ~33% to file size, so calculate the trade-off carefully
