Image to Base64 Encoder

Convert images to Base64 strings for embedding in HTML, CSS, or JSON

About Base64 Encoding

Base64 is a binary-to-text encoding scheme that converts binary data (like images) into ASCII text. This allows images to be embedded directly in HTML, CSS, or JSON without requiring separate HTTP requests.

When to Use Base64 Images:

  • Small icons and logos - Reduce HTTP requests
  • Email templates - Embed images directly in HTML emails
  • Single-file applications - Everything in one HTML file
  • CSS sprites alternative - Embed background images in CSS
  • JSON APIs - Include image data in API responses

Considerations:

  • Base64 increases file size by ~33%
  • Large images should use traditional file hosting
  • Not cached separately by browsers
  • Best for images under 10KB
