Frequently asked questions
What is Base64 encoding?
Base64 converts binary image data into a text string that can be embedded directly in HTML, CSS, or JSON without needing a separate image file.
When should I use Base64?
Use it for small icons and logos (under 10KB) to reduce HTTP requests. Avoid it for large images as Base64 increases file size by ~33%.
