Instructions
What is Base64?
Base64 encodes binary data as ASCII strings. After an image is converted to Base64, it can be embedded directly in HTML, CSS, JSON or code without an extra image-file request.
Common uses:
• In HTML: <img src="data:image/png;base64,...">
• In CSS: background: url(data:image/png;base64,...)
• Inline images in mini-programs / apps
• Images transmitted via JSON data
Note:Base64 encoding increases size by about 33%. It is recommended only for small icons (under 10KB); Base64 is not advised for large images.
