Why convert images to Base64?
Base64 encoding embeds images directly into HTML or CSS, eliminating HTTP requests. Perfect for small icons, logos, email signatures, and single-file web pages. However, Base64 increases file size by ~33%, so it's best for images under 5KB.
What is Base64 encoding?
Base64 converts binary image data into ASCII text using 64 characters (A-Z, a-z, 0-9, +, /). This lets you embed images directly in HTML, CSS, or JSON without separate file requests. The trade-off: Base64-encoded images are ~33% larger than the original binary file because 3 bytes become 4 characters.
