Typical Use Cases
Base64 image encoding is commonly used in web development to embed images directly into HTML, CSS, or JavaScript files without requiring separate image files. This is particularly useful for small images like icons, logos, or simple graphics that need to be included in a single file delivery.
Developers also use Base64 image encoding when working with APIs that need to transmit image data as text, storing images in JSON structures, embedding images in emails to ensure they display correctly across email clients, or when implementing data URIs for faster loading of small assets without additional HTTP requests.
About Base64 Image Encoding
- Data URI Format: Base64 images start with a prefix like "data:image/jpeg;base64," followed by the encoded data
- Character Set: Base64 uses a set of 64 characters (A-Z, a-z, 0-9, + and /) plus a padding character (=)
- Encoding Ratio: Base64 encoding increases file size by approximately 33% compared to the original binary
- Performance: While convenient for small images, large Base64 encoded images can increase page load time and memory usage
