Base64 is an encoding method that represents binary data using 64 printable characters. These characters include uppercase and lowercase letters, numbers, and two special characters, commonly used for transmitting binary data in text-based systems.
Image to Base64: Reads the binary data of an image file and converts it into a string according to Base64 encoding rules. Base64 to Image: Decodes the Base64 string back to binary data, which is then parsed and displayed as an image by the browser.
Base64 encoded images are commonly used for: 1. Embedding small images in web pages to reduce HTTP requests; 2. Transmitting images through APIs that don't support direct file uploads; 3. Storing or transmitting images as text in specific scenarios.
