What is Image to Base64 Encoding?
Base64 is a method for encoding binary data, like an image, into a text-based format. This tool converts your entire image into a long string of ASCII characters. The resulting string is a "Data URI" that can be used directly in code.
Why Convert an Image to Base64?
- Embedding in HTML/CSS: The primary use is to embed images directly into HTML (`
`) or CSS (`background-image: url(data:image/png;base64,...)`). This eliminates the need for a separate HTTP request to fetch the image, which can sometimes improve loading performance for small, critical images like icons. - Data Transmission: It allows image data to be transmitted as part of a text-based format like JSON or XML without causing parsing issues.
Note: Base64-encoded images are typically about 33% larger in size than the original binary file. This method is best suited for small images. For large images, linking to the file directly is usually more efficient.
