About Base64 Image Encoding
Base64 image encoding converts binary image data into a text string that can be embedded directly in HTML, CSS, JavaScript, JSON, or email templates. This eliminates the need for a separate HTTP request to load the image, which can improve performance for small assets like icons and logos.
The trade-off is that Base64 encoding increases the data size by approximately 33%. For large images, it's generally better to serve them as separate files. Base64 encoding is most effective for images under 10 KB.
