Frequently asked questions
What is a Base64 image?
A Base64 image is the raw image data encoded as a text string, usable as a data URI (data:image/png;base64,...) in HTML and CSS.
When should I use Base64 images?
For small icons and logos embedded in CSS or email templates. Avoid for large images as Base64 is ~33% larger than the original file.
