What is a Base64 image data URI?

A data URI embeds the image directly as a Base64 string in your HTML or CSS, like: img src data:image/png;base64,... No separate image file is needed.

When should I use Base64 images?

For small icons, inline email images, or when you want to reduce HTTP requests. Avoid it for large images as Base64 is about 33% larger than the binary file.

What image formats are supported?

JPG, PNG, SVG, GIF, and WebP are all supported.
