What is a Base64 Data URI and why use it?

A Data URI allows you to embed image data directly into HTML, CSS, or JSON documents as text strings, eliminating extra HTTP roundtrips and optimizing initial rendering speed for icons and logos.

Which image formats are supported?

All modern image formats are supported: PNG, JPG/JPEG, SVG vector, WebP, GIF, ICO, and AVIF.

Are my images uploaded to any server?

No! All encoding and decoding operations run 100% client-side inside your browser. No files or strings are transmitted.
