Image to Base64
Drop an image and instantly get its Base64 encoding — as a raw string, a data: URI, or copy-paste-ready HTML <img> and CSS background-image snippets. Handy for embedding small icons directly into markup or emails without hosting the file.

Frequently asked questions
Are my files uploaded to a server?
No. This tool runs entirely in your browser using local processing — your files never leave your device, which also makes conversion instant with no upload wait.
When should I embed images as Base64?
For small assets (icons, tiny logos under a few KB) where saving an HTTP request matters, or in contexts that can't reference external files like some email clients. Large images are better served as normal files — Base64 adds ~33% size.
