About Image to Base64

This tool converts images to Base64-encoded strings entirely in your browser. No data is uploaded to any server.

Data URI: With the prefix enabled, the output is ready to use in CSS background-image or HTML <img src="...">.
Raw Base64: Without the prefix, you get the raw encoded string.
Supports JPEG, PNG, GIF, WebP, SVG and other browser-supported image formats.
