File to Data URI Converter

Convert any file — fonts, SVGs, images, WASM, small binaries — into a base64 data URI you can embed directly in HTML, CSS, or JavaScript. Get ready-to-paste snippets for <img>, CSS url(), and @font-face src. Also encode raw text with a chosen MIME type. Everything runs locally in your browser.

Why choose File to Data URI Converter?

The File to Data URI Converter provides an efficient way to transform files such as images, fonts, and SVGs into base64 data URIs directly within your browser. It generates ready-to-paste snippets for HTML, CSS, and JavaScript, eliminating the need to manage external asset files. Because processing runs locally on your device, it offers a secure and fast workflow for embedding small assets.

Good to know: Very large files will significantly increase the size of your code and may impact page load performance when embedded directly.
