Data URI Scheme Generator

Convert files and text into RFC 2397 Data URIs directly in your browser. Upload any file or paste text content to generate a complete data URI with the correct MIME type, ready to embed in HTML, CSS, or JavaScript.

使い方

File mode: Upload or drag-and-drop any file (images, fonts, CSS, JS, SVG, etc.) to automatically generate a base64-encoded data URI with the correct MIME type.

Text mode: Paste text content (HTML, CSS, SVG, plain text) and select the appropriate MIME type to generate a data URI from text input.
