Data URI Scheme Generator

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.

How to Use

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.

Features

• File & Text Input – Upload binary files or paste text content to generate data URIs from either source
• Auto MIME Detection – Automatically detects the correct MIME type from file extensions
• Manual MIME Override – Override the auto-detected MIME type when needed
• Size Comparison – See original size vs encoded size with percentage increase
• Image Preview – Renders a live preview for image data URIs
• CSS & HTML Snippets – Ready-to-use code snippets for embedding in CSS backgrounds and HTML img tags
• Size Warnings – Alerts when the generated URI exceeds 100KB for practical usage considerations
• Client-Side Only – All encoding happens in your browser with no data uploaded to any server
