Frequently Asked Questions
What is a data URL and how does it work?
A data URL is a URI scheme that allows you to embed small files directly into web pages as base64-encoded strings. The format is 'data:mime/type;base64,encoded-content' which eliminates the need for separate HTTP requests to load small assets like images, fonts, or documents.
What file types can I convert to data URLs?
Our tool supports over 30 common file types including images (PNG, JPG, GIF, SVG), fonts (WOFF, TTF), documents (PDF, TXT), and web assets (CSS, JS, JSON). The tool automatically detects MIME types and provides appropriate encoding for each file format.
Are there size limits for data URLs?
While there's no strict technical limit, browsers may have practical limitations. Internet Explorer has a 32KB limit, while modern browsers can handle much larger data URLs. Our tool provides size analysis and browser compatibility warnings to help you optimize for your target audience.
Can I decode existing data URLs back to files?
Yes, our tool includes data URL parsing functionality that can extract the original file content from data URLs. This is useful for analyzing existing data URLs or converting them back to downloadable files for editing or inspection.
