Frequently Asked Questions

What is a Data URI and when should I use it?

A Data URI embeds file content directly in a URL using the data: scheme. Use it for small files (< 10KB) to reduce HTTP requests, create self-contained documents, or embed resources inline.

What's the difference between base64 and percent encoding?

Base64 is more compact for binary data and images, while percent encoding is human-readable for text. Base64 increases size by ~33%, while percent encoding varies based on special characters.

Why does my Data URI make the file larger?

Data URIs have encoding overhead. Base64 adds ~33% size, plus MIME type headers. For small files, this is acceptable to avoid HTTP requests, but large files should use separate URLs.

How does MIME type auto-detection work?

The tool analyzes content patterns: JSON structure, HTML/XML tags, CSS syntax, JavaScript keywords, and binary signatures for images. Manual override is available for accuracy.

Are there size limits for Data URIs?

Browsers typically support 2-32MB Data URIs, but performance degrades significantly above 100KB. Keep Data URIs small (< 10KB) for best practices and avoid them for large media files.
