Frequently Asked Questions

What is a Base64 Data URI?
A Data URI allows you to embed binary image data directly inline within HTML and CSS files using standard ASCII text, removing the need for an external file request.
Does Base64 encoding increase image file size?
Yes, Base64 encoding converts 3 binary bytes into 4 ASCII characters, resulting in an approximately 33% increase in data size compared to raw binary.
Can I convert large photos to Base64?
While technically possible, Base64 is best suited for icons, small badges, and email newsletter assets under 100 KB to avoid bloat in your HTML/CSS bundles.
