Frequently Asked Questions
When should I use Base64 images?
Base64 is useful for small icons and critical above-the-fold images to eliminate HTTP requests. Avoid it for large images — Base64 encoding increases file size by ~33%.
Can I use the output in CSS?
Yes. Paste the output directly as a CSS background-image: url('data:image/...') value.
