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.
