Frequently Asked Questions

When should I inline images?

Small assets under ~10 KB (icons, logos) where one fewer HTTP request beats bytes. Large photos bloat CSS — link those normally.

Size overhead?

+33% over binary — a 30 KB icon becomes ~40 KB of text. Worth it below 10 KB, wasteful above 100 KB.

CSS usage?

Paste the data URI into url() directly. Quotes required around URIs containing special characters.

Do images upload?

No — encoding runs locally in your browser. Images never leave your device.
