FAQ
Frequently asked questions
Does this handle emojis and accents?
Yes. The encoder is Unicode-safe (UTF-8), so emojis, accented characters and non-Latin scripts encode and decode correctly without mangling.
What's a Base64 data URL good for?
A data URL embeds a small image or font directly into your HTML, CSS or JSON, saving an HTTP request. It's handy for tiny icons, email signatures and inline assets.
