Frequently asked questions
What is Base64 used for?
Base64 encodes binary data as ASCII text. It's commonly used to embed images in CSS/HTML, transmit binary data over email, and encode data in URLs.
Does it support Unicode?
Yes. We encode UTF-8 properly so emoji and non-Latin scripts round-trip correctly.
