FAQ

What is Base64?

Base64 is an encoding scheme that converts binary or text data into ASCII characters. It's commonly used to embed binary data in text formats like JSON, HTML, or email.

When would I use Base64 encoding?

Common uses include encoding images or files to embed in HTML/CSS data URLs, passing binary data in JSON APIs, and encoding credentials in HTTP Basic Auth headers.

Is my data sent to a server?

No. Encoding and decoding happens entirely in your browser. Nothing is transmitted anywhere.
