Frequently asked questions

Does Base64 encrypt data?
No. Base64 is just an encoding, reversible by anyone; it does not protect the content. For confidentiality you need real encryption.
Is my data sent to a server?
No, encoding and decoding happen in your browser.
What is Base64 used for?
To carry binary data over text channels: email attachments, embedded images (data:), tokens, credentials in HTTP headers, and so on.
