About Base64 Encoding

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format.

Encoding: Converts text or binary data into a Base64 string using a 64-character alphabet (A-Z, a-z, 0-9, +, /).

Decoding: Converts Base64 strings back to their original text or binary format.

Common Uses: Email attachments, embedding images in HTML/CSS, API authentication, and data transmission.

File Support: You can upload files to encode them to Base64 or decode Base64 files back to their original format.
