What is Base64? Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for encoding data in URLs, email attachments, and storing binary data in text-based formats.

Common Uses: Email attachments, data URLs in web pages, storing binary data in JSON/XML, encoding credentials in HTTP Basic Authentication, and more.

Character Set: Base64 uses 64 characters: A-Z, a-z, 0-9, plus (+), and forward slash (/). The equals sign (=) is used for padding.

File Support: You can upload text files to encode/decode. For encoding, the file content will be converted to Base64. For decoding, Base64 content will be converted back to readable text.
