About Base64 Encoding

What is Base64? Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation.
Character Set: Uses 64 characters: A-Z, a-z, 0-9, +, / (with = for padding).
Size Increase: Base64 encoding increases the size of data by approximately 33% due to the encoding overhead.
Common Use Cases: Email attachments, embedding images in HTML/CSS, data URLs, API authentication tokens, and storing binary data in text-based formats.
