What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format using 64 printable characters (A–Z, a–z, 0–9, +, and /). It is commonly used to transfer data over media that are designed to handle textual content, such as embedding inline images in HTML/CSS files or sending email attachments via MIME.

Frequently Asked Questions (FAQ)
Q: Is Base64 an encryption method for securing data?
No. Base64 is an encoding scheme, not an encryption algorithm. Anyone can easily decode a Base64 string back into its original raw content.
Q: Does Base64 encoding increase file size?
Yes. Base64 encoded strings typically result in approximately a 33% increase in file size compared to raw binary storage.
