What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It uses a set of 64 characters (A-Z, a-z, 0-9, + and /) to represent binary data, with = used for padding.

Common Use Cases

• Email Attachments - Base64 is used in email systems to encode binary attachments for transmission over text-based protocols.
• Data URIs - Embedding images or other binary data directly in HTML, CSS, or JavaScript using data: URIs.
• API Communication - Safely transmitting binary data in JSON payloads or other text-based API formats.
