Frequently Asked Questions

What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data using 64 ASCII characters (A-Z, a-z, 0-9, +, /). It's used to safely transmit binary data in text-based formats.

When should I use Base64?

Common uses include embedding images in HTML/CSS (data URIs), encoding email attachments (MIME), transmitting binary data in JSON APIs, and basic authentication headers.

What is URL-safe Base64?

URL-safe Base64 replaces + with -, / with _, and removes = padding, making the encoded string safe for use in URLs and filenames.
