Frequently Asked Questions

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data using 64 ASCII characters. It's commonly used to encode data in URLs, email, and JSON where binary data isn't allowed.

When should I use Base64?

Use Base64 when you need to embed binary data (like images) in text formats, transmit data through systems that only support text, or encode data in URLs and APIs safely.

What is URL-safe Base64?

URL-safe Base64 replaces + with - and / with _ to avoid issues when the encoded string is used in URLs. Standard Base64 characters can conflict with URL special characters.
