About Base64 Encode/Decode

What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text. It is widely used to transmit data in text-only contexts, such as emails (MIME), URLs, and storage in JSON/XML.

When to use?

Use Base64 to encode inline images in CSS/HTML, transmit binary data via REST APIs, encode authentication tokens (Basic Auth), or store binary data in text fields.

UTF-8 Support

Our tool supports full UTF-8 characters, including accents, emojis, and special characters, using TextEncoder/TextDecoder for precise conversion.
