Base64 Encoder/Decoder

Convert text and binary data to Base64 format for secure transmission and storage. Perfect for email attachments, API payloads, and web applications.

About Base64 Encoding

Base64 encoding is a crucial method for converting binary data into ASCII text format, making it safe for transmission across systems that only support text data. It's widely used in email attachments, API communications, and web applications.

Frequently Asked Questions

What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data using a set of 64 characters, making it safe for transmission through text-based systems.

Why use Base64 encoding?

Base64 encoding is essential when you need to transmit binary data through systems that only handle text, such as email attachments or API calls.

Is Base64 encoding secure?

Base64 is an encoding method, not encryption. While it obscures data, it should not be used for security. Our tool processes all data locally in your browser for privacy.

What data can be encoded?

Any type of data can be Base64 encoded, including text, images, documents, and binary files. Our tool specializes in text and small binary data encoding.
