Base64 Encoder/Decoder: Essential Tool for Data Encoding

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data that needs to be stored or transferred over media designed to deal with textual data, such as email attachments, JSON data, or image data in HTML/CSS.

Our free Base64 encoder/decoder tool allows you to quickly convert text to Base64 encoding or decode Base64 strings back to their original text. This is essential for web development, API integration, and data transmission.

Common Uses of Base64 Encoding

1. Data URIs

Base64 is commonly used to embed images and other binary data directly in HTML, CSS, or JavaScript using data URIs.

2. API Authentication

Many APIs use Base64 encoding for authentication tokens and credentials to ensure safe transmission.

3. Email Attachments

Email systems use Base64 encoding to attach binary files to email messages in a text-based format.
