The Base64 Encoder/Decoder is a practical online conversion tool that can quickly convert text and images to Base64 encoding, or convert Base64 encoding back to original data. It's suitable for web development, API debugging, data transmission, and various other scenarios, especially for developers who need to handle data encoding. It supports batch text processing with fast conversion speed, making it a valuable assistant for your online Base64 conversion needs.

What is Base64?

Base64 is an encoding scheme that represents binary data using 64 printable ASCII characters. It converts binary data into a string of ASCII characters, allowing data to be transmitted in environments that only support text, such as email or certain HTTP requests. Base64 encoding is commonly used for transferring images, audio, and other binary files over the internet.

When to Use Base64 Converter?

• Embedding small images in HTML or CSS to reduce HTTP requests
• Transferring binary data through systems that don't support binary transmission
• Encoding API authentication information (like username and password)
• Handling data containing special characters to ensure it's not lost or tampered with during transmission

Features

• Support for bidirectional conversion between text and Base64 encoding
• Correct encoding and decoding of Unicode characters
• One-click copy of conversion results for convenience
• Clear Base64 encoding reference table to help understand encoding principles
