What is Base64 encoding?

Base64 is a method of encoding binary data as ASCII text using 64 safe characters. It's commonly used for transmitting data over text-based protocols like email and HTTP.

Why do I need to encode text to Base64?

Base64 encoding is useful when you need to transmit binary data through systems that only support text. It's commonly used in emails, URLs, and APIs.

Is my data safe when using this tool?

Yes, all data is processed entirely in your browser. Nothing is sent to any server. You can use this tool offline without any security concerns.

What's the difference between encoding and encryption?

Encoding converts data into a different format for transmission. Encryption scrambles data to keep it secret. Base64 is encoding, not encryption - the data can be decoded by anyone.

What character limit does this tool support?

This tool supports up to 10,000 characters per operation, making it suitable for most text and small file encoding tasks.

How It Works

Encoding: Converts text into a string using 64 safe characters (A-Z, a-z, 0-9, +, /)
Decoding: Converts Base64 strings back to original text
Padding: "=" characters at the end are used for alignment
Use Case: Commonly used for transmitting binary data over text-based protocols
Size: Encoded text is approximately 33% larger than original
Real-time processing: Results are updated instantly as you type
Bidirectional: Easily switch between encode and decode modes
