Base64 Encoder & Decoder

A simple, fast, and secure online tool to encode text to Base64 and decode Base64 to text, all in your browser.

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It's commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text. This ensures that the data remains intact without modification during transport.

Common Base64 Uses

  • Encoding binary data in emails (MIME)
  • Storing complex data in XML or JSON
  • Embedding image data directly in HTML/CSS
  • URL encoding for complex parameters
  • Storing binary data in databases that don't support binary types

Privacy First

All encoding and decoding happens entirely in your browser. Your data never leaves your device.

No Size Limits

Process text of any length without artificial limitations.

Fast & Efficient

Optimized algorithms ensure quick processing even for large inputs.
