Base64 Encoder / Decoder

Encode text to Base64 or decode Base64 strings directly in your browser.

What is Base64?

Base64 is an encoding method used to represent binary data as a sequence of text characters. It is commonly used when data needs to be transmitted or stored in systems that work primarily with text.

Base64 uses a set of 64 characters, including letters, numbers, and a few special characters. The encoded result is usually longer than the original data.

Common uses of Base64

  • Encoding data for APIs and web applications
  • Representing binary data inside JSON or XML
  • Embedding images and other files in web content
  • Working with authentication and tokens
  • Transferring data between systems

How to use the Base64 Encoder

  1. Select Encode.
  2. Enter the text you want to convert.
  3. Click Encode to Base64.
  4. The encoded result will appear in the Result field.
  5. Click Copy Result if you want to copy it.

How to use the Base64 Decoder

  1. Select Decode.
  2. Paste your Base64 string into the input field.
  3. Click Decode Base64.
  4. The decoded text will appear in the Result field.

Is Base64 encryption?

No. Base64 is encoding, not encryption. Base64 does not protect information with a secret key and should not be used as a security mechanism for sensitive data.

Anyone who has a Base64-encoded value can decode it back to its original representation.

Privacy

This tool processes your text directly in your browser. The encoding and decoding operations are performed locally using JavaScript.

No server-side processing is required for normal text encoding and decoding.
