About the Base64 Encoder and Decoder

The Zadein Base64 tool encodes plain text or binary data into Base64 format and decodes Base64 strings back to readable text. It supports Unicode characters including emojis and non-Latin scripts, and all processing happens in the browser.

How to use

  1. 1Paste your text or Base64 string into the input field.
  2. 2Click Encode to convert text to Base64, or Decode to convert Base64 back to text.
  3. 3Copy the output from the result field.

Common use cases

  • Encode authentication credentials for use in HTTP Authorization headers.
  • Decode a Base64 payload found in a JWT or API response.
  • Encode binary data for safe transmission in a text-based protocol.
  • Inspect Base64-encoded data in configuration files or scripts.

Frequently asked questions

Is Base64 a form of encryption?

No. Base64 is an encoding scheme, not encryption. It makes data safe to transmit as text but does not protect it — anyone can decode it without a key.

Does it support Unicode and special characters?

Yes. The tool uses a Unicode-safe implementation that correctly handles emojis, accented characters, and non-Latin scripts.

Can I encode files with this tool?

This tool is designed for text encoding and decoding. File-to-Base64 conversion is not currently supported.
