Base64 Encoder/Decoder

Encode text or files to Base64, and decode Base64 back to text or a downloadable file. Everything runs in your browser.

How it works

  1. Use Text to encode or decode pasted content.
  2. Use File to turn one local file into Base64 or a data URL.
  3. Decoded bytes can be downloaded as a file with your chosen name and MIME type.
