Encoding

Base64 Encode / Decode

Convert text to Base64 or decode Base64 content directly in the browser without sending data anywhere.

How to use

  • Choose whether to encode or decode.
  • Paste text or Base64 content into the input area.
  • Read the converted result instantly in the output panel.

Select mode

Mode and input stay saved locally on this device.

Common use cases

  • Encode text for transport or quick debugging.
  • Decode Base64 payloads copied from tools or logs.
  • Verify whether a string turns back into readable UTF-8 text.

FAQ

Does this handle Unicode text?

Yes. The implementation uses TextEncoder and TextDecoder so regular UTF-8 content works correctly.

Why would decode fail?

Decode mode fails when the input is not valid Base64 or represents bytes that cannot be decoded as text.
