What does Base64Url Encode do?

Encodes text to URL-safe Base64 (no padding). Paste your text on the left and NMSnabbit instantly shows the base64url on the right. For example, “Hi>” gives “SGk-”. Everything runs locally in your browser — nothing is uploaded, so it stays private and works offline. You can process several values at once and copy the result with one click.

How to use the Base64Url Encode

  1. 1 Type or paste your text into the input box.
  2. 2 The base64url appears instantly in the output box as you type.
  3. 3 Tip: try the example “Hi>” to see “SGk-”.
  4. 4 Click “Copy output” to copy the result.

What you can use it for

  • Quickly encodes text to url-safe base64 (no padding) without installing anything.
  • Checking results while learning or teaching how text and base64url relate.
  • Preparing or debugging data for programming, electronics or homework.
  • Working privately when the data shouldn't be uploaded to a server.
