Base64 Encode / Decode — free online

Sometimes you get a block of text that looks like gibberish — letters and numbers with an equals sign at the end — and you just need to know what it really says. Or you have to turn some text into that format because a script or a config file wants it that way. We added a free tool that does both — Base64 Encode / Decode — right in your browser.

What it does

It converts text to Base64 and back the other way. It handles normal UTF-8 text, so accents and other languages work fine, and it also does the URL-safe variant for when the result has to fit into a web address. You paste one side, you get the other.

Nothing leaves your device

The whole thing runs in your browser. Your text is never uploaded to a server and nothing is saved anywhere. When you close the tab, it's gone. So even if the text is something private, it stays with you.

How to use it

  1. Open Base64 Encode / Decode and pick encode or decode.
  2. Paste your text into the box.
  3. Copy the result.

It's free with no limit. There are more small tools on the Apps page.
