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
- Open Base64 Encode / Decode and pick encode or decode.
- Paste your text into the box.
- Copy the result.
It's free with no limit. There are more small tools on the Apps page.
