Why decode Base64 to text?

Base64 shows up everywhere, from JWT payloads to data URIs and config files, but it is not human readable on its own. Paste a Base64 string above and instantly recover the plain text it represents.

How it works

The decoder converts Base64 back to UTF-8 plain text directly in your browser. If the input is not valid Base64, it surfaces a clear error rather than emitting nonsense. As the inverse of the Text to Base64 encoder, it completes the round trip, and since everything is processed locally, nothing is uploaded and your data stays on your device.

Frequently asked questions

Is my Base64 string sent to a server?
No. Decoding runs entirely in your browser, so the value you paste stays on your device. That keeps the tool safe for confidential data.
What happens if my Base64 is invalid?
The decoder shows a clear error message instead of producing garbled output, so you know right away when the input is malformed.
How does it relate to the Text to Base64 tool?
It is the exact inverse. Anything you encode with Text to Base64 decodes back to the original UTF-8 text here.
