About Base64 Encode / Decode
Encode and decode Base64 with correct UTF-8 handling, so emoji and accents survive the round trip. Everything runs locally in your browser; nothing is uploaded. Only the current result is shown — no history or side-by-side comparison.
Base64 Encode / Decode reads “Text” from the form above and writes the answer into the results panel. There is no account, no upload and no server round-trip: the JavaScript on this page does the work on your own device.
How to use Base64 Encode / Decode
- Open Base64 Encode / Decode from Text & Code, or find it with the search box in the header.
- Fill in the fields shown above: “Text”.
- Press Encode →. The result replaces whatever was shown before; only the current run is displayed, never two results side by side.
- Use Copy to put the result on your clipboard. A message appears only when something was actually copied.
A worked example
Enter your own values in the fields above and press Encode →. Change any input and press again; the result is recalculated from the current inputs and replaces the previous one.
Frequently asked questions
Is what I type uploaded anywhere?
No. Base64 Encode / Decode processes “Text” with JavaScript inside your browser. Your inputs and the result stay on your device; Utilixo keeps no copy of them.
Can I keep several results to compare?
No. Each press of Encode → rebuilds the result from the current inputs and overwrites the previous one. To compare runs, note the earlier result down yourself.
Anything specific to watch with Base64 Encode / Decode?
The result depends only on the fields shown above (“Text”); change one of them and press Encode → again to get an updated answer.
How do I take the result away?
Press Copy after a result appears. The copy button only reports success when there is content to copy.
Do I need to sign up or pay?
No. Base64 Encode / Decode is free, needs no registration and has no usage limit. Open the page and use it.
