Is it safe to use the Binary ↔ Text online?

Yes — and ours is safer than most. Many free online tools quietly upload your files to their servers to do the work. We don't. Everything happens inside your browser on your own device, so your files never reach the internet. There's no upload step, no server copy, and no way for us (or anyone else) to see what you're working on.

Are my files uploaded to a server?

No. There's no server-side processing here. The whole tool is a tiny app that runs in your browser — we don't even have a server that could receive your files. You can confirm this by opening your browser's network tab while you use the tool: nothing leaves your device.

Do I need to sign up or pay?

No. There's no account, no email collection, no credit card. The tool is free to use as much as you want, on as many files as you want. We're supported by a few unobtrusive ads on the page — not by your data.

What if my input has commas instead of spaces?

Decode treats any non-binary character as a separator. "01001000,01101001" decodes the same as "01001000 01101001".

Why does my emoji not decode correctly?

Make sure all bytes are present — emoji are 4 bytes in UTF-8 and need all four octets in order.
