Frequently asked questions
- Are my files uploaded to a server?
- No. This tool runs entirely in your browser using JavaScript — your files never leave your device.
- How does text become binary?
- Each character is encoded to UTF-8 bytes, and each byte is shown as 8 binary digits. 'A' is 01000001; multi-byte characters like emoji become several groups.
- Can I convert binary back to text?
- Yes — paste space-separated binary (or hex) bytes and click the matching decode button. Invalid bytes are reported with an error.
