Does it support both uppercase and lowercase hex output?

You can typically choose the case format, since both are valid representations of the same hex value.

Does it handle Unicode text, not just ASCII?

Yes, Unicode text converts correctly, encoding the actual underlying bytes of each character.

What's the difference between this and the Hex ↔ Text Converter?

They cover very similar functionality — this one is framed specifically around byte-level encoding, useful when you're thinking about the data as raw bytes rather than just "hex text."

Does Hex Encoder/Decoder upload my files to a server?

No. Hex Encoder/Decoder runs entirely in your browser using on-device processing, your files never leave your device.
