Frequently asked questions

How is text encoded?

Text is encoded as UTF-8 bytes; each byte is shown as an 8-digit binary string separated by spaces.

What binary formats decode correctly?

Decode accepts groups of 0/1 bits separated by spaces or commas. Each group must represent one byte (0–255).

Is my data uploaded?

No. Encoding and decoding happen locally.
