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.
