How to use

2. Set only the options your task actually needs — the defaults are correct for most inputs.
3. Read the result in the right pane; it updates as you type.
4. Use Copy to take the result, or Download to save it as a file.

Examples

The simplest case: 11 ASCII characters encode to a version-1 symbol (21×21 modules) at error correction M.
