Frequently asked questions

What are zero-width characters?

Invisible Unicode characters (like U+200B) that sneak in from copy-paste and can break rendering or search; the cleaner removes them.

Does it merge paragraphs?

No. It keeps single blank lines between blocks and only collapses three or more in a row.

Is anything sent to a server?

No — it all runs locally.
