FAQ

Is this a watermark remover?

No. This tool only cleans formatting artefacts you can see or select (Markdown leftovers, quotes, invisible characters, whitespace, dashes). It does not claim to detect or remove watermarks.

Is my text uploaded?

No. All rules run in your browser. Nothing is sent to our servers.

Will cleaning change the meaning?

Most rules only touch punctuation and markup. Aggressive Markdown stripping can remove emphasis markers; review the result before you publish.

Markdown cleaner vs this page?

Markdown to text focuses on converting Markdown documents to plain text. This page is a multi-rule cleaner aimed at typical AI-chat paste artefacts; Markdown stripping is one optional rule.
