Naskh cleans up and converts Arabic text — switch between Arabic-Indic and Western numerals (٠١٢٣ ⇄ 0123), strip the tashkeel (diacritical marks), remove tatweel (kashida), and normalise the alef, yaa and taa-marbuta variants. Pick the operations you want and the result updates as you type. Nothing is uploaded.

Tashkeel covers the standard Arabic diacritics (fatha, kasma, damma, shadda, sukun and the tanwin marks) plus the superscript alef. Normalising letters is useful for search and matching but changes the spelling, so keep it off for text you want to preserve exactly. Everything runs on your device.
