Remove Accents and Diacritics from Text Online

Because those are not letters wearing a mark on top — they are distinct letters of their alphabets. Unicode decomposition can only peel away combining marks: acute, grave, umlaut, tilde, cedilla, ring. Polish ł, Croatian đ and Danish ø are single code points with nothing to decompose. Replace them with a manual find-and-replace if your target system needs them gone.

This tool performs a neutral strip: ü becomes u, ä becomes a, ö becomes o. German orthographic transliteration is a different rule set that wants ue, ae, oe, and expands ß into ss. Because that mapping depends on knowing the source language, it is not applied automatically — run three find-and-replace passes on the output if you need it.

Nothing is capped in the code; the ceiling is your tab's memory. Documents of several tens of thousands of characters convert instantly, since the work is a single pass over the string. Pastes in the megabyte range can freeze the tab for a moment, so split those into chunks.

Yes. Only accented letters change; everything else is copied character for character — newlines, tabs, double spaces, quotes, emoji. That makes it safe to push a whole CSV column or an exported list through the tool without shifting your delimiters.

Nowhere. The page issues no network request carrying your data: the script sits inside the tool file, fires on the button press and writes into the neighbouring field. No input history is kept either — reload and the fields are empty. Personal data from application forms can be cleaned here without handing it to a third-party service.

Yes. The page opens in any mobile browser and both fields are ordinary multi-line text areas, so pasting and copying behave normally. Note that the interface labels are in Russian. The copy button uses the system clipboard, and some mobile browsers ask for permission the first time you press it.
