Which characters does the tool strip?

It strips all nine Hungarian accented vowels — á, é, í, ó, ö, ő, ú, ü and ű — to their base letters a, e, i, o, u. This includes the double-acute ő and ű, which are unique to Hungarian and often break naive accent-removal tools.

What are ő and ű, and why are they tricky?

ő and ű are long vowels written with a double-acute accent, distinct from the dieresis ö and ü. Many tools only know about the common European accents and leave ő and ű untouched; this tool maps both to o and u explicitly.

Is letter case preserved?

Yes. An uppercase accented vowel such as Á maps to uppercase A, and a lowercase á maps to a. Only the accents are removed, so the casing of your text stays exactly as you typed it.

No. The character mapping runs entirely in your browser as bundled JavaScript. Nothing you paste is sent to a server, so the tool also works offline and keeps private text on your device.

Q: Will it change non-vowel characters?

No. Only accented vowels are mapped; every other character, including spaces, punctuation, digits, and unaccented letters, passes through unchanged. That makes the output safe for slugs and identifiers.

The Hungarian Diacritic Remover converts accented Hungarian text into plain ASCII, replacing every accented vowel with its base letter. It is built for URLs, file names, database keys, and legacy systems that cannot store Hungarian accents — and it correctly handles the double-acute vowels that trip up generic accent strippers.

How it works

The tool uses a fixed character table that maps each of the nine Hungarian accented vowels to its base letter, preserving case: á→a, é→e, í→i, ó→o, ö→o, ő→o, ú→u, ü→u, ű→u (and their uppercase forms). Every other character — spaces, punctuation, digits, and unaccented letters — passes through unchanged, and the tool reports how many diacritics it removed.

The double-acute catch

Hungarian has two long vowels written with a double-acute accent, ő and ű, which are different letters from the dieresis-marked ö and ü. Many accent-removal tools only know the common Western European accents and silently leave ő and ű in place, producing broken output. This tool maps both explicitly, so the result is fully ASCII.

Tips and notes

Case is preserved, so the output is suitable for case-sensitive identifiers.
Only vowels carry accents in Hungarian, so consonants and punctuation are never altered.
The result is safe for slugs, file names, and any system limited to the basic Latin alphabet.
