Acronym Generator

Tokenise the phrase into words, drop common English stop words (the, of, and, ...), take the chosen letter from each remaining word, then optionally look the result up in a small dictionary of well-known abbreviations.

Letter position

• First letter — the standard way to form an acronym (FBI from Federal Bureau of Investigation).
• Last letter — useful when you want the trailing character of each word.
• Custom index — pick any 0-based position. Useful when you want a different syllable or character.

Stop words

A built-in list of ~80 common English words is removed before extraction. "Federal Bureau of Investigation" → FBI, not FBOI. You can disable the filter or pass your own list.

Dictionary lookup

If the resulting acronym matches a known abbreviation (HTML, CSS, JSON, ASAP, ...), the long form appears as a hint. The dictionary is small and hand-curated — it is the "did you mean?" hint, not a comprehensive reference.

Output styles

Six renderings are produced simultaneously: plain, dotted (F.B.I.), dashed (F-B-I), spaced (F B I), lower, and title. Copy any of them with the Copy button or by clicking the code box.
