Acronym Generator
Phrase to acronym: initialism with function words skipped or kept, periods (U.S.A.), syllabic acronyms (Benelux), or an acronym expanded one letter per line.
The acronym for each phrase, the letters (or syllables) it was built from, the function words left out, the word count, and the letter-per-line form for a backronym.
Example: North Atlantic Treaty Organization → NATO; Chief of Staff → CS with "of" skipped, COS with it kept; Self-Contained Underwater Breathing Apparatus → SCUBA; Belgium Netherlands Luxembourg → Belnetlux.

How the initialism is formed, when function words are dropped, and what the syllabic and expand modes do.
Initialism
The phrase is split on spaces (and on hyphens and slashes when that option is on); the first letter of each word is taken, in capitals unless you keep the case, with a period after each if you want U.S.A. style. Leading and trailing punctuation on a word is ignored. Several phrases, one per line, are handled together and listed with their acronyms.
Function words
Most acronyms drop articles, prepositions and conjunctions: Frequently Asked Questions → FAQ but Bachelor of Arts → BA. The page holds a list of 35 such words in English, French, Spanish and Indonesian (of, the, and, for, de, la, dan, di …) and skips them except as the first word or when every word would go; the skipped words are listed so you can switch the option off — "as soon as possible" is usually ASAP, keeping them.
Syllabic and expand
Syllabic acronyms (Interpol, Benelux, sitcom) take the first syllable of each word, found as the leading consonants plus the first vowel group and the consonants after it; adjust the result by hand where the split reads oddly. Expand writes an existing acronym one letter per line with a blank after each, for inventing a backronym. Nothing leaves the browser; the same four anonymous usage counts as the rest of the site apply.
