Free Citation Generator: Perfect APA, MLA & Chicago Citations

By ZeroFee Tools · October 3, 2026 · 5 min read

Formatting citations by hand is the most tedious part of academic writing, and the easiest place to lose marks. The free Citation Generator from ZeroFee Tools builds perfectly formatted references in seconds: pick a style, pick a source type, then autofill from a DOI or ISBN or enter details manually. It covers the three styles students actually use, APA 7th, MLA 9th, and Chicago, across the source types papers demand.

How do I generate an APA citation for free?

Choose APA 7th style, select your source type (book, journal article, or website), and either paste the DOI or ISBN for instant autofill or type the author, title, and date yourself. The generator formats the reference with correct punctuation, italics, and ordering, ready to paste into your reference list.

Autofill pulls real metadata, but always verify edition numbers and author spellings.

Can I trust an online citation generator for my paper?

A good generator handles the mechanical rules reliably: author order, date placement, italics, and punctuation for APA, MLA, or Chicago. It cannot judge unusual sources, so double-check anything odd like translated works, corporate authors, or missing dates against the official style guide before your final submission.

Keep a copy of your university's quick style sheet handy for edge cases.

It supports the three styles students actually use - APA 7th, MLA 9th, and Chicago - across five source types: books, journals, websites, newspapers, and theses. No account, no paywall after three citations, no nonsense. Whether you're writing a first-year essay or a thesis, correctly formatted references take seconds instead of eating your evening.

How to use the Citation Generator in 4 steps

1. Choose your citation style. Select APA 7th, MLA 9th, or Chicago from the style picker. The field labels and output format adjust to each style's rules automatically.
2. Pick the source type. Choose Book, Journal, Website, Newspaper, or Thesis. Each type shows only the fields that style requires - no guessing whether a newspaper needs a volume number.
3. Autofill or enter manually. Paste a DOI and hit “Fetch via DOI,” or a book's ISBN with “Fetch via ISBN,” to pull the metadata automatically. Or fill in Source details by hand: Authors, Year, Title, Container, Publisher, DOI, URL, and more.
4. Copy the formatted citation. Your reference appears correctly punctuated and styled - copy it straight into your bibliography or reference list.

4 practical tips

• Always verify autofill data. DOI and ISBN databases occasionally carry typos in titles or author names. A 20-second check against the source beats a wrong citation in your final paper.
• Prefer DOIs over URLs. DOIs are permanent; URLs rot. When both exist, cite the DOI - most styles (and professors) prefer it.
• Learn the “et al.” rule for your style. APA uses et al. for 3+ authors in-text; MLA for 3+; Chicago has its own thresholds. The generator handles the reference list, but your in-text citations need the same care.
• Build citations as you research. Generate each citation the moment you decide a source is useful. Reconstructing a bibliography the night before a deadline is how errors happen.
