Free Citation Generator
Paste a website URL, a DOI, or a book's ISBN and get a complete, correctly formatted citation in APA 7, MLA 9, Chicago, Harvard, and IEEE — all five at once, ready to copy. No account, no paywall, no citation limit.
Citation[Z] pulls source details from authoritative databases (CrossRef for journal articles, OpenLibrary and Google Books for books, the page's own metadata for websites), so the citation is built from the publisher's record — not guesswork.
Paste any web page address
How it works
- Pick your source type — Website URL, DOI, ISBN, or Manual Entry for anything else.
- Paste the identifier — the full web address, a DOI like
10.1152/physrev.00032.2012, or a 10/13-digit ISBN. - Click Cite — we fetch the authors, title, container, date, and publication details automatically.
- Switch styles and copy — the same source renders in all five styles; pick yours and copy with one click, italics preserved.
One source, every style
The same journal article formatted by the generator in each supported style — note how author names, dates, and italics shift between formats:

What you can cite
Websites — any public page. We read the page's metadata for author, title, site name, and publish date, and add the access date your style requires. Journal articles — paste the DOI and the citation is built from the CrossRef registry record, the most reliable source possible. Books — paste the ISBN from the copyright page or the back cover. Everything else — reports, lectures, interviews, podcasts, and any source without an identifier work through Manual Entry with type-specific fields.
Why accuracy matters (and how we keep it)
Citation generators have a bad reputation for mangling author names, dropping italics, or using outdated edition rules. Citation[Z] formats against current editions — APA 7th, MLA 9th — and handles the edge cases that trip up most tools: organizations as authors, missing dates (n.d.), 21+ author truncation in APA, et al. rules in MLA, and title-position fallback when no author exists.
Every citation is still worth a 10-second read before submission — if a website publishes wrong metadata, the citation inherits it. Each result has an Edit button so you can fix any field without starting over.
Build the whole bibliography while you're here
Every result has an Add to bibliography button. Collect your sources as you work, then open the Bibliography Builder to get an alphabetized, correctly titled reference list — References, Works Cited, or Bibliography depending on style — and export it as a Word document with hanging indents and double spacing already applied.
The mistakes a generator prevents
Hand-formatted citations fail in predictable places, and graders know exactly where to look:
- Inverted-name errors — forgetting to invert (APA/Harvard), or inverting every author when the style inverts only the first (MLA, Chicago).
- Italics in the wrong place — italicizing the article title instead of the journal, or losing italics entirely when pasting between apps. Our copy button preserves them.
- Casing mismatches — Title Case in an APA title (APA wants sentence case) or sentence case in MLA (wants Title Case).
- Outdated edition rules — publisher cities (gone since APA 7), "Retrieved from" before every URL (gone), listing only 7 authors (now 20).
- Punctuation drift — the comma-vs-period-vs-colon sequence differs per style and is exactly the kind of detail humans normalize incorrectly across 20 entries.
How citation styles differ — 60-second version
APA 7 (psychology, education, social sciences): author–date. Initials for first names, the year right after the authors, sentence-case titles. MLA 9 (English, humanities): author–page. Full first names, Title Case, the date near the end, list titled Works Cited. Chicago (history, publishing): reads like prose, pairs with footnotes. Harvard (UK/international universities): APA's sibling with single-quoted titles and Available at: for URLs. IEEE (engineering, CS): numbered [1] references in citation order, initials before surnames.
Not sure which you need? Your syllabus decides — and if it truly doesn't, see How to Choose a Citation Style. Since every result here renders all five, picking late costs nothing.

Go Premium — $5/monthFrequently asked questions
- Is the citation generator really free?
- Yes — generating, converting, and exporting citations is free with no usage limit, supported by ads. A free account adds saved citations and projects. Premium ($5/month) adds research features like finding sources by topic.
- Which citation styles are supported?
- APA 7th edition, MLA 9th edition, Chicago, Harvard, and IEEE. Every generated citation can be switched between all five instantly.
- How is this different from Citation Machine or EasyBib?
- Same job, cleaner experience: no citation limits, no locked styles behind a subscription, exports included free, and ads that never interrupt the generator itself.
- Can I cite something without a URL, DOI, or ISBN?
- Yes — Manual Entry handles any source. Choose website, book, or journal article and fill in the fields; the formatting rules are applied exactly as they are for automatic lookups.
- Where does the citation data come from?
- CrossRef's registry for DOIs (the publisher's own filed metadata), OpenLibrary and Google Books for ISBNs, and the page's structured metadata for URLs — the same sources libraries rely on. Nothing is guessed by an AI.
- Can I save citations for later?
- Yes — create a free account and every citation you save is kept in your history, organizable into projects with tags and notes. Without an account, your bibliography lives in your browser until you clear it.
- Does it handle in-text citations too?
- The reference entry contains everything the in-text form needs, and every style page here shows the exact in-text patterns — see APA In-Text Citations and MLA In-Text Citations for complete rules.
