Citation Formatter

Citing a source correctly shouldn’t mean digging through a 300-page style manual every time you add a footnote. The Citation Formatter takes the details of a source — a website, a book, a journal article, a newspaper piece, a video, or a social media post — and turns them into a properly formatted citation in APA 7, MLA 9, or Chicago (author-date) style, both as the in-text citation you drop into a sentence and as the full reference-list entry that goes at the end of your paper. Everything runs in your browser, so the sources you’re citing and the paper you’re writing never leave your device.

Unlike most free citation generators, which format one citation at a time and expect you to copy each one out individually, this tool builds a running bibliography as you go. Add a source, and it’s inserted into an automatically alphabetized list you can keep adding to for the rest of your research session — or the rest of the semester, since the list is saved in your browser between visits. When you’re done, export the whole thing as a plain-text file, or — if you’re using reference-management software — as a BibTeX (.bib) file for LaTeX and Overleaf, or a RIS (.ris) file that imports directly into Zotero, EndNote, or Mendeley. Most free citation tools stop at “copy to clipboard”; this one meets you wherever your workflow actually lives.

How to use the Citation Formatter

1. Pick a source type. Choose website, book, journal article, newspaper/magazine, online video, or social media post. The form adjusts to ask for the details that type actually needs — a journal article asks for volume, issue, and page range; a book asks for the publisher and edition instead.
2. Add the author(s). Enter a first and last name for each author, or leave it blank if the source has no listed author — the formatter handles “no author” citations correctly rather than leaving an awkward gap. Click “+ Add author” for sources with more than one.
3. Fill in the title, date, and source-specific fields. A “Title Case” button is available next to the title field if you need to convert a plain-typed title into proper title case for MLA or Chicago.
4. Pick your citation style. Switch between APA 7, MLA 9, and Chicago at any time — because the tool stores your source’s actual details rather than a pre-formatted string, changing styles instantly reformats everything, including every entry already in your bibliography. There’s no need to re-enter a source just because your professor wants a different style than you started with.
5. Check the live preview. Both the in-text citation and the full reference update as you type, so you can see exactly what will land on the page before you commit to it.
6. Add it to your bibliography, then repeat for your next source. Copy, edit, or remove any entry from the list at any time.
7. Export when you’re finished — copy the whole bibliography, download it as a .txt file, or grab a .bib or .ris file for your reference manager.

Common situations this solves

• Writing a research paper with a dozen-plus sources and needing a clean, correctly alphabetized works-cited or reference page at the end, without manually sorting entries or second-guessing formatting rules.
• Citing a webpage with no listed author or publish date — a common stumbling block that trips up manual citation and even some paid tools.
• Switching citation styles midway through a project because a professor, journal, or publisher requires a different one than you started drafting in.
• Building a bibliography for a paper going into Overleaf or LaTeX, where a .bib file saves you from retyping every source into BibTeX syntax by hand.
• Importing your reading list into Zotero or EndNote for a longer research project, using the .ris export instead of manually adding each source to your reference manager.
• Quickly generating an in-text citation while you’re mid-sentence drafting, without breaking your writing flow to look up formatting rules for that source type.

Frequently asked questions

What citation styles does the Citation Formatter support?

APA 7th edition, MLA 9th edition, and Chicago (author-date). You can switch between all three at any point, and every source and bibliography entry reformats automatically — you don’t need to re-enter anything.

What’s the difference between the in-text citation and the full reference?

The in-text citation is the short parenthetical (or narrative) note you place directly in your sentence — for example, (Smith, 2024) in APA. The full reference is the complete entry that appears in your works-cited, reference list, or bibliography at the end of the paper. The Citation Formatter generates both from the same source details.

Can I cite a source that has no author or no publication date?

Yes. Leave the author fields blank and the citation formats correctly using the title in place of an author name. If there’s no date, APA and Chicago automatically substitute “n.d.” (no date), which is the standard convention.

Can I add multiple sources and export the whole bibliography at once?

Yes — that’s the main advantage over a one-citation-at-a-time generator. Every source you add goes into a running, automatically alphabetized bibliography that’s saved in your browser between visits. You can copy the entire thing, download it as a .txt file, or export it as .bib or .ris.

What’s a .bib or .ris file, and do I need one?

A .bib (BibTeX) file is a plain-text bibliography format used by LaTeX and Overleaf. A .ris file is a format that reference-management software like Zotero, EndNote, and Mendeley can import directly. If you’re not using any of those tools, the plain-text or copy-to-clipboard options are all you need.

Are the citations it generates guaranteed to be perfectly correct?

The Citation Formatter follows the standard rules for the most common source types in each style and gets you a very solid, submission-ready draft. Style guides do have edge cases for unusual sources (a source with an organization as author, a reprinted classic work, a source in a language other than English), so it’s worth a quick check against your style guide for anything that doesn’t fit the ordinary mold.

Is anything I type saved or sent anywhere?

No. The Citation Formatter runs entirely in your browser — the sources you cite and the bibliography you build never leave your device. Your in-progress bibliography is saved locally so it’s still there the next time you open the tool, but it’s never uploaded anywhere.

If you’re drafting the paper itself alongside your citations, the Markdown editor & viewer is a handy place to write and preview your document before pasting in the finished bibliography. And if you’re pulling dates or URLs out of a messy source page to fill in your citation fields, Extractors can save you the manual copy-paste. For a final pass on your paper’s length before submission, the Word / character counter covers word count, reading time, and common platform limits in one place.
