How to Cite a PDF for Free: APA, MLA, and Chicago Examples

· 6 min read

Quick summary: A PDF isn’t its own citation format — you cite it the same way you’d cite the type of document it contains (report, ebook, webpage, government document), and simply note that you accessed it as a PDF. In APA and MLA, include the author, title, publication year, publisher or website, and a URL or DOI if the PDF is available online. If there’s no listed author, start the citation with the title instead.

Citing a PDF trips people up because “PDF” feels like it should be its own source type — it isn’t. A PDF is a file format, not a publication type, so the citation style depends on what the PDF actually is: a journal article, a government report, an ebook, a company whitepaper. This guide covers the most common cases in APA, MLA, and Chicago. You can also upload the PDF to our free AI PDF reader to quickly pull out the author, title, and publication date if they’re buried in the document.

What information do you need before citing a PDF?

Gather these details first — they’re required by every major citation style:

  • Author (person or organization) — check the title page, the PDF’s metadata (File → Properties), or the first/last page.
  • Title of the document.
  • Publication year (or “n.d.” for “no date” if none is listed).
  • Publisher or organization that released it.
  • URL or DOI if you downloaded the PDF from a website.
  • Page numbers for any direct quote or specific data point you’re citing in-text.

If the PDF is a scanned document with no visible metadata, see how to OCR a PDF for free to make the text (and the copyright/title page) searchable so you can find these details faster.

How to cite a PDF in APA style (7th edition)

General format:

Author, A. A. (Year). Title of document [PDF]. Publisher. URL

Example — a report with a named author:

Chen, M. (2024). Remote work productivity trends [PDF]. Bright Horizons Research. https://example.com/reports/remote-work-2024.pdf

Example — an organization as author, no individual named:

World Health Organization. (2023). Global mental health report [PDF]. https://who.int/publications/mental-health-2023.pdf

In-text citation: (Chen, 2024, p. 12) for a direct quote with a page number, or (Chen, 2024) for a general reference.

How to cite a PDF in MLA style (9th edition)

General format:

Author Last Name, First Name. "Title of Document." Publisher, Year, URL. PDF.

Example:

Chen, Maria. "Remote Work Productivity Trends." Bright Horizons Research, 2024, example.com/reports/remote-work-2024.pdf. PDF.

In-text citation: (Chen 12) — MLA uses the author’s last name and page number, no year, no comma.

How to cite a PDF in Chicago style

Notes-Bibliography format (footnote):

1. Maria Chen, "Remote Work Productivity Trends" (Bright Horizons Research, 2024), 12, https://example.com/reports/remote-work-2024.pdf.

Bibliography entry:

Chen, Maria. "Remote Work Productivity Trends." Bright Horizons Research, 2024. https://example.com/reports/remote-work-2024.pdf.

Author-Date format (in-text): (Chen 2024, 12)

How to cite a PDF with no author

Start the citation with the title instead of an author name in all three styles:

APA:

Remote work productivity trends [PDF]. (2024). Bright Horizons Research. https://example.com/reports/remote-work-2024.pdf

MLA:

"Remote Work Productivity Trends." Bright Horizons Research, 2024, example.com/reports/remote-work-2024.pdf. PDF.

In-text: Use a shortened version of the title instead of an author name — e.g., ("Remote Work," 2024) in APA, or ("Remote Work" 12) in MLA.

How to cite a PDF with no date

Use “n.d.” (no date) in place of the year:

APA: Chen, M. (n.d.). Remote work productivity trends [PDF]. Bright Horizons Research.

MLA: MLA generally omits “n.d.” and simply leaves the year out of the citation.

How to cite a government PDF or official document

Government and institutional PDFs are usually cited with the agency as the author:

APA:

U.S. Department of Labor. (2023). Occupational outlook handbook [PDF]. https://www.dol.gov/reports/outlook-2023.pdf

MLA:

United States, Department of Labor. Occupational Outlook Handbook. 2023, www.dol.gov/reports/outlook-2023.pdf. PDF.

How to cite a scanned or image-based PDF

Cite it the same way as any other PDF of that document type — the fact that it’s a scan doesn’t change the citation format. If the scan is of a physical book or printed report, cite it as you would that print source, and only add “[PDF]” or note the digital format if you specifically need to indicate you accessed a digitized copy rather than the physical original.

Frequently Asked Questions (FAQ)

Do I need to write “PDF” in every citation?

Not always — APA generally only adds “[PDF]” when the format matters for the reader to understand or locate the source (e.g., it’s not a standard journal article or webpage). MLA and Chicago are more flexible; adding “PDF” as a descriptor is optional but commonly done in academic writing for clarity.

How do I cite a PDF with page numbers if the PDF has no page numbers printed on it?

Use the PDF’s own page count as displayed in your PDF viewer (e.g., “page 5 of 20”) rather than any printed page numbers, and note this if your citation style requires clarity — some instructors accept “para. 3” (paragraph 3) instead when there’s no reliable page numbering.

How do I cite a PDF I downloaded from a database, not a website?

Cite the database instead of a general URL if your institution requires it — e.g., in APA: replace the URL with the database name if there’s no public URL, following your citation style’s specific database-citation rules.

Can I cite a PDF without a URL, like one emailed to me?

Yes — omit the URL and note how you obtained it if relevant to your assignment (e.g., “unpublished manuscript” or “personal communication,” depending on the source type and your citation style’s guidance for unpublished works).

What citation style should I use for a PDF?

It depends on your field: APA is standard in social sciences and education, MLA in humanities and literature, and Chicago in history and some publishing contexts. Check your assignment instructions or publication’s style guide if you’re unsure.

How do I find the PDF’s publication date if it’s not shown?

Check the PDF’s metadata: on Mac, open it in Preview → Tools → Show Inspector (Cmd+I) → General tab, which often shows a creation date. This isn’t always the same as the publication date, so verify against the document’s title page or copyright notice when possible.
