How To Cite a PDF

You can cite a PDF correctly by treating it as a book, article, or report first, then adding the URL or DOI in your chosen style.

In this guide, we’ll show you the core rule for how to cite a PDF, give you quick templates for APA, MLA, and Chicago, and share extra examples for trickier sources like government reports.

Here’s a fast reference for a simple PDF that looks like a book or report available online.

You’ll adjust these patterns based on the source type, but they give you a clear starting point for most PDFs.

A PDF is just a file format. You always cite the source based on what it actually is: A journal article, book, report, webpage, white paper, thesis, or something else.

Once you know the source type, you follow the usual rules for that style and then add the URL or DOI for the PDF version.

Here’s a simple checklist you can use for any PDF:

1. Identify the source type: Journal article, book, report, webpage, thesis, or other.

2. Gather key details: Author, title, year, publisher or organization, and page range.

3. Look for a DOI first. If there is none, use a stable URL.

4. Apply the rules for APA, MLA, or Chicago for that source type.

5. Stay consistent with spacing, punctuation, capitalization, and italics across your reference list.

If you treat “PDF” as a format, not a special category, your citations stay accurate and easy to check.

APA style uses an author-date system with in-text citations and a reference list. The structure shifts a bit depending on what your PDF contains.

1. Webpage PDF

Template

Author, A. A. (Year, Month Day). Title of webpage. Website Name. URL

Example

Johnson, M. (2023, March 15). Understanding climate change impacts. Environmental Research Institute. https://example.com/climate-report.pdf

2. Report Or Government Document (PDF)

Template

Author or Organization. (Year). Title of report (Report No. XXX if available). Publisher. URL

Example

Department of Education. (2023). Annual literacy assessment (Report No. ED-2023-01). Government Publishing Office. https://example.gov/literacy-report.pdf

If the author and publisher are the same organization, list the organization once as the author and omit it as the publisher.

3. Journal Article PDF

Template

Author, A. A., & Author, B. B. (Year). Title of article. Journal Name, Volume(Issue), pages. https://doi.org/XX.XXXX or URL

Example

Brown, L., & Davis, K. (2023). Digital transformation in education. Educational Technology Research, 45(2), 123-145. https://doi.org/10.1234/etr.2023.001

If a DOI exists, APA prefers the DOI over a URL.

4. Book or eBook (PDF)

Template

Author, A. A. (Year). Title of book. Publisher. URL

Example

Wilson, R. (2023). Modern research methods. Academic Publishers. https://example.com/research-methods.pdf

If you downloaded the PDF from a database and there is no DOI or stable URL, you can omit the URL entirely.

5. In-Text Citations in APA

Use parenthetical or narrative citations:

• Parenthetical: (Author, Year) or (Author, Year, p. X)

• Narrative: Author (Year) explains that... or According to Author (Year, p. X)...

For government bodies, use the organization name, for example (Department of Education, 2023).

MLA focuses on “containers”, which are the places that hold your source, such as websites or databases. For PDFs, the website or platform usually acts as the container.

1. Webpage PDF

Template

Author. “Title of Page.” Website Name, Date, URL.

Example

Martinez, Ana. “Sustainable Agriculture Practices.” Green Farming Initiative, 12 Apr. 2023, https://example.com/sustainable-farming.pdf.

If there is no individual author, you can start with the organization name or with the title.

2. Report Or Government Publication (PDF)

Template

Author or Organization. Title of Report. Publisher, Year. Website Name, URL.

Example

Environmental Protection Agency. Water Quality Assessment 2023. EPA, 2023. EPA.gov, https://epa.gov/water-assessment.pdf.

If the publisher is the same as the author, you can list the name once and skip it as the publisher.

3. Journal Article PDF

Template

Author. “Article Title.” Journal Name, vol. XX, no. X, Year, pp. XX-XX. Database Name, URL.

Example

Chen, Wei. “Machine Learning Applications.” Computer Science Quarterly, vol. 28, no. 3, 2023, pp. 45-62. Academic Search, https://example.com/ml-applications.pdf.

For PDFs downloaded from databases, MLA often includes the database as the container name.

4. Book or eBook (PDF)

Template

Author. Title of Book. Publisher, Year. Website or Platform Name, URL.

Example

Thompson, Sarah. Digital Marketing Strategies. Business Press, 2023. Publisher Direct, https://example.com/marketing-book.pdf.

5. In-Text Citations in MLA

MLA uses author-page citations:

• With pages: (Author Page), for example, (Martinez 23).

• Without pages: (Author) or the organization name, for example, (Environmental Protection Agency).

You do not need the year in the in-text citation.

Chicago has two systems: notes-bibliography and author-date. Humanities fields often use notes-bibliography, so we’ll focus on that.

1. Downloaded eBook (PDF)

Footnote

Author, Title of Book, PDF (City: Publisher, Year), page.

Bibliography

Author. Title of Book. PDF. City: Publisher, Year.

Example

1. Rebecca Foster, Urban Planning Principles, PDF (New York: City Press, 2023), 87.

Foster, Rebecca. Urban Planning Principles. PDF. New York: City Press, 2023.

2. eBook Consulted Online (PDF)

Footnote

Author, Title of Book (City: Publisher, Year), page, URL.

Bibliography

Author. Title of Book. City: Publisher, Year. URL.

Example

1. Michael Torres, Climate Science Today (Boston: Science Publishers, 2023), 156, https://example.com/climate-science.pdf.

Torres, Michael. Climate Science Today. Boston: Science Publishers, 2023. https://example.com/climate-science.pdf.

3. Webpage Or Online PDF

Footnote

Author, “Title of Page,” Website Name, date, URL.

Bibliography

Author. “Title of Page.” Website Name. Date. URL.

Example

1. Lisa Park, “Renewable Energy Trends,” Energy Research Hub, March 20, 2023, https://example.com/energy-trends.pdf.

Park, Lisa. “Renewable Energy Trends.” Energy Research Hub. March 20, 2023. https://example.com/energy-trends.pdf.

4. Report Or White Paper (PDF)

Footnote

Organization Name, Title of Report (City: Publisher, Year), page, URL.

Bibliography

Organization Name. Title of Report. City: Publisher, Year. URL.

Example

1. National Health Institute, Public Health Assessment 2023 (Washington, DC: NIH, 2023), 34, https://nih.gov/health-assessment.pdf.

National Health Institute. Public Health Assessment 2023. Washington, DC: NIH, 2023. https://nih.gov/health-assessment.pdf.

5. Footnotes vs Author-Date Basics

• Notes-bibliography: uses numbered footnotes and a full bibliography.

• Author-date: uses brief in-text citations (Author Year, page) plus a reference list.

If your department uses author-date, the structure looks closer to APA.

Citing PDFs is easier when you can search, mark, and organize them properly. That’s where Smallpdf features fit into your research process.

• Use OCR in PDF Converter to turn scanned PDFs into searchable text, so you can find names, dates, and page references quickly.

• Add page numbers with Number Pages if the document does not have them, which makes your citations more precise.

• Compress PDF to reduce file size before you share sources with classmates, supervisors, or co-authors.

• Merge PDF to combine chapters or related reports into one file, then cite sections more efficiently.

• Annotate with PDF Annotator to highlight key quotes and add citation notes in the margins.

One graduate student told us that using OCR on historical scans cut hours from their citation work, because they could search for names and dates instead of reading page by page.
