How to cite a PDF: APA style, MLA, Chicago, and more

For an article or book, you can cite a PDF as a reference. Here’s what you need to know.

Citing a PDF correctly is essential whether you're writing a research paper, article, report, or any other project that requires proper attribution. PDFs can represent anything: a scanned book chapter, a downloaded report, a journal article, a white paper, or a custom document created for the web. Because PDFs vary widely in format and source, the citation style you use must match the type of content the PDF represents.

This guide explains how to cite a PDF in APA, MLA, and Chicago style, and covers common questions like how to reference a specific PDF or how to cite a PDF with no author.

Key takeaways:

• You can cite a PDF in APA, MLA, or Chicago style by identifying the author, title, publication date, publisher, and URL — the same elements used for books, articles, and web pages.
• APA citations for PDFs follow the same format as citing a webpage.
• MLA and Chicago styles allow more flexibility and can accommodate PDFs with missing information, multiple versions, or unclear publication details.
• When a PDF has no author, no date, or no clear source, you can still create a complete citation by following the rules for missing information in each style guide.

How to cite a PDF: General rules

Before choosing a citation style, it’s important to identify the original source of the PDF. A PDF might be a scanned book, a downloaded article, a government report, or a custom document created for the web. If you can determine the original source, cite that source directly. If not, cite the PDF itself as thoroughly as possible.

These guidelines help answer questions like "What citation goes with this PDF" or "How do I cite a downloaded article?

What to identify:

• Author
• Title
• Publication date or year
• Publisher or organization
• Page range (if applicable)
• URL (without hyperlink formatting)

If the PDF was created specifically for the web, cite as much information as is available.

How to cite a PDF in APA Style.

APA (American Psychological Association) style is commonly used in the social sciences, education, and professional writing. Citing a PDF in APA follows the same structure as citing a webpage, so once you are comfortable with web citations you should be easily able to reference or cite a PDF APA style.

APA citation elements:

• Author
• Year
• Title
• Publication or source
• URL (not hyperlinked)

APA format example:

Author’s Last Name, First Initial. (Year). Title of document (italic). Publication or Organization. URL

If you need to generate an APA citation from a PDF, you can use Acrobat AI Assistant or other such online tools and chat agents with questions like "Can you cite this document?" or "What citation goes with PDF?".

How to cite a PDF in MLA Style.

MLA (Modern Language Association) style is widely used in the humanities. MLA is flexible and allows you to include or omit details depending on relevance. You may include an access date, and if the PDF is a downloadable version, you can add “PDF Download” at the end of the citation.

MLA format example:

Author’s Last Name, First Name. “PDF Title.” Website Name, Day Month Year, URL or DOI.

If citing a PDF book, italicize the title instead of using quotation marks. Remove “https://” or “http://” from the URL. Use a hanging indent for all MLA citations.

How to cite a PDF in Chicago Style.

Chicago style is commonly used in business, fine arts, and some humanities fields. Many people now use AI to help with creating Chicago citations; however, it is always helpful to check the work of AI tools to ensure correct formatting. To cite a PDF in Chicago style, use the standard citation format for the source type and add the PDF's URL or DOI.

Chicago format example:

Author’s Last Name, First Name. “PDF Title.” Website Name (italic), Month Day, Year. URL or DOI.

If citing an eBook downloaded as a PDF, cite it like a book and add “PDF.” at the end.

How to cite a PDF with no author

If a PDF has no author, use the title in the author position. This applies across APA, MLA, and Chicago styles.

General format:

Title of PDF. (Year). Publisher or Organization. URL
