How to Cite a PDF: APA, MLA and Harvard
A PDF is a format, not a source type. How to tell if yours is an article, report, chapter or thesis, find its details, pick the page number and cite scans.
There is no such thing as "PDF format" in APA, MLA or Harvard. PDF is a container, the same one used for journal articles, government reports, dissertations, book chapters and lecture slides, and every style asks you to cite the work inside it.
So the real question is never "how do I cite a PDF". It is "what is this document, actually?" Answer that and the format follows.
Step 1: identify what you are holding
Open the first page and look for these signals, in order:
- A journal name, volume and page range in the header → it is a journal article. Cite it as one.
- A DOI (a string starting
10.) → almost certainly a journal article or a formally published report, and the DOI is the best identifier you can give. - An organisation's logo and a report number → a report. The organisation is the author.
- "A thesis submitted in partial fulfilment…" → a thesis or dissertation.
- An ISBN and a publisher → a book or a chapter from one.
- None of the above → treat it as a standalone document or web page.
Where the metadata hides
If the first page is unhelpful, three more places usually have what you need:
- Document properties. In most readers, File → Properties shows an embedded title, author and creation date. Treat the date with suspicion: it is often the date the file was generated, not published.
- The last page. Reports frequently put the imprint, publication date and report number in the back matter.
- The DOI. Paste it into a search and you get the full, authoritative record, which beats anything you can read off the page.
Step 2: apply the format for that source type
A journal article that happens to be a PDF
APA 7
MLA 9
Harvard
Note what is absent from all three: any mention that you read a PDF. See our full guide to citing journal articles.
A report from an organisation
APA 7
Harvard
If the report carries a report number, APA puts it in parentheses after the title, for example (Report No. 123). This WHO report has none.
A thesis or dissertation
APA 7 template
Lecture slides: the real exception
APA puts a description of the kind of work in square brackets after the title, such as [PowerPoint slides] or [Lecture notes], followed by the name of the learning platform. The bracket describes the work, not the file type:
APA 7 template: lecture slides
If the link only works for enrolled students, say where it lives rather than pretending it is public.
Step 3: get the page number right
This trips up more students than the reference format does. A PDF has two sets of page numbers: the ones printed on the page, and the ones your viewer counts. They are usually different, because covers, blank pages and roman-numbered front matter all shift the count.
The two numbers
Always cite the printed number. It is the one that exists in every copy of the document, including the paper one your marker might pull off a shelf. If there are no printed numbers at all, point to a heading or a paragraph number instead.
Awkward cases
No author
Work down the ladder: named person, then publishing organisation, then title. Most authorless PDFs are institutional, so the issuing body takes the author position: a ministry, a company, a university. Only when no organisation is identifiable does the title move forward.
No date
Use n.d. in APA and no date in Harvard (Cite Them Right). Resist the temptation to use the file's creation date from document properties, or a copyright year in the footer, and neither tells you when the content was published.
A scanned PDF with no text layer
If you cannot select the text with your cursor, the file is an image and no tool can read it automatically, including ours. You will have to type the details in by hand. It is also worth checking whether a proper digital version exists: scanned copies are often unofficial re-distributions, and the published original is a better source in every respect.
A paywalled PDF
Cite it normally. Your reader does not need to be able to open the link for the reference to be valid: that is what the DOI is for. Never substitute a link to a pirated copy.
Let the file fill in its own details
Most of what you need is already inside the document. CitApp reads a PDF in your browser (the PDF file itself is not uploaded; the text is read on your device and the relevant parts are sent to CitApp to identify the source) and pulls out the title, authors, year and DOI, then formats the reference in APA, MLA, Harvard or any of our 150+ styles. If you save a quotation from it, CitApp also works out which printed page the passage came from, so the page number in your citation is the one your reader can actually find.

Frequently asked questions
Do I need to write [PDF] in the citation?
Almost never. APA 7, MLA 9 and Harvard all want you to describe what the work is, not what file it arrived in, so a journal article saved as a PDF is cited exactly like a journal article. The nearest thing to an exception is lecture material. APA puts a bracketed description of the kind of work after the title, such as [PowerPoint slides] or [Lecture notes], and that bracket names the work, not the file type.
How do I cite a PDF with no author?
Move down the ladder: a named person first, then the organisation that published it, then the title. Most authorless PDFs are corporate or government reports, so the issuing body becomes the author: the Department of Health, the World Bank, the university. Only when there is no identifiable organisation does the title move into the author position.
Should I use the PDF page number or the printed page number?
We recommend the printed page number: the one shown on the page itself. Your reader needs a number they can find in any copy of the document, and a PDF viewer's counter is often offset by cover pages and front matter, so page 12 of the file may be page 4 of the report. The style guides do not rule on viewer numbers versus printed numbers, so this is our advice rather than a style rule. If the document has no printed numbers at all, point to a heading or a paragraph number instead.
How do I cite a PDF from my university's course site?
If the document exists publicly elsewhere (a published article, a public report), cite that original version, because a Canvas or Blackboard link only works for people enrolled in the course. If it is genuinely course material written by your lecturer, cite it as unpublished course material with the instructor as author, the course code, and the institution.
