Drop a PDF and read its title, author, page count and dates instantly in your browser. Uses pdf.js; clear message if it fails. Free.
What this tool does
Before citing a PDF, you need its real metadata: the title as stored in the file, the author, how many pages it has, and when it was created. Filenames lie — ‘paper_final_v2.pdf’ tells you nothing. This extractor reads the PDF’s embedded metadata in your browser with pdf.js and shows it in a clean list, plus a ready-to-paste citation starter. The file never leaves your computer.
Why it matters
Good citations do quiet work. They let a reader find every source you used, they show that your argument rests on real evidence rather than memory, and they protect you: a clean reference list is much harder to challenge than a vague one. Most marks lost on referencing are not lost on difficult sources. They are lost on small, repeated slips — a missing year, a swapped initial, a title in the wrong case — that a quick tool pass catches before submission.
How to use it
- Choose a PDF file.
- Click Read metadata.
- Copy the citation starter.
Worked example
A PDF with metadata Title ‘Clean Water Systems’, Author ‘Patel, R.’, 24 pages gives: Title: Clean Water Systems | Author: Patel, R. | Pages: 24 | Citation starter: Patel, R. Clean Water Systems. The tool’s demo formats exactly that record.
Tips for good results
If Title is blank, check the first page: the real title is usually there, and you can cite it even when the file metadata is empty.
Work from the source itself, not from another paper’s copy of it. And keep one style for the whole list: a single mixed entry undermines an otherwise perfect bibliography.
Honest limits
Metadata is only as honest as the file: many PDFs carry empty or wrong Title/Author fields, and scanned PDFs may carry none at all. The tool shows what is stored, and says so when a field is missing, rather than inventing it. It needs pdf.js to load from its CDN.
Common mistakes to avoid
Common mistakes to avoid: copying a reference from another paper without checking it against the original, trusting a PDF filename for the title or year, and mixing two styles in one list. Each of these looks harmless alone and careless together. Run the tool, read its output once, and compare it with the source itself before you paste it into your document.
Before you submit
Run through this short check before you submit: is every author name spelled as it appears on the source, is every year present and correct, and does every in-text citation have a matching entry in your reference list? Read the list once from top to bottom rather than skimming it. Most referencing errors are found in that single slow read, and fixing them there is far cheaper than fixing them after a reviewer finds them. If one entry still looks odd after that read, check it against the original source before you change anything else.
Frequently asked questions
Is this tool really free?
Yes. It runs in your browser on this page, with no account and no payment. Your files stay in your browser; only the tool library loads from its CDN.
Do I still need to check the result?
Yes, once. Tools apply rules; they cannot verify facts about your source. Compare the output with the source itself before submitting.
Can I use the output in my paper?
Yes. The output is a formatted reference or analysis for your own work. Keep the source’s facts accurate and the formatting consistent across your list.
What if the tool’s output differs from my style guide?
Trust the style guide. Tools encode the common rules of a style; your university or journal’s own sheet wins every disagreement. Use the tool to do the routine work, then apply the local rule where it differs.
