How to Count Words in a PDF (3 Easy Ways)

PDFs are everywhere — essays, reports, contracts, ebooks — but unlike a Word document, a PDF shows no word count anywhere on screen. If a teacher, client, or editor asks “how many words is it?”, you have to fetch that number yourself.

The good news: it takes less than a minute. Here are three easy ways, plus what to do when a PDF refuses to cooperate.

Method 1: Upload the PDF to a Word Counter Tool (Fastest)

The quickest method is to let a tool read the file for you:

  1. Open the free Word Counter tool.
  2. Upload your PDF file — the tool extracts the text from the PDF right in your browser.
  3. Read your results instantly: word count, character count, sentences, paragraphs, and even reading and speaking time.

This method is ideal when you need more than a bare word count — for example, checking how long a document takes to read aloud, or confirming an essay fits a limit before you submit it. There is nothing to install, and the same tool also accepts Word documents (.docx), plain text files, spreadsheets, and CSV files if your document is not a PDF.

Method 2: Copy and Paste the Text

If your PDF is already open, the low-tech route works fine:

  1. Open the PDF in your usual reader.
  2. Select all the text (Ctrl+A on Windows, Cmd+A on Mac) and copy it.
  3. Paste it into the Word Counter and read the count.

One caution: copying from a PDF sometimes brings along extra line breaks, running headers, or page numbers that repeat on every page. Those add a few stray “words” to the count. For a rough number this does not matter; for an exact submission count, Method 1 gives a cleaner read of the document’s text.

Method 3: Open the PDF in Word or Google Docs

Both Microsoft Word and Google Docs can open a PDF and convert it into an editable document — and once it is converted, their built-in counters work as normal:

  • Microsoft Word: open the PDF, let Word convert it, then check the word count on the status bar (or via Review → Word Count).
  • Google Docs: upload the PDF to Google Drive, open it with Google Docs, then go to Tools → Word count.

The trade-off is accuracy: conversion can shuffle complex layouts, move footnotes, or drop text in tables and text boxes. For simple, text-based PDFs it is perfectly fine; for heavily formatted documents, compare with Method 1 if the number really matters.

The Scanned PDF Problem (And What to Do)

There is one kind of PDF none of these methods can read directly: a scanned PDF. When a document is scanned, each page is saved as a picture of text rather than actual text. The page looks like words to you, but to a computer it is just an image — there is no text layer to count. Our Word Counter is honest about this: if an uploaded PDF has no readable text, it tells you instead of inventing a number.

What can you do?

  • Ask for the original file. If someone exported the document to PDF, the original Word or Google Docs version will count in seconds.
  • Run the PDF through OCR first. OCR (optical character recognition) software reads the pictures of letters and turns them back into real text. Save the result as a new PDF or document, then count it with any method above. Google Docs’ open-and-convert route also performs OCR on scanned pages in many cases.
  • Check whether the text is selectable. Quick test: try to highlight a sentence with your mouse. If you can select the words, the PDF has real text and will count normally. If you can only drag a box over the page like an image, it is a scan.

Why Word Counts Can Differ Slightly Between Tools

Do not panic if two methods give you numbers that are a few words apart. Small differences are normal, because tools make slightly different decisions about things like:

  • Hyphenated words — is “well-known” one word or two?
  • Headers, footers, and page numbers — some tools include the repeated text on every page, others leave it out.
  • Text boxes, captions, and footnotes — depending on the tool, these may or may not be counted.
  • Numbers and symbols — some counters treat a standalone number or symbol as a word, others skip it.

For essays and articles these differences are tiny. What matters is using one consistent method. If you are aiming at a page-based goal instead, our guide on how many words are in a page helps you plan the length before you write.

Who Needs to Count Words in a PDF?

  • Students — checking an exported essay or assignment against a word limit before submitting.
  • Translators and editors — quoting a price for a PDF document, since translation is usually charged per word.
  • Writers and freelancers — confirming a delivered article, report, or ebook chapter matches the agreed length.
  • Job applicants — keeping a PDF resume or cover letter to a sensible length.

Frequently Asked Questions

How can I count words in a PDF for free?

Upload the PDF to the free Word Counter tool. It extracts the text in your browser and shows the word count instantly, along with characters, sentences, paragraphs, and reading time.

Why does my PDF show no readable text?

It is probably a scanned PDF — its pages are images rather than real text. Run it through OCR first, or open it with Google Docs so it can be converted, then count the converted version.

Does Adobe Reader show a word count?

Acrobat Reader does not offer a built-in word count on its own. The standard workarounds are the ones in this guide: a word counter tool, copy-paste, or converting the PDF in Word or Google Docs.

Will the count include headers and footers?

It can, depending on the method — pasted or extracted text often includes repeated headers, footers, and page numbers. If your count looks slightly higher than expected, that is the usual reason.

Can I count words in a PDF on my phone?

Yes — the Word Counter works in a mobile browser. Upload the PDF from your phone’s files and the count appears just as it does on a computer, with no app to install.
