How PDF word counting works
A PDF word counter extracts every piece of selectable text from a PDF, page by page, and reports the word count, character count, and page count — plus, on this tool, an estimated reading time and a keyword-density breakdown of the words that appear most often. It runs the whole thing directly in your browser, so the file itself never has to leave your device.
Word and character counts work the same way a word processor counts them: whitespace splits the text into words, and every character — including spaces — is tallied for the character total, with a second count showing the character total without spaces for anywhere a character-limited field means that number instead. The page count comes straight from the document's own structure, so it's exact regardless of how the text extracts. Reading time is estimated from the word count at a standard adult reading pace, and the Top Words panel ranks every word in the document by frequency, showing each one's share of the total word count — common function words like "the" and "and" are filtered out by default so the list surfaces actual keywords, not the words every document has the most of. For documents with more than one page, an expandable per-page breakdown shows exactly how the words are distributed across the file.
It only works on text-based PDFs — documents where the words themselves are stored as real text, not as pixels in a scanned image. Most PDFs exported from Word, Google Docs, or similar tools qualify; scanned paper documents typically don't, since there's no text layer to read until OCR is applied.
Common use cases
- Checking whether a document meets a word count requirement for submission
- Estimating reading or presentation time before sharing a document with others
- Spotting overused words or checking keyword density before publishing SEO content as a PDF
- Quickly confirming a PDF's page count without opening it in a full viewer
- Comparing the length and vocabulary of drafts before finalizing a document
If you need the actual extracted text — not just the counts — the PDF to Text tool on this site pulls out the full plain text and lets you copy or download it.

PDF Word Counter — frequently asked questions
No — it counts real, selectable text. A scanned PDF has no underlying text layer, so the count comes back as zero, and the tool will tell you that directly rather than leaving you staring at an unexplained zero. Run it through the OCR PDF tool first to give it a text layer, then count it here.
By extracting all selectable text from every page and splitting it on whitespace — the same basic method most word processors use. A hyphenated term like state-of-the-art counts as one word, matching how Microsoft Word counts it, since the text is never broken apart at the hyphen.
"Characters" counts every character including spaces and line breaks; "No spaces" strips whitespace out first. Style guides and character-limited fields (a form, a caption, a subject line) almost always mean the no-spaces number when they say "character limit," so both are shown rather than making you guess.
Keyword density is how often a word appears, shown as a percentage of the document's total word count. The Top Words section ranks every word by frequency and shows both, with common function words (the, and, of, and similar) filtered out by default so you see actual content words first — check "Include common words" if you want the unfiltered list.
Word count divided by 225 words per minute, a commonly used average adult silent-reading speed, rounded to the nearest minute. Treat it as a rough guide — actual reading time varies a lot with content density, unfamiliar terminology, and how many diagrams or tables break up the text.
It counts all extractable text regardless of layout, so the word and character totals stay accurate. What can shift is reading order — a complex multi-column or table-heavy layout may extract in a sequence that doesn't read top-to-bottom the way it visually appears, which mainly affects the per-page breakdown's usefulness for that page, not the overall counts.
No fixed limit — very long documents simply take a little longer since everything processes on your device rather than a server. A few-hundred-page report is fine; you'll just see the progress bar run a little longer than a one-page letter would.
No. The file is read and its text extracted entirely inside your browser tab using a JavaScript PDF library — the file, its text, and every count stay on your device and are never sent to a server.
