# PDF Word Counter

Category: PDF

## How do I count words in a PDF?

Use this PDF word counter to read a digital PDF's selectable text and calculate its words, characters, sentences, reading time, and per-page totals. The document stays in your browser and is never uploaded. Image-only scans need OCR before their words can be counted.

The counter uses **PDF.js to read the text layer already stored in each page**, then applies Unicode-aware text segmentation in your browser. The per-page table helps you spot unusually dense pages, empty pages, or sections that may have been missed.

PDF files describe positioned text fragments rather than the paragraphs you see on screen. Headers, footers, tables, columns, and references are included when they exist in the text layer. The tool does not guess which sections a publisher or university excludes from an official limit.

## How to use it

1. **Choose a digital PDF** - Drop one PDF onto the counter or select it from your device. You should be able to highlight its words in a normal PDF viewer.
2. **Count the text** - Click Count words. PDF.js reads each page locally and shows progress while it builds the totals.
3. **Review the results** - Check words, characters, sentences, reading time, and the page-by-page breakdown. Empty pages are clearly flagged.
4. **Copy the summary** - Copy a plain-text report for a submission note, estimate, or editorial record, or clear the file and count another PDF.

## Who it's for

- **Students** checking whether a submitted essay or dissertation PDF stays near an assignment limit.
- **Editors and writers** sizing manuscripts, reports, and proofs when the source document is unavailable.
- **Translators** estimating document scope while keeping client files on their own device.
- **Researchers** comparing section density and finding pages with little or no selectable text.

## Expert note

Word totals can differ from Microsoft Word because a PDF stores text in positioned fragments. Hyphenation at line breaks, repeated headers, footers, and the document's reading order can all change the count. For a formal limit, use the submitting organization's stated method.

## Frequently asked questions

### Is my PDF uploaded to count its words?

No. PDF.js reads the selected document inside your browser, and CanDoYa does not receive the file or extracted text. The PDF engine code may load when you first use the counter, but your document is not sent with that request.

### Is the PDF word counter free?

Yes. You can count PDFs without an account, payment, watermark, or daily quota. Processing happens on your device, so there is no upload queue or converted file stored on a server.

### What are the file size and page limits?

The counter accepts one PDF up to 100 MB and 2,000 pages. Device memory and browser performance may set a lower practical limit, especially on phones. Split a very large PDF if your browser cannot finish it.

### Can it count words in a scanned PDF?

Only if the scan already has an OCR text layer. An image-only PDF contains pixels rather than selectable characters, so it will show zero readable words. Run OCR first, then count the searchable result.

### Why does the PDF word count differ from Word?

The applications may reconstruct line breaks, hyphenated words, tables, headers, and footers differently. This counter reads the PDF's text layer as stored. An exported Word document may merge or split fragments, so small differences are normal.

### Does the count include footnotes and references?

Yes, when those sections contain selectable text. The counter reports every readable word in the PDF and does not automatically exclude a bibliography, captions, headers, or footnotes. Use the per-page breakdown and your submission rules to interpret the total.

### Which languages can the PDF word counter read?

It uses the browser's Unicode-aware segmenter, so it can count many scripts when the PDF has correct character mappings. Counts for languages without spaces depend on browser segmentation support, and damaged or custom font maps can still produce incomplete text.

### Can it open a password-protected PDF?

No. Remove the password in a trusted PDF viewer first, if you have permission, then count the unlocked copy. The counter does not ask for or store PDF passwords.
