Frequently Asked Questions
Everything you need to know about counting words in PDF files
What does PDF Word Counter do?
PDF Word Counter reads the text layer of a PDF and reports the total number of words, characters (with and without spaces), and sentences, with a per-page breakdown.
What format is the output?
The report downloads as a JSON file with totals and per-page statistics, so you can review or feed it into another tool.
Does this change my PDF?
No. The tool only reads text from the PDF and produces a separate JSON report. Your original document is not modified.
Are my files uploaded to a server?
No. Word counting runs locally in your browser using pdf.js, so your PDF never leaves your device.
Does this work on scanned PDFs?
No. This tool counts text from the embedded text layer. Scanned image-only PDFs need OCR before words can be counted.
How are words counted?
Words are counted by splitting the extracted text on whitespace, which matches the common word count convention used in word processors.
How accurate are the sentence counts?
Sentence detection uses standard end-of-sentence punctuation. Counts are a useful estimate but may differ from a manual review for documents with unusual punctuation or formatting.
Can I count words in a password-protected PDF?
Encrypted or password-protected PDFs need to be unlocked before their text can be read and counted.
Do I need an account?
No. PDF Word Counter is free to use without sign-up, login, or installation.
Is this tool completely free?
Yes. You can count words in PDF files for free with no watermarks or limits.
