This free pdf word analyzer scans any PDF and instantly calculates its readability using six established formulas — Flesch Reading Ease, Flesch-Kincaid Grade, Gunning Fog Index, SMOG, Coleman-Liau Index, and Automated Readability Index — alongside detailed word statistics most tools skip entirely. Simply upload your PDF, and it extracts the text to show word count, sentence count, unique words, lexical diversity, and estimated reading time, plus a breakdown of the most frequent words and how many words appear on each page.
You can exclude specific pages, like a references or appendix section, so they don't skew your overall score, then re-analyze instantly. Every report can be exported as a CSV file for record-keeping or further analysis. Everything runs entirely inside your browser, so your document is never uploaded anywhere.

How This PDF Word Analyzer Works
Getting a full readability checker report on a PDF takes just a few steps. Here's how it works:
- Upload your PDF — click the upload area or drag and drop any PDF file from your device.
- Text is extracted and analyzed instantly — the tool reads every page and calculates word counts, sentence counts, and six readability formulas.
- Refine your results — exclude pages like references or appendices from the score, then click "Re-analyze" to update instantly.
- Review and export — check the readability grade, word frequency, and per-page breakdown, then export the full report as a CSV file.
Why Use This PDF Word Analyzer
Most readability tools only accept plain text and ask you to copy-paste content by hand, which gets tedious fast for anything longer than a page. This word count tool reads PDFs directly, extracting text from every page automatically so you can run a full readability checker on an entire report, thesis, or manual in one pass instead of retyping it elsewhere.
It also goes further than a single readability number. Along with Flesch Reading Ease and five other grade-level formulas, you get word frequency data, per-page word counts, and lexical diversity — details that help you see not just how hard a document is to read, but where the difficulty is concentrated.
The Plain Writing Act of 2010 directs U.S. federal agencies to write public-facing material in plain language, and guidance under that law commonly points to an 8th-grade Flesch-Kincaid level or lower as a practical target — a useful benchmark whether or not you're writing for a government audience. Because everything runs locally in your browser, your document is never uploaded anywhere, and the full report can be exported as a CSV for your records.
Who This PDF Word Analyzer Is Built For
- Content writers and bloggers — checking that an article's readability score matches their audience before hitting publish.
- Teachers and educators — verifying that reading material sits at the right grade level for their students.
- Students and researchers — running a readability checker on a thesis or paper draft before submission.
- UX and technical writers — keeping documentation and manuals in plain, accessible language.
- Marketing and communications teams — testing website copy, brochures, or reports against a target reading level.
Tips for Getting Accurate Results
- Exclude reference and citation pages — bibliographies and footnotes often contain dense, non-prose text that can unfairly drag down your overall readability score.
- Aim for grade 6-8 for general audiences — this range, often cited in plain-language guidance, works well for most web content, blog posts, and public-facing material.
- Treat passive voice as an estimate — the detector flags common patterns but isn't a full grammatical analysis; use it as a rough guide, not a precise count.
- Scanned PDFs without selectable text won't work — this tool reads embedded text, so image-only scans need OCR first before they can be analyzed.
- Check the per-page breakdown for outliers — a single dense page can pull down an otherwise readable document's average score.
FAQs
What does a pdf word analyzer actually measure?
It extracts the text from your PDF and calculates word, sentence, and character counts alongside six readability formulas that estimate how easy or difficult the writing is to understand.
Is this tool free to use?
Yes, this tool is completely free with no signup required. You can upload a PDF, run a full readability check, and export the report without creating an account.
What's a good Flesch Reading Ease score?
Scores of 60-70 are considered standard, easily understood prose for most adults. Higher scores mean easier reading, while scores below 30 typically require a college-level education to follow comfortably.
Is my PDF uploaded to a server?
No. This tool processes your PDF entirely inside your browser. Your file is never sent to a server, which keeps your document private with no practical file size limit.
Can I exclude certain pages from the analysis?
Yes. Enter page numbers or ranges, like references or appendix sections, in the exclude field and click "Re-analyze" to recalculate your score without them.
Why do I get six different readability scores instead of one?
Each formula weighs sentence length and word complexity slightly differently. Showing all six, plus an average grade level, gives a more reliable picture than relying on a single number.
Does this work on scanned PDFs?
Only if the PDF has selectable, embedded text. Image-only scans have no extractable text for the analyzer to read, so they need OCR processing first.
What's included in the CSV export?
The exported report includes every statistic, all six readability scores, your top frequent words with counts, and a full word-count breakdown for each page.

Readability formulas are statistical estimates based on sentence length and automated syllable counting, not a measure of writing quality, accuracy, or clarity, and results can vary slightly between tools depending on text extraction and counting methods.
