What does this PDF Page Counter do?

This free online PDF page counter tells you exactly how many pages are in any PDF file — instantly and without uploading anything. Drop one or more PDFs into the tool and it reads the page count directly from the file's internal page tree using pdf-lib, a fast open-source JavaScript library that runs entirely in your browser.

You can count pages in a single PDF or in a whole batch of files at once. Each file's page count is listed separately, and the tool also shows the combined total across all files plus the average pages per file. This makes it easy to audit a folder of PDFs, estimate printing costs, or verify that a document is as long as it should be.

Everything runs locally. Your PDF files never leave your device — there is no upload, no server processing, and no data storage. Close the tab and it's gone.

How to count pages in a PDF

  1. Select a PDF file from your device. Drag and drop one or more PDFs into the upload zone, or click Select PDF Files and choose them from your device. You can select multiple files at once.
  2. Wait for the browser to analyze the document. The tool reads the PDF's internal page tree locally using pdf-lib. No page rendering is required, so even a 1000-page document is counted in milliseconds.
  3. View the exact total page count instantly. Each file's page count is displayed in a list, along with the combined total and the average pages per file. Copy the results or start again whenever you like.
