Count the number of pages in a PDF and see its file size, entirely in your browser.
How to use the PDF Pages
Click Choose PDF and pick a file.
The page count is read in your browser.
See the number of pages and the file size.
A PDF page counter instantly reports how many pages a PDF has, along with its file size, without uploading the file anywhere. The count and size appear the moment you choose a file, with no waiting on an upload and no need to open a heavy PDF application just to check.
It answers a small but frequent question: how long is this document, really? That matters before you print it, attach it where there is a page or size limit, or split it into parts.
Knowing the size as well as the page count is useful when a form or email caps attachments, since a high page count or large images can push a file over the limit.
It reads only what it needs, so even large documents report quickly, though very large files use more memory in the browser tab.
Everything runs locally in your browser with pdf-lib, so the file never leaves your device and the check is completely private. There is nothing to install.
