Checking how many pages a PDF has is one of the most straightforward PDF tasks — every viewer shows you this information, and several methods let you check it without even opening the file. Here's where to look in each common environment.
In Adobe Reader and Acrobat
Adobe Reader shows the page count in two places. The most visible is the page indicator at the bottom of the screen — it displays the current page and total pages in the format "1 / 24" where 24 is the total. The second place is File > Properties > Description tab, which lists the exact page count in the document metadata.
The Properties method is useful when you need the page count without scrolling to the document — just open Properties immediately after opening the file. It also shows other useful metadata like file size, creation date, and the application used to create the document.
In Chrome and Other Browsers
Chrome's built-in PDF viewer shows the page count in the toolbar at the top of the page — the same "current / total" format as Adobe Reader. Open the PDF in Chrome by dragging it into a browser window or right-clicking and choosing Open With > Chrome. The page count appears immediately in the toolbar.
Firefox, Edge, and Safari all display page counts similarly in their built-in PDF viewers. The exact position of the indicator varies slightly between browsers but it's always visible in the toolbar area.
On Mac With Apple Preview
Preview shows the page count in the thumbnail sidebar — the sidebar displays all page thumbnails and the total count is visible by scrolling to the bottom. For a quick count without scrolling, go to View > Thumbnails to open the sidebar and count is visible, or check Tools > Show Inspector (Cmd+I) which shows document information including page count.
On Mac, you can also check page count without opening the file: right-click the PDF in Finder and choose Get Info. The Info panel shows the file's metadata including page count if it's stored in the file's extended attributes — this works for most standard PDFs.
Without Opening the File: Windows
On Windows, you can check the page count from File Explorer without opening the PDF. Right-click the file and select Properties > Details tab. For PDF files, Windows sometimes displays the page count here if it's stored in the file metadata. Alternatively, hover over the file in File Explorer — a tooltip may show basic file information including page count for indexed PDFs.
The Details tab method works more reliably after Windows has indexed the file. If you just downloaded or created the PDF, the metadata may not appear until indexing catches up. Opening the file in any viewer is the most reliable immediate method.
Checking Page Count on Mobile
On iPhone, opening a PDF in the Files app or any PDF viewer shows the page count in the navigation bar — typically as "Page X of Y" or a progress indicator showing how far through the document you are. Scrolling to the last page and noting the number is always an option if the count isn't displayed directly.
On Android, Google Drive displays page count in the file details view. Open Google Drive, long-press the PDF file, tap the three-dot menu, and select Details — the page count appears in the file information panel.
When You Need Page Count for Multiple Files
If you need to check page counts across many PDF files — for billing, for archiving, or for workflow planning — opening each one individually is time-consuming. Adobe Acrobat Pro's Action Wizard can run a batch process that exports metadata including page counts from a folder of PDFs. For non-Acrobat users, a PDF Editor or command-line tool like pdfinfo (part of the Poppler utilities, free and cross-platform) can report page counts for multiple files in one operation: running "pdfinfo filename.pdf" returns the page count along with other document metadata in seconds.
