How many pages is that PDF? Sounds trivial. Opening 30 PDFs one at a time to find out isn't.
There are three faster ways depending on whether you've got one file, a folder, or a batch process.
One file, any reader
Open the PDF in any reader. The page count appears next to the page navigation — "Page 1 of 47". On Mac, the Finder Get Info pane shows the count without opening the file.
On Windows, hovering the file in Explorer shows a tooltip with the count if the file is indexed.
Many files, file manager view
In Finder, set the view to List or Columns and add the Pages column (View → Show View Options). Every PDF in the folder lists its page count.
Windows Explorer can also show page count as a column — right-click the column headers, More, Pages. Useful for inventory pass over a folder.
Quick check in the browser
Drop the file into Flint's editor and the thumbnail sidebar shows every page. The count is visible at the bottom of the panel.
Bonus: at this point you can also reorder, split, or delete pages without re-opening anything.
FAQ
Why does my PDF have more pages than I expected?
Often blank pages added by the source application (one per section break in Word). Remove blank pages to tidy up.
Is there a max page count for a PDF?
Technically yes, but it's astronomical. Practical limits come from reader performance — files over a few thousand pages get slow to scroll.
Can I check page counts without opening files?
Yes, via the file manager column or command-line tools (`pdfinfo` on Linux, `mdls` on Mac for the page count attribute).
Why do some readers show different page numbers?
Some readers count physical pages; some respect custom numbering (e.g. roman numerals for front matter). Both are correct — they're measuring different things.
Page count is a 5-second check in any modern reader. Drop your file into Flint's editor to see the count, the layout, and act on it in one place.
