How to Remove Blank Pages from a PDF
Scanning a stack of paper through an automatic feeder almost always picks up a few blank pages — the back of a one-sided sheet, a separator page, or a page that just didn't scan cleanly. Finding and deleting them one by one is tedious, especially in a long document.
Why blank pages show up in scanned PDFs
Most scanners default to duplex (two-sided) scanning even when your paper is only printed on one side, which adds a blank page for every sheet. Separator sheets, cover pages, and the occasional scanning glitch add a few more. In a 40-page scan, that can mean a dozen blank pages mixed in.
How to remove blank pages automatically
The tool checks each page's content and flags the ones that are effectively empty, so you don't have to scroll through and check manually.
- Upload your scanned PDF
- Let the tool scan each page and detect the blank ones

What counts as "blank"
A page with a stray mark, a faint scanner line, or a bit of background noise from the glass isn't always perfectly empty — detection is tuned to catch pages that are blank for practical purposes, not just pages with zero pixels different from white. The remaining pages keep their original scan quality; nothing about them is re-compressed or altered.
Frequently asked questions
Will it accidentally remove a page with faint content?
Detection looks for pages that are blank for practical purposes, but it's worth a quick check of the flagged list before downloading, especially for scans with very light handwriting or faint stamps.
Does this reduce the quality of the remaining pages?
No. Removing blank pages doesn't touch the remaining pages — they keep their original scan quality.
Is my PDF uploaded to a server?
No. Detection and removal run entirely in your browser, so your file never leaves your device.
