Delete blank pages from PDF automatically
Auto-detect and remove every blank page from your PDF. No manual page-by-page review. Free.
Scanned documents often have blank pages between sections — separators that came through the scanner. Manually flipping through to find them is tedious. We render every page at low DPI, measure pixel density, and remove anything that's effectively empty.
Adjust the sensitivity threshold if some near-blank pages (faint stamps or footers) need to be kept or removed.

Frequently asked questions
How does it decide a page is blank?
We render each page to a small thumbnail and measure both mean brightness and standard deviation. A page is 'blank' if it's almost-all-white (mean ≥ 99% bright) AND has very low variance (no consistent gray content). Pages with stamps, watermarks, or even faint text won't trigger.
Can I tune the threshold?
Yes — set it lower if you want to also remove near-blank pages with very faint marks, or higher to be even stricter.
Will it remove my section dividers if they're mostly white?
Section divider pages with a chapter title (text on the page) are not blank — text creates variance and the heuristic spares them. Truly empty 'flip page' separators get removed.
