How to remove blank pages
- Choose your PDF. Blank pages are found and selected for you.
- Check them: tick or untick pages, or choose how strict "blank" should be.
- Press Remove selected pages and download.
How blank pages are found
- Each page is drawn small and its share of dark pixels is measured. The outer edge is ignored, where scanners leave shadows.
- "Empty with a few specks" suits most scans. "Almost empty" also catches pages with just a page number or a line.
- Small pictures of the pages that look blank are shown, so you can check before removing them.

常见问题
Can a page with very little text be removed by mistake?
Only if you choose "Almost empty". The pages are only selected; you can untick any page before removing.
Is my PDF uploaded?
