Frequently asked questions
- How does it decide a page is blank?
- Each page is rendered and checked for ink coverage. Pages with essentially no content are removed; light scanner speckle and faint edges are tolerated so real pages are kept.
- Does my file get uploaded?
- No. Pages are analyzed entirely in your browser — nothing leaves your device.
- Will kept pages lose quality?
- No. Detection uses a quick low-resolution render, but the pages that are kept are copied through unchanged, staying crisp and selectable.
Clean scans in one click
Scanning a double-sided stack often leaves an empty page behind every sheet that had a blank back. Remove Blank Pages scans the document, finds those empties, and drops them — leaving a tidy file, entirely in your browser.
Careful detection
Each page is rendered at low resolution and measured for ink coverage, with a tolerance for scanner speckle and faint edges so genuine (but sparse) pages aren't mistaken for blanks. Kept pages are copied through untouched, so they stay sharp and their text stays selectable.
Notes and limits
If nothing looks blank, your file comes back unchanged and you'll be told so. Everything runs locally, so even sensitive scans never leave your device.
How the detection actually works
Each page is rendered to a small low-resolution bitmap and measured for how much of it is covered by ink versus bare white space. A page that comes back essentially empty, no text, no image data, nothing above the tolerance threshold, is flagged as blank. The tolerance exists specifically because real scanners leave marks on genuinely blank sheets: a faint line from a dusty glass, a stray speckle near the edge, a slight gray cast across the whole page. Those are allowed through so a technically-blank-but-imperfect scan isn't mistaken for real content, and so a nearly-empty page with a page number or a single line of text is correctly kept.
Where detection can be fooled
A page that's blank except for a running header, footer, or page number will usually still register as having content, since that's real ink on the page — it won't be removed even though a human might call it "blank." Always skim the result before treating it as final, especially on a document where a wrongly-removed page would matter.
When this comes up
The classic case is a duplex scan run through a simplex-only scanner, or a stack where every other original sheet was one-sided — the scanner still produces a page for the empty back, and you end up with blanks scattered evenly through the file. It's also useful cleanup after any bulk-scanning job before archiving or sharing. Once the blanks are gone, Compress is a natural next step, since the file is now smaller and often has more room to shrink further.
