About Remove Blank Pages
Scan a PDF and automatically delete blank pages — the empty backs of scanned duplex documents, spacer pages and accidental blanks. Adjustable sensitivity catches faint scanner noise while always keeping pages with real text. Runs entirely in your browser.
Where blank pages come from, and why they're worth removing
Blank pages rarely get added on purpose. They appear when a double-sided scanner dutifully captures the empty back of every single-sided sheet, when a document feeder drops in separator pages between files, or when someone leaves a spacer page in a template. Individually they seem harmless, but across a large batch they double your page count, waste paper and toner when the document is printed, pad the file size, and make the PDF tedious to scroll through. Cleaning them out before you archive, print or send a document keeps it tidy and professional.
This tool inspects the actual pixels on each page rather than trusting metadata. It renders every page and measures how much of it is covered in ink, and it also looks for a real text layer, so a page that only carries a faint scanner smudge can be told apart from one with genuine content. Pages that fall below the threshold you choose are flagged, and you get a clean document with just the real pages kept.
Getting the sensitivity right
The one judgement call in removing blank pages is deciding how empty is empty. A crisp digital export has truly white blanks that are easy to detect, but a real-world scan is noisy: dust on the glass, bleed-through from the other side of the paper, or a light pencil note can all leave a few stray marks. The strict, normal and aggressive settings move the threshold so you can match the tool to your scan. Strict protects anything with even faint marks and is the safe default when pages might contain a signature or stamp; aggressive is best for clean batches where you want every near-empty page gone.
Because the whole process runs in your browser with no upload, no account and no watermark, you can run a document at one sensitivity, glance at what was flagged, and try another setting if the result isn't quite right — all without your files ever leaving your device. If a page turns out to hold content you want after all, simply choose a stricter setting and run it again.
Questions
Everything runs in your browser. How we keep files private
How does the tool decide a page is blank?
It renders each page and measures how much ink — non-white pixels — actually covers it, and also checks whether any real text is present. Pages below the coverage threshold, with no text, are treated as blank.
Will it delete pages that have only faint content?
That's what the sensitivity control is for. On the strict setting a page with even a faint stamp, signature or handwritten mark is kept; on the aggressive setting near-empty pages are removed. Start strict if you're unsure.
Why do my scanned PDFs have blank pages in the first place?
Duplex (double-sided) scanners produce an empty back for every single-sided original, and document feeders often insert separator or spacer pages. That's where most unwanted blanks come from.
Is my document uploaded to clean it?
No. Every page is analysed locally in your browser, so even confidential scans stay on your device.
