How to Remove Blank Pages from a PDF — Step by Step

Blank pages often appear in scanned documents, printed forms, and exported reports. Doclair automatically detects and removes blank pages from your PDF in your browser with no upload required.

Upload your PDF. Drop your file into the scanner — detection starts automatically.
Doclair scans each page for content. Each page is rendered and its pixels sampled to determine if it is blank.
Review the detected blank pages. Uncheck any page you want to keep before removing.
Click Remove Blank Pages and download the cleaned PDF. The original file is never modified.

How does Doclair detect blank pages?

Doclair renders each page and checks pixel content — a page is considered blank if more than 98% of pixels are white or near-white. Lightly watermarked pages or pages with faint content may or may not be detected as blank depending on the threshold.

Frequently Asked Questions

Each page is rendered at a low resolution (20% scale) and its pixels are sampled. A page is considered blank if fewer than 5 sampled pixels contain non-white colour. This catches truly blank pages as well as pages with very light artefacts.

The detector uses a strict threshold — only pages that are almost entirely white are flagged. You can review the list of detected blank pages before removing anything, and uncheck any page you want to keep.

Yes. After scanning, you see a checklist of all detected blank pages with their page numbers. Each one is checked by default — uncheck any you want to keep before clicking Remove.

Yes — scanned PDFs are images, so the pixel-sampling approach works well. However, a scanned page with faint background texture may not be detected as blank even if it appears nearly white.

No. Everything runs in your browser — blank page detection uses pdfjs-dist (WebAssembly-powered) and page removal uses @cantoo/pdf-lib, both executed locally. Your file never leaves your device.
