Remove Blank Pages

Find and delete blank or nearly blank scanned pages automatically, with a manual override.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Remove Blank Pages works

PDF.js renders a small preview of each page and the share of non-white pixels is measured, ignoring a thin border. Pages under the limit (and without text) are marked. The rest are copied unchanged with pdf-lib.

Input: PDF. Output: PDF.

How to use Remove Blank Pages

1. Drop your PDF onto the Remove Blank Pages area, or click to choose it.
2. Wait a moment while page thumbnails render locally.
3. Choose the pages and options you need. Previews update as you go.
4. Press the main action button and download the finished PDF.

Tips

• Encrypted PDFs must be unlocked first with Unlock PDF.
• Large scanned PDFs are mostly images. Compress PDF shrinks them the most.
• Your original file is never modified; you always download a new copy.

Remove Blank Pages FAQ

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
