Automatically Remove Blank Pages
📌 How it works:
1️⃣ Open a PDF to measure each page's non-white pixel ratio and identify potentially blank pages.
2️⃣ Only thumbnails of potentially blank pages are shown below for your review.
3️⃣ Use the slider to adjust the detection threshold (a lower threshold is stricter).
4️⃣ After reviewing, click "Delete Selected Blank Pages and Save" to create a PDF without those pages.
💡 Bookmarks are kept, but their page numbers may be inaccurate because destinations are not remapped.

Frequently asked questions
What does a lower detection threshold do?
It makes blank-page detection stricter: a page must contain fewer non-white pixels to be flagged as potentially blank.
Are bookmark destinations updated after blank pages are removed?
Bookmarks are kept, but their page destinations are not remapped. They may become inaccurate after page removal, so check them in the output.
