How to use Remove Blank Pages
- Select the PDF.
- Adjust sensitivity if your scanner leaves specks on blank pages.
- Click “Remove blank pages”.
Detection
Each page is rendered small and the share of non-white pixels is measured. Pages below the threshold are removed; all other pages are copied losslessly. To choose pages yourself, use Delete PDF pages.
🔒 Your files never leave your device
bopdf processes your documents locally with JavaScript (pdf-lib and Mozilla pdf.js) inside your browser tab. Your PDF is never uploaded, stored or seen by us — you can even disconnect from the internet after the page loads and the tool keeps working. When you close the tab, everything is gone.
Frequently asked questions
Will pages with just a page number be removed?
Usually not at the default setting; raise sensitivity if you want them removed.
Are my files uploaded to a server?
No. Everything happens in your browser on your own device. Files are never sent over the internet, which makes bopdf suitable for confidential documents.
Is there a file size limit?
There is no fixed limit, but very large files (hundreds of MB) depend on your device memory. On phones, files up to about 100 MB usually work well.
