Loading Delete PDF Pages...
⚙️ How It Works
Upload a PDF file and enter the page numbers or ranges you want to remove (for example: 2, 5-7). The preview highlights the pages that will be deleted so you can confirm your selection. When you click 'Remove', a new PDF is generated instantly with those pages excluded and downloaded to your device.
❓ Frequently Asked Questions
How do I delete pages from a PDF?
Upload your PDF, enter the page numbers you want to remove (for example: 2,4,7-10), preview the selection, and download the new PDF.
Are my sensitive PDFs uploaded anywhere?
No. All processing happens locally in your browser using JavaScript. Your PDF never leaves your device and is not uploaded to any server.
Can I delete multiple pages at once?
Yes. Enter multiple page numbers separated by commas, or use ranges like 5-10 to remove several pages at once.
Can I preview which pages will be deleted?
Yes. The page preview shows which pages are marked for deletion so you can visually confirm your selection before processing the PDF.
Does this work offline?
Yes. Once the page loads, the tool can run entirely offline because all PDF processing happens directly in your browser.
Will the original PDF be modified?
No. The original file remains unchanged. The tool generates a new PDF with the selected pages removed.
Is there a file size limit?
There is no strict server limit since processing happens locally, but very large PDFs may be limited by your browser's available memory.
Which browsers are supported?
The tool works in all modern browsers including Chrome, Firefox, Edge, and Safari. Older browsers that do not support modern JavaScript features may not work properly.
Can I use this tool on mobile devices?
Yes. The tool works on modern mobile browsers on Android and iOS, though very large PDFs may perform better on desktop devices.
Can I edit password-protected PDFs?
Password-protected PDFs must be unlocked before they can be processed. Remove the password protection first, then upload the file again.
How long does it take to remove pages?
Processing usually takes only a few seconds depending on the size of the PDF and the number of pages being removed.
Does the Delete PDF Pages work offline?
Yes, the Delete PDF Pages is fully functional offline. Because this tool runs entirely in your browser, no data is ever uploaded to external servers. Once the page is loaded, you can seamlessly continue using it without an active internet connection. You can also install Knicknaks as a Progressive Web App (PWA) for native-like offline access.
