Pro Tips: Find and Remove Duplicate PDF Pages Faster
While using the tool to delete duplicate pages in your PDF, you can also rotate or zoom in to check the content of each individual page if needed.
These options are listed right next to the remove pages icon, shown whenever you hover over the page thumbnails. Zooming makes it easy to look for duplicate content within a single PDF to be sure you’re deleting the right pages.
If you need to find duplicate pages from multiple PDF files, you can always merge them into one PDF using our Merge tool. Then, head over to the Delete Pages tool to find and remove the duplicates.
Troubleshooting Common Issues When Removing Duplicate Pages
If something isn’t working as expected, these quick checks usually help.
I Can’t Select or Delete a Page
Wait for the PDF to load fully in the preview. If the thumbnails look blurry or unfinished, let the tool finish processing. If your connection is slow, refresh the page and upload the file again.
Ctrl (Windows) or Cmd (Mac) Won’t Select Multiple Pages
The browser window may not be active. Click once inside the thumbnail area, then try again. If shortcuts still fail, click each page individually and use the trash icon.
My PDF Won’t Load or Gets Stuck While Uploading
Large or scanned PDFs may take longer to load. Open the file locally to make sure it’s not damaged. If it still won’t upload, save it as a new PDF on your device and try again.
I Can’t Delete Pages From a Protected PDF
Locked files require the password before editing. Unlock the PDF first with the Unlock PDF tool, then return to Delete Pages to remove pages.
Duplicate Pages Won’t Delete Because They’re Part of an Image
Scanned PDFs sometimes contain long image strips instead of separate text layers. Zoom in to check whether the page is a repeated scan. If needed, split the file first, then delete the unwanted section.

FAQs About Deleting Pages from a PDF
How do I delete multiple pages at once?
Hold Ctrl (Windows) or Cmd (Mac) while clicking on the page thumbnails you want to remove, then click the trashcan icon to delete them all at once.
Can I undo page deletion after saving?
Once you’ve downloaded your edited PDF, the changes are permanent. But you can always re-upload your original file and start over if needed.
Will deleting pages reduce my PDF file size?
Yes. Removing pages will reduce your file size proportionally, making it easier to share and store your document. If you need to reduce file size even more, try our free Compress PDF tool.
What’s the difference between deleting and extracting pages?
Deleting removes pages permanently, while extracting creates a new PDF with only the selected pages, keeping your original file intact.
Can I delete pages from a password-protected PDF?
Yes, but you’ll need to unlock the PDF first by entering the password. Then you can delete pages as normal.
How many pages can I delete at once with Smallpdf?
There’s no limit to how many pages you can delete in a single session. Remove as few or as many as you need.
How do I spot duplicate pages in a PDF?
Most duplicates show up as pages that look identical or nearly identical when you flip through the thumbnails. Use the zoom tool to check details or rotate pages for a clearer comparison. If your duplicates come from a merge, scroll through the preview to confirm each section appears only once.
Why do duplicate pages appear when scanning documents?
Scanners often repeat pages if the feeder mis-detects a sheet, if a page sticks, or when you scan in batches and later combine the files. That’s why duplicates are common in workplace scans, school notes, and admin paperwork.
Can Smallpdf remove duplicate pages automatically?
Not automatically. But you can merge your files first, open the combined PDF in the Delete Pages tool, and manually remove any repeated pages using the thumbnail preview and zoom controls for accuracy.
