How to remove duplicate pages in a PDF online for free

  1. Open the Delete Pages page on our site.

  2. Drag and drop your PDF document into the toolbox.

  3. Hover over the duplicate page(s) and click the trash bin icon to delete them.

  4. Click ‘Apply Changes’ and download your saved file.


Remove duplicate pages from your PDF in one go

Zoom or rotate before deletion


While you are inside 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, which is shown whenever you hover over the page thumbnails. Zooming makes it easy for tasks such as searching for duplicate content within a single PDF.

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 commence the removal process. Both of these tools are readily available via our homepage.

Free to use, on any device


Smallpdf is the most visited PDF software on the internet, with over 25 monthly users. We strive to responsibly relieve you of any PDF-related nuisance, including the need to remove, modify, or add PDF pages. Our online PDF tools are free for limited use for anyone. And if you are a frequent user, you can sign up for a ‘Pro Account’, which enables unlimited usage, along with many other premium features.

Our team believes in affordable access to PDF software for everybody, which is why our site will remain free to use. Even as a daily user, you can get a subscription sans the expensive price tag, i.e., for an Adobe Acrobat Pro account. We will also increase the file size to 5GB, which will enable you to remove duplicate pages in PDF online easily, for any digital document.

And lastly, do check out many of our other online tools. If you need to delete pages from a digital document of another format, remember that you can always first convert it to PDF format, remove the pages, and then save it back to its original form - whatever you need.

Can I delete duplicate PDF pages offline?


For sure - by using the Smallpdf Desktop app. Unlike the online version; this one requires a Pro account to use, albeit a 14-day trial is always up for grab via our pricing page. To achieve this feat offline, follow the instructions below:

  1. Open the PDF with our desktop app.

  2. On the right-hand panel, choose ‘Delete, Rotate Pages’.

  3. Hover over each file, and click the trash icon.

  4. Click the floppy disk icon at the top of the pages to save the changes.

  5. To batch delete, highlight multiple pages, and click the trash bin at the top.

Other than batch processing, you can also rotate, undo, or even insert a blank page into the PDF file. As always, drag the pages around to re-arrange your files. We hope you enjoy editing your PDFs as much as we’ve enjoyed building both platforms.
