What you need

Steps

  1. Put all the PDFs you want to work with in one folder so you can find them quickly. Give the files clear names.

  2. Open Copilot on your PC and type a plain request, such as asking it to merge the PDFs in a folder. Review what it suggests before you run anything.

  3. If Copilot cannot do the job, open Power Automate Desktop. It is free and already installed on most Windows PCs.

  4. In Power Automate Desktop, search the templates for a PDF merge or split template. Pick the one that matches your task.

  5. Set the template's input folder to the folder holding your PDFs, and set the output file name and location.

  6. Run the template and check the merged or split file opens correctly.

  7. For more control, create a custom flow. Add the PDF actions you need, such as merging files or extracting pages.

  8. Point each action at your source files, choose the page ranges for a split, and set where the new files should go.

  9. Save the flow, run it, and open the output files to confirm the pages are correct.

Tips and common mistakes

Keep a backup copy of your original PDFs before you merge or split them.

Test your flow on two small files first so a mistake does not affect a large document.

Check the page order in the output, since merged files follow the order you list them.

Copilot results can vary, so always open the finished file and check every page.

Questions

Do I need to install any software?

No. The guide uses Copilot and Power Automate Desktop, which are already available on most Windows PCs. You may need a Microsoft account to sign in.

Can I split only some pages from a PDF?

Yes. In a custom Power Automate Desktop flow you can set the page range to extract, so you get just the pages you need.

Is this really free?

Power Automate Desktop is free with Windows. Copilot access can depend on your Microsoft account, so check what your account includes.
