Quick answer
Add your PDFs, put them in order with the arrows, and merge. The files are combined in your browser.
Step by step
- Open Merge PDF.
- Drag in your PDF files. Click again to add more.
- Use the up and down arrows to set the order. The order of the list is the order of the final file.
- Click "Merge PDFs" and download the combined file.
Tips
- Rename files 01, 02, 03 before you add them so the order is obvious.
- Check page sizes and orientation. Mixing A4 and Letter looks untidy in the final file.
- Scroll through the result once to catch a missing or upside-down page.
- If the merged file is too large to send, run it through Compress PDF.
How to check that nothing is uploaded
Open your browser developer tools (F12), go to the Network tab and run the merge. You will not see your files being sent anywhere, because the pages are combined on your device.
Good to know
The merge orders whole files. To reorder individual pages, pull them out with Split PDF and merge them in the order you want. Your original files are not changed.
