How to merge PDF files
- Select your PDFs, or drop them onto the box above. You can add more at any time.
- Put the files in order by dragging them, or with the arrow buttons on a phone.
- Choose Merge PDF, then download the combined file.
Your files stay on your device
Your browser reads each PDF and copies its pages into the combined file in the order you set, all on your own computer or phone. If you’re putting a contract together with its signed schedules, none of it passes through Oppermind, and the page keeps no copy of your files after you close the tab. Analytics on this page run only if you allow them, as our privacy policy explains.
Questions
Is merging PDFs here free?
Yes. You don’t sign up or enter a card, and the merged PDF comes out without a watermark.
Are my files uploaded?
No. The PDFs are read and combined by your browser on your own device. Oppermind’s servers never receive them.
Is there a file size limit?
There’s no fixed limit. Because the work happens on your device, very large files depend on its memory and can be slow on an older phone.
Can I merge a password-protected PDF?
Not here. Open it with the password, save a copy without one, then add that copy.
What carries over into the merged file?
The pages, with their text, images, comments and links to websites. Bookmarks don’t carry over, links that jump to another page may stop working, and form fields may stop being fillable, so fill in any forms before you merge.
