Frequently asked questions
Are my PDF files uploaded?
No. Your files are merged inside your browser and never leave your device.
Can I change the order of the files?
Yes. Drag files up or down the list, or use the arrow buttons, before you merge.
Will merging reduce the quality?
No. Pages are copied unchanged, so text stays selectable and images keep their original resolution.
Is there a file size limit?
You can merge up to 50 files of up to 200 MB each. In practice the limit is your device's memory, so very large documents work best on a computer.
Can I merge password-protected PDFs?
Remove the password with Unlock PDF first (you'll need to know it), then merge the unlocked file.
