Free · No sign-upFrequently asked questions
Are my PDFs uploaded to a server?
No. Merging happens entirely in your browser on your own device. Your files never leave your computer or phone.
How many PDFs can I merge at once?
Up to 50 files and about 300 MB in total per merge, with no page limit. Need more? Merge in batches, then merge the results.
Can I merge password-protected PDFs?
Yes. Enter each file's password when asked. The merged PDF opens without a password.
How do I change the order of the files?
Drag a file up or down in the list, or use the arrow buttons next to it. The number on the left shows its position in the merged PDF.
Will the quality change after merging?
No. Pages are copied as they are — text stays selectable and images keep their original quality.
Is there a watermark or sign-up?
No watermark, no sign-up and no daily limit. It's completely free.
