FAQs
Is this PDF merger really free?
Yes — completely free with no signup, ads or watermarks. Use it as many times as you want.
Are my PDFs uploaded anywhere?
No. Everything runs inside your browser using pdf-lib. Your files never touch our servers.
Is there a file-size limit?
Limited only by your device's RAM. We've tested 100MB+ merges on a regular laptop.
Can I reorder the PDFs before merging?
Yes — drag the items in the list to reorder, or use the X button to remove a file.
Does it work on mobile?
Yes, on Chrome, Safari and Firefox on iOS & Android.
