Frequently asked questions
Is it safe to merge PDFs with Inopax?
Yes. Merging happens entirely inside your browser, so your PDFs are never uploaded to a server and nobody else can see them.
How many PDF files can I merge?
You can merge up to 50 files at once on the free plan, with no daily limit and files up to 250 MB each.
Will the quality of my PDFs change?
No. Pages are copied exactly as they are — text stays selectable and images keep their original quality.
Can I merge password-protected PDFs?
Remove the password first with the Unlock PDF tool, then merge the unlocked files.
