Merge PDF — Frequently Asked Questions

How do I merge PDF files online?

Add your PDF files to the box above, drag them into the order you want, and click Merge. Your combined PDF is ready to download in seconds.

Is it safe to merge PDF files with ZonePDF?

Yes. Files travel over an encrypted connection, are processed automatically, and are permanently deleted from our servers within a few hours.

Can I change the file order before merging?

Yes — drag and drop the uploaded files into any order. The merged PDF follows exactly the order you set.

How many PDF files can I combine at once?

You can combine a large batch of PDF files in a single merge. Without an account there is a cap on how many files the workspace holds at once — sign in to raise it. Need to join more? Merge in batches: a merged PDF can be merged again.

Can I merge only some pages from each PDF?

Yes. Switch to Pages view, remove the pages you don't want, and merge the rest. The grid shows every page of every file, so you build exactly the document you need.

Can I rotate or delete pages before merging?

Yes — in Pages view each page card can be rotated in quarter turns or removed, and you can drag pages into any order across files. Your original files stay untouched; the changes apply to the merged PDF.
