Frequently asked questions

Can I control the order of PDFs before merging?

Yes. Drag and drop the files in the list to set the order. Pages are merged exactly as shown.

Is there a limit on how many PDFs I can merge?

No hard limit. You can merge as many files as your browser's memory allows.

Will bookmarks and hyperlinks be preserved?

Internal links within each individual PDF are preserved. Cross-document bookmarks are not combined.

Can I merge password-protected PDFs?

You'll need to unlock them first using Smash's Unlock PDF tool, then merge.

Is this safe for confidential documents?

Yes — all processing happens in your browser. No file is ever uploaded to a server.
