Why merge PDFs?

Combining PDFs keeps related documents together — chapters of a report, a stack of invoices, or scanned pages — in a single file that's easy to share, print and store. No more juggling attachments.

Is it private and safe?

Yes. Toolyard merges your PDFs inside your browser on your own device. Your files are never uploaded anywhere, so even confidential documents stay private.
