Questions
Quick answers about merging PDFs with PurePDF.
Is there a limit on file size or quantity?
No. Add as many PDFs as you need. Processing happens locally, so we never throttle usage.
Can I merge password-protected PDFs?
Yes, as long as you know the password. Unlock locally, then add the file to the queue.
Will merging change fonts or layouts?
Every page is copied exactly as rendered in the original file, so fonts, images, and spacing stay intact.
How do I share the merged file?
Download instantly or send it into PurePDF Share to generate a private link for teammates.
Do you store my files on your servers?
Files are uploaded only to perform the merge and are deleted immediately after processing completes.
