FAQ
Should I merge PDFs before or after compressing them?
For many workflows, merge first to verify page order, then compress the final PDF if the combined file is too large.
Can merged PDFs have different page sizes?
Yes, but mixed sizes can look inconsistent. Review the final document before sending it to clients or uploading it to portals.
