Great value for a one-time purchase. No Adobe Acrobat dependency to install or maintain.
Dropped in a folder of Adobe PDF (*.pdf) → Adobe PDF (*.pdf) files and it was done — refreshingly simple. Clean interface with practically no learning curve.
Free online tools choke on large files and upload everything to the cloud. PDF Encrypter just works locally. Fast enough for daily, high-volume workloads.
It handled our password-protected PDFs without any drama. Free updates are included with the license.
