Sejda's free tier blocks you after 3 tasks per hour. When you're batch-processing documents or working against a deadline, that limit is a real problem. FastPrivatePDF has no task limits.
Sejda uploads your files to their servers for processing. For contracts, payslips, medical records, or any confidential document, that's a significant concern. FastPrivatePDF never uploads anything.
