Stirling’s individual Free plan can cover many separate PDF tasks. Choose the deployment route and operation deliberately, then validate the output, especially when OCR, conversion or redaction changes how important information is represented.
Choose a local or self-hosted deployment when document location matters, then test the specific operation on a sample file. Review OCR and redaction output visually instead of assuming conversion is perfect. Check the automation-credit allowance before building a recurring batch-processing workflow around the Free plan.
