Frequently Asked Questions
Are my documents sent to your servers?
No. PDF Toolkit Pro executes 100% on your device using client-side JavaScript. Your confidential files never touch an external server or database.
Is there a limit on file size or number of files?
Because processing happens on your local device, there are no artificial subscription paywalls or file quantity limits. It can handle hundreds of pages as long as your computer has standard free memory.
Are hyperlinks and vector resolutions preserved?
Yes. The underlying vector paths, typography metrics, and structural page streams are retained in accordance with the ISO 32000-1 specification.
