FAQ

Should I use an online PDF converter for client files?

Only if your organization approves the service and its data-processing terms. Otherwise prefer approved desktop or managed cloud tools.

Is a PDF reader the same as a PDF editor?

No. Many readers are free for viewing and annotation, while editing, OCR, and e-signing may require paid plans.
