Frequently Asked Questions: Sejda PDF vs PDFDock

Q.Why does Sejda limit users to 3 tasks per hour?▼

Sejda processes files on expensive backend cloud servers, so they enforce strict 3-task-per-hour limits to push users into paid plans. PDFDock executes in your browser, so our server costs are nearly zero and we can offer unlimited free usage.

Q.Can I process PDFs with more than 200 pages?▼

Yes. PDFDock has no 200-page cap. You can merge, split, rotate, and compress documents containing hundreds of pages effortlessly.
