Why SmallPDF Users Switch to PDF Filler
- SmallPDF's 2-task/hour limit. SmallPDF restricts free users to 2 free tasks per hour before requiring a Pro subscription at $9/month. PDF Filler has no task limits at all.
- SmallPDF requires account creation. After a few uses, SmallPDF asks you to sign up to continue. PDF Filler never asks for an account.
- SmallPDF uploads your files. Every PDF you process on SmallPDF is sent to their servers in Switzerland. PDF Filler runs entirely in your browser — your files never leave your device.
- SmallPDF's free tier is shrinking. Over the years SmallPDF has removed features from the free tier. PDF Filler is committed to keeping every feature free.
