Where Smallpdf Wins
Smallpdf offers a much broader tool set — PDF compression, OCR, e-signatures, Word conversion, page editing, and more. If you regularly need these advanced features, Smallpdf's paid plan ($12/month) is reasonable for power users.
Smallpdf's UI is also very polished and has mobile apps for iOS and Android.
Where ConvertToPDF.online Wins
Privacy: This is the biggest differentiator. Smallpdf uploads your files to Amazon S3 or similar cloud storage, retains them for up to 1 hour, and processes them on their servers. ConvertToPDF.online processes everything in your browser — files never leave your device.
Speed: ConvertToPDF.online converts instantly using your own CPU. Smallpdf's free tier queues requests on shared servers — during peak hours, simple conversions can take 15–30 seconds.
No limits: Smallpdf's free tier limits you to 2 tasks per hour. If you hit the limit, you either wait or pay. ConvertToPDF.online has zero limits — convert 100 files in a row if you need to.
Free, forever: ConvertToPDF.online is supported by display advertising. There is no paid tier, no premium features, and no time-limited trials.
Which Should You Use?
For everyday image-to-PDF and PDF-to-image conversions with privacy in mind, ConvertToPDF.online is the better choice — faster, free, and zero-upload.
For advanced PDF editing, OCR, compression, and e-signatures on a regular basis, Smallpdf's paid plan is worth considering.
