Why switch from Smallpdf to FreeConversion?

Smallpdf (smallpdf.com) is a popular tool, but it has significant limitations. The main difference with FreeConversion is privacy: unlike Smallpdf which sends your files to remote servers, FreeConversion processes everything locally in your browser using WebAssembly technology.

This means your sensitive documents (contracts, resumes, bank statements) never leave your computer. Additionally, FreeConversion is 100% free with no file limits, no registration, and no ads.

Frequently Asked Questions

Is there a file size limit?

FreeConversion handles large files directly in your browser. The limit depends mainly on your device's memory, but files up to 100MB are processed without issues.
