Why switch from Nitro PDF to FreeConversion?

Nitro PDF (https://www.gonitro.com) is a popular tool, but it has significant limitations. The main difference with FreeConversion is privacy: unlike Nitro PDF 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.
