PDFgear (https://www.pdfgear.com) is a popular tool, but it has significant limitations. The main difference with FreeConversion is privacy: unlike PDFgear 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.
Absolutely! FreeConversion is perfect for professional documents. Since all processing happens locally in your browser, your confidential documents remain 100% private.
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.
The free and private alternative to PDFgear. No limits, no registration.
