Privacy: the most important difference
iLovePDF and Smallpdf both upload your files to their servers. They delete files after a few hours, but your documents are transmitted over the internet and processed on external infrastructure. For sensitive documents — payslips, contracts, medical records, passport scans — this is a real risk.
RightPDFKit processes everything in your browser using WebAssembly. Your files never leave your device. This is a fundamental architectural difference, not just a privacy policy claim.
Speed
Because files don't need to upload and download, RightPDFKit is typically faster for operations like merge, split and compress — especially on larger files or slower internet connections. There's no waiting for a server to process and return your file.

- ✅ Good server-side PDF conversion (Word, Excel, PowerPoint)
- ✅ Long-established, reliable service

Smallpdf — pros and cons

RightPDFKit — pros and cons

- ✅ Works offline after first load

- ⚠ Word-to-PDF conversion is limited (browser WebAssembly constraint)
