How we chose
PDF24 is strong, but its online tools upload files and it is Windows-only. We ranked the rest on price, whether the file leaves your machine, and forced accounts. PDFzen is the cross-OS, no-upload counter to PDF24's desktop model.
Honest note: if you want offline Windows, PDF24's desktop app is excellent — PDFzen is the browser alternative, not a replacement for it.
