The Verdict
PDF24 is an excellent free tool with a broad feature set and a useful Windows desktop app. It's a strong choice for Windows users who don't mind server-side processing.

Both are genuinely free, so the deciding factor is usually privacy requirements.
SublimePDF's client-side architecture is built on WebAssembly and processes files in the PDF open standard (ISO 32000), ensuring compatibility and privacy across all platforms.
