Why both formats exist
JPG was the right answer at one point in computing history. PDF is what's right today. Both still exist because the world is full of files in JPG that no one is going to re-create, and tooling like JPG to PDF lets us bridge that gap without forcing a wholesale migration.
Use the tool
Browser-only. Nothing is sent to a server.
Frequently asked questions

Does JPG to PDF upload my JPG file?
No. JPG to PDF converts in your browser using WebAssembly. The file stays on your device.
