LockerPDF

PDF tools that never see your files

Merge, split, compress and convert PDFs entirely in your browser. Nothing is uploaded to a server — your files never leave your device.

No upload

Every tool runs client-side with WebAssembly and JavaScript. Your file is processed on your machine, not ours.

No account

No sign-up, no email, no watermark on your results. Open a tool and use it.

Works offline

LockerPDF is an installable app. Once loaded, most tools keep working without an internet connection.
