PDF-Atlas

A PDF toolkit that works entirely on your device.

Edit, convert, sign, and merge documents with a quiet, fast interface built for people who care about their files staying their own.

Architecture

Privacy is not a setting. It is the architecture.

Conventional PDF tools upload your documents to remote servers and trust you to read the privacy policy. We engineered a WebAssembly pipeline that runs the entire transformation graph locally — so there is nothing to upload and nothing to leak.

  • Local processing

    Every transformation runs inside your browser sandbox. No relay servers, no background uploads, no telemetry on file contents.

  • Native speed

    Tools share a WebAssembly core tuned for streaming throughput. Hundred-page documents stay responsive on modest hardware.

  • Offline first

    Install the PWA or download the desktop build. Works in airplane mode, on flaky networks, or air-gapped machines.

Get started

Drop a file. Keep your privacy.

No account. No upload. Open a tool, work, close the tab — there is nothing left behind.
