Your PDF is not our data.

Rendering, annotations, OCR, and export happen in your browser. Dusk PDF has no analytics SDK, advertising SDK, behavioral tracker, or document cloud in the current version.

QUESTIONS, ANSWERED

Know before you open a file.

Does Dusk PDF upload my documents?

No. The current version renders, edits, recognizes, and exports PDFs in your browser. Online PDFs are fetched only from the site you explicitly authorize.

Can I use it without an internet connection?

Yes. After the extension is installed, local documents and the bundled OCR capability work without an internet connection.

Will export overwrite my original PDF?

No. Dusk PDF creates a separate exported file so your source document remains unchanged.

Where can I get Dusk PDF?

The Chrome Web Store release is being prepared. This site will link to the official listing as soon as testing is complete.

COMING TO CHROME

Your next PDF deserves a calmer place.

Dusk PDF is currently in Chrome Web Store testing.
