Installing on Windows — about the SmartScreen notice

Windows may show a blue “Windows protected your PC” window. That’s expected for new, independent software — it means the file is unfamiliar to Microsoft, not that anything harmful was found. Click More info, then Run anyway. You can also use the browser version, which installs nothing.

Good to Know

Questions

Is it really free?

Yes. Every feature is free for personal and commercial use. There’s no trial, no paywall, and no “Pro” upgrade.

Do I need an account?

No account to create — just the shared access password (ask your team). That unlocks the app and downloads; everything then runs on your own device.

Do my files get uploaded anywhere?

Never. Signing in only unlocks access — it doesn’t change how the editor works. All editing happens on your own device, in the app or your browser tab, with nothing uploaded.

What’s the difference between the browser version and the download?

They’re the same editor. The browser version needs nothing installed and works on any operating system. The download works offline forever, handles very large files more comfortably, and integrates with your file manager.

Which platforms are supported?

The browser version runs anywhere with a modern browser. Desktop downloads are available for Windows 10/11, macOS (Apple Silicon and Intel), and 64-bit Linux.

Windows says “Windows protected your PC” — is something wrong?

No. SmartScreen shows that notice for installers it doesn’t yet recognize, and this is a new, independent app. Click More info, then Run anyway — or just use the browser version, which installs nothing. You can also verify the file on VirusTotal or install with your internet disconnected, since the app works entirely offline.

Will I get a warning on a Mac?

No. The Mac download is signed with our Apple Developer ID and notarized by Apple, so it installs and opens with no warnings.

Your documents. Your device.

Open a PDF and start editing — in your browser or on your desktop. Free, private, and yours.
