Questions people ask
Which installer do I need?
Most PCs need the standard (x64) installer. Snapdragon and other ARM laptops, such as recent Surface models, should use the ARM version. Both need Windows 10 or 11.
Is the app free?
Yes. The app is free to download and uses your PDFBetter plan. The free plan works in it, and a paid plan unlocks the same features in the app as on the web.
Is it different from the website?
It's the same PDFBetter, so new features reach the app as soon as they're on the web. The app adds opening PDFs from your computer, native menus and shortcuts, and a window of its own.
Does it work offline?
No. Your documents are stored in your account, so the app needs an internet connection, just like pdfbetter.com. When you're offline it shows a reconnect screen.
