Make it yours

Make CrescentPDF your default PDF app

How to do it

Once it's your default, every PDF you double-click opens in CrescentPDF.

When you install, leave Open PDF files with CrescentPDF ticked. That's all it takes.
To change it later, right-click any PDF in File Explorer and choose Open with, then Choose another app.
Pick CrescentPDF and choose to always use it for .pdf files.
Double-click any PDF. It now opens in CrescentPDF.

Good to know

You can also set it in Windows Settings: open Apps, then Default apps, and look up .pdf.
Opening from inside the app works too: press Ctrl+O, or drag a PDF onto the window.

Try it in CrescentPDF.
