PDFs opening in Chrome instead of Acrobat?
The System PDF Hijack Repair Toolkit puts your PDF app back in charge. A 90-second triage tells you which fix you need, then illustrated steps walk you through it. Most fixes are one settings change, and nothing on your computer gets deleted.

Your PDFs didn't break. Your browser took them over.
- Every PDF I download now says "Chrome HTML Document."
- I double-click a PDF and it opens in Edge, not Acrobat.
- I changed the default app and it reset itself a week later.
- Printing from the browser comes out wrong, and the office printer is next to my desk.
A browser update quietly made itself the default PDF app. The file is still a normal PDF. You just need to hand it back, the right way for your system, so it stays fixed.
A 43-page illustrated guide and 12 printable cards.

Before you buy
Why are my PDFs saving as "Chrome HTML Document"?
Windows has made Chrome (or Edge) the default app for .pdf files, usually after a browser update or reinstall. The file is still a normal PDF; only the app that opens it changed. The guide shows how to hand .pdf back to Acrobat or the reader you choose.
Will a fix delete anything?
No. Most fixes are one settings change. Nothing on your computer is deleted, and every step says how to undo it.
Which systems does it cover?
Windows 11 and Windows 10, and macOS 11 Big Sur through macOS 26 Tahoe, with Chrome, Edge and Firefox.
Do I need to be technical?
No. It starts with a 90-second triage of three questions that points you to the right fix, and every fix is illustrated step by step.
How do I get it?
It's an instant download: two PDFs, the 43-page guide and a 13-page deck of 12 reference cards. Nothing ships.
