How To Set Preview As Default On Mac

Have you ever opened an image or PDF on your Mac and thought, "Why is this clunky app popping up when I know there's something better?" You're not alone. Let's fix that once and for all by making Preview your go-to app for all things image and document viewing.

Preview is the elegant, built-in tool that Apple crafted just for you. It's fast, reliable, and it looks gorgeous while doing its job. Why settle for anything less?

Why Preview Deserves the Top Spot

First off, Preview does more than just display files—it lets you annotate, edit, sign, and even rearrange pages with ease. Have you ever signed a PDF without printing it? Preview makes that feel like magic.

It also handles images beautifully, offering simple crop, rotate, and color adjust tools. No need to fire up Photoshop for quick edits when Preview has you covered.

Best of all, Preview comes free with every Mac. That means you've already been paying for it with your purchase—it's time to take full advantage!

Setting Preview as Default for Images

Let's start with images, since that's where most people notice the default issue. Right-click (or control-click) on any image file, like a PNG or JPEG.

Select "Get Info" from the menu that appears. Look for the "Open with:" section near the top of the Info window.

A confirmation dialog will pop up—go ahead and hit "Continue." This simple step sets Preview as the default for every image file with that extension. Easy, right?

Setting Preview as Default for PDFs

The process for PDFs is almost identical. Find a PDF, right-click it, and select "Get Info."

Under "Open with:", pick Preview from the dropdown menu, then click "Change All." Confirm the change, and PDFs will now always launch in Preview.

Think of this moment as your personal digital upgrade. Every time you open a file, you'll experience a smooth, seamless flow instead of an annoying surprise.

Handling Other File Types

Don't stop there! You can apply this same trick to HEIC, TIFF, and many other formats Preview supports. Just follow the Get Info → Open with → Change All dance each time.

If you ever want to revert to the original default, the process works in reverse. Simply choose the other app in the dropdown and hit "Change All" again.

It's like having a remote control for your Mac's everyday behavior. And honestly, that kind of control feels incredibly satisfying.
