10 Tips To Make The Most Of Preview On Mac
Preview is one of the ѕtoсk apps that come preloadеd on your Mac machine. For most users, it’s just an image νiewer that allows them to open and view various types of іmages avаilable on their Macs.
However, that’s not the case. The Preview app on Mac is capable of doing more than just letting you view your images. There are many features that this app has for you only if you’re willing to uncover and use them for your tasks.
Some of these little talked about features of Preview include the ability to lock your PDF files, add a signature to your files, and even edit your images. Once you’ve learned to use these features, you’ll no longer need to use any third-party apps that you might have installed on your machine.
Modify Multiple Files At Once
One of the most time-consuming tasks you could ever come across is probably having to make the same change to many files on your Mac. Opening each file and making the change is simply a waste of time, especially when you have an app like Preview available on your Mac.
With Preview on your Mac, you can make changes like modifying the image resolution of multiple files at once. There are several other uses of it as well.
- Select the images you want to change the resolution of, right-click on any one of them, select Open With, choose Preview, and Preview will open.
- Click on the Tools menu at the top and select Adjust Size.
- Enter in a new size for your multiple images and hit OK.
All of your selected images will now have your new resolution.
Add a Signature To Your Files
You no longer need to sign a white paper, scan it, crop your signature, and then place the signature on your digital document. With Preview, you can directly sign any of your files on your Mac.
- Launch your PDF document in the Preview app.
- Click on the Show Markup Toolbar icon at the top.
- Find and click on the signature icon in the toolbar. If you don’t already have a signature, click on Create Signature to create one.
You can then place your signature anywhere you want in your document.
Convert Files From One Format To Another
Tasks like file conversion often require you to find and install a third-party app on your Mac. However, if your file is one of Preview’s supported formats, you can have it converted to another format using Preview itself.
- Open your file in the Preview app on your Mac.
- Click on the File menu at the top and select the option that says Export.
- On the following screen, you’ll see a dropdown menu saying Format. That’s where you can choose the new format for your file. Choose from any of the available options and click on Save.
Your file will be saved in your chosen format on your Mac.

- Click on the Instant Alpha tool in the toolbar.
