Bulk resizer for Mac: Edit, watermark, resize

PhotoBulk is a life-saver for when you need to change the size of multiple images. Drop them into the app and resize in a sec.

How to resize images on Mac

Let’s start with the basics. Macs actually have a built-in image editing software that can resize images on your Mac. If you go to Finder > Applications and scroll through the apps, you’ll find Preview, an image viewing and editing app that comes with your Mac. And yes, Preview can resize your image.

Here’s how to do it:

1. Open an image in Preview (simply double-click on the file to open it and Preview is the default option in most cases).
2. Find Markup icon in the top menu bar of the Preview window (for narrow images, the icon often hides behind the >> .
3. In the Markup mode, click Adjust Size icon:

4. In the pop-up window, set your desired image dimensions and click OK:

Note that by default, Preview saves all edits in the existing file. To keep both your original image and the resized (or otherwise edited) one, go to File > Export… and save your changes as a new file.

Resize multiple images at once

But you don’t have to go resizing your photo collection on Mac one by one. You can actually batch resize both with Preview or apps like batch editing and watermarking tool PhotoBulk.

Let’s start with Preview. Here’s a step-by-step for batch resize there:

1. Select all images you want to resize in a Finder folder and right-click on them.
2. Select Open With… and click on Preview.
3. As you get your images open in Preview, you’ll see one selected image in the center and the rest as thumbnails on the side. Select all thumbnails with Command + A.
4. Click Tools in the Preview menu bar at the top and pick Adjust Size… option.
5. Set your resize settings in the pop-up window and click OK:

Note that all images will be saved on top of your existing files, so if you want to only create resized copies, make sure you create copies first.

Now, let’s test multi image resize in PhotoBulk.

In the app, all you have to do is drag and drop your batch onto the window and then select your editing options.

In addition to resize, you can choose to optimize your images, delete or keep only part of the image metadata (can be useful if your phone records image location and you want to share an image online, as well as multiple other privacy uses), change image format, batch-rename, and watermark the image. Now, in our sample, we chose the script setting for watermarking, but you actually have a choice to set this up in other watermark formats, including just adding a date stamp, an image (like a logo), or a single watermark anywhere on your pic.

Crop an image in Preview

And since we’ve already got one foot in image editing, let’s also see how to crop an image on your Mac. After all, one answer to how to reduce image file size on Mac is simply cropping out the extra space in your pic — a space that in many cases can be very well done without.

Open your image in Preview and follow these steps to crop your photo or other visual:

1. Find and click the Markup icon in the window Menu bar (may be hidden under the >> icon in narrow images).
2. Select the area you want to keep (click, drag, and release to make the selection).
3. Click the Crop to Selection icon that appears when you’ve made the selection:

4. That’s it, your image gets cropped to your selected area!

Note that the edited photo gets saved instead of your original, so crop only the version you are ready to part with.

Bonus tip: Convert to any format & enhance your photo

Now that you know how to resize an image in Preview, as well as resize, watermark, and bulk edit images in PhotoBulk, let’s investigate how to convert your visuals to various formats and enhance them with filters and cool AI tools.

First off, Permute is a universal media converter that can help you convert images, video, and audio to a number of formats. Just drag and drop your images to the Permute window and select the format you want to convert them to — PDF, JPEG, PNG, HEIF, etc.

If the file format you want isn’t in the drop down menu of the converter, you can actually click Add Preset… > Add New Preset…, select Image, and add more formats, including BMP, GIF, TIFF.

And by the way, since we are talking about how to resize an image on Mac, Permute knows how to do that too — simply click the wheel icon in the top right corner and check the Resize option:

Luminar is another app you might find handy when working with photos. Just like Permute, we refrained from including this solution in our guide on how to resize a photo on Mac as the key function of this app is AI-enhanced image editing that can help turn your takes into something breathtaking. That said, since you are looking for a tool to reduce photo size on Mac, we’ll start with this feature of the app.

The resize works through export once you are done editing your shot. Find File > Export… in the app’s Menu bar at the very top of your Mac’s screen (as opposed to the top of the app window). And set your Resize settings in the respective field that pops up:

Luminar resize tool lets you set the pixel length of each side of the pic individually, as well as by long or short edge. Make the changes you want and click Save to export your edited visual.

Speaking of editing, we just have to talk about the best part about this photo editor — Luminar offers sets of AI-enhanced looks that can take your photos from good to breathtaking.

Thing is, you must realize that downsizing your image can lead to a poorer quality result. So how can you resize and keep the quality? Well, all you have to do is figure out your end use — what exact size you need for your project or use purposes?

And finally, along with the image size settings, you will often get image quality slider which is vital when adjusting the quality of your final image:

The same slider is available in Luminar during image export. In PhotoBulk, you can find it under Format.
