If you are reading my posts on *Steemit,* you have certainly noticed that I have a lot of screenshots in my tutorials or a lot of photos for my travel posts.

Resizing images is one of those things that can take you a lot of time when you have *20* to do. I have been resizing all my images to *1,000 pixels* for *Steemit* using *Automator on Mac* and it is great when you have more than *20* to resize frequently.

You may want to read the post here: *[How to Resize Images Automatically with Automator on Mac!](https://steemit.com/tutorial/@gmichelbkk/how-to-resize-images-automatically-with-automator-on-mac)*

Today, I am showing you a simpler method that everyone can start to use now.

## How to Easily Batch Resize your Images on a Mac!

First, I prepared a folder with *5 screenshots* that I am going to resize.

Screenshots always have different sizes like you see below where the width is *1,310, 1,305* or *1,309.* This is too large and I want them to be all the same width.

The first thing is to select them all in the window using the keyboard shortcut *"Cmd + A."*

Then, you click right and select *"Open With"* and *"Preview."*

This will open the preview window with all the images in it.

You can use the keyboard shortcut *"Cmd + A"* or the menu to select them all: *"Edit"* and 
*"Select All."*

Then, go to *"Tools"* and *"Adjust Size."*

This will open this panel where you can select a *"Custom"* size if you wish.

Instead, I am going to select a default size: *"1024 x 768"*

Note that *"1280 x 720"* and *"1920 x 1080"* are very useful sizes for thumbnails.

So here I have the width: *"1024"*

The height will be different for each image, but what's important for my blog is to have the same width.

Note that *"Scale proportionally"* and *"Resample image"* are checked.

The images were *4.8 MB* and they are now *3.2 MB.* This is not an optimization tool, but it's still good to see a reduced file size.

Click *"OK"* when you are ready to resize.

The images are resized now.

Save and close *"Preview."* 

You can verify that the images were indeed properly resized.

This one has the new width of *"1024"* like all the others.

I bulk-resized all 11 images in this tutorial using this method without problems.

I hope that this is useful for you if you are a *Mac* user.
