How to Resize an Image in Mailchimp (Automatically)

In December 2018 Mailchimp changed to a new image editor also called the photo editor). In my Mailchimp classes I get many people asking how to use the image editor to resize images.

The video below gives instructions on how to resize images automatically in the Mailchimp image editor.

Note: I have separate instructions available about how to crop images in Mailchimp.

Hi. I’m Gary from organicweb.com.au. I’m a Mailchimp partner and I deliver Mailchimp training and provide these videos to try and help people use Mailchimp more effectively. If you have a particular issue with Mailchimp or something you’d like answered please leave a comment on this video and I’ll try and create a video for you.

Now Robin asked me recently how images may be resized in Mailchimp. We can crop images in the Mailchimp image editor and we can resize them. In this video I’ll cover resizing and in a separate video I’ll show you how to crop images in Mailchimp.

So let’s go into Mailchimp itself. I’m in Mailchimp and I’m in the campaign editor, the email campaign editor. So there are two places we can resize images. I’ll show you the the easy way; so I’m going to add an image content block, I’ll click “browse” to add an image. I have an image from Wikipedia of my hometown, Brisbane Australia, and we can see that this image is three thousand one hundred and eighty four pixels wide. In other words it’ll be very slow to load for recipients. So Mailchimp says to us “This image is so big it may obliterate inboxes. Images should be around 800 to 1200 pixels wide. So if we click “let’s fix it” what we will notice is that Mailchimp will automatically reduce the size for us. In other words it’s changed the size to a 1200 pixels wide so we don’t need to change it any further, we merely click “Save”. So we just click “let’s fix it” and then click “Save” and Mailchimp did the work for us. So I’ll click “Save” and close. What I’ll do is I’ll now go into the content studio where our images are stored in Mailchimp and I’ll show you how we can reduce the size there. What we will notice if I click on my image and then click “view details” is that Mailchimp has kept the original. The very large file and the smaller one but let’s go to the original large one and I’m going to click “Edit image”. So what I can do is here, I can reduce the size. So all I need to do is manually change the size; so for example if I wanted 800 pixels wide I merely type in 800 and just make sure that the “lock pixels” is checked. We then click “Save” and it’s resized for us. It’s that simple. We’ll see it’s now 800 pixels wide and Mailchimp has kept a version of all the changes I’ve made. And that’s how easy it is to resize images in Mailchimp.

Thanks for joining me.
