I then go through the images deleting the duplicates and cropping anything extra out. I start by opening all the images within the Preview application on my Mac. This way it was easier to see the larger photos and I could better compare, delete, and crop any images I wanted to. I then highlighted all of them, right-clicked, and opened them in Preview. Each time I started out by moving all of the photos I potentially wanted to use into a directory, also known as a folder, so they’d all be in one place outside of the Photos application. My previous process when going through the photos I potentially wanted to use on my blog relied heavily on the Preview application. Resizing and Compressing Images Using Preview on My Mac….

In case you’re also interested I figured I’d go through how I resized and compressed my images individually using the Preview application on my Mac computer before then going over how I now use ImageMagick ® through my terminal to resize and compress all of the images in my directory at once. Two of the blog posts I found helpful while learning included an article called A few basic (but powerful) ImageMagick commands by Sunny Srinidhi in 2017 on Medium and Smashing Magazine’s article called Efficient Image Resizing With ImageMagick by Dave Newton.

After installing it, using Homebrew through the terminal, I was able to figure out how to resize a single image and then worked on compressing all the images in my directory (or folder). I mentioned the bug to Matt while lamenting over what I should do and he recommended I look into ImageMagick ®.

I’ve only gone through this process on my Mac so the images below will reflect that that said, I see the current release, at this time, of the free ImageMagick® software (version 7.0.10-57) “runs on Linux, Windows, Mac Os X, iOS, Android OS, and others” so a variant of this should work for you regardless of what device you’re on.īack when the quality slider in the Preview application stopped working for me when exporting images on my Mac I realized I wasn’t quite sure how to compress the images I needed to upload to my website’s server. Just in case you’re also looking at resizing and/or compressing your images I figured I’d share what I did with you.

My husband Matt recommended I look into ImageMagick ® and after looking around online I was able to figure out how to resize multiple images at once using my terminal. I normally make my images smaller using the Preview application on my Mac so they’d take up less room on my server but a step in my process had broken and I wasn’t sure how to go about doing that anymore. Several months ago I went to compress the images I planned on uploading for my new blog post and realized that I could no longer follow the same steps I had used before.
