Squoosh.app is a free service from Google that compresses large images. What I like is being able to compare the before and after versions of images. It’s amazing to see how advanced the compression schemes are today. Some of the images I tested were compressed down over 90% and to the naked eye the degradation was negligible without zooming.
As you can see above, the image size goes from 4.4 MB to just under 200 KB. That’s amazing. And the image below shows that the image quality is virtually the same for the naked eye.
You can learn more about the app here. Play around with the app and all of the different settings to see what you can do. Here’s a quick tutorial to see how it works.

Final thought:
If you’re using Rise, you don’t really need to worry about compression. Rise will do the work for you. Here’s an example where I inserted the original image (4.4 MB) and the already compressed image (98 KB). In the published output, Rise compressed the original image to 100 KB and as you can see it looks great.
However, if you have a bunch of images to upload, having smaller images may speed up the time it takes to upload your files, especially if you have a slower network connection. Just something to keep in mind.
As a bonus, here’s another site that will do some image compression. And of course, you can always use something like ImageTuner to do batch conversions.
