I can wait, but needs a progress bar

Took 10MB off a 38MB PNG image. Also took an hour to do it on my 2017 Retina Macbook 12”. I can wait, but I need to have an idea of how long it will take.

Does what it says

I’ve had and used this app for quite some time now and I need to remember to use it more often. If only the rest of the Internet would use such apps like this more often the Internet as a whole would be so much better-off.

This app really does exactly what they say it does. For highly-compressed JPEG files I still manage to squash an average of 25K out of them. Sure, 25K may seem like nothing, especially in these days of broadband, but every kilobyte saved adds-up. Imagine those graphic-heavy pages, 10 images would be 250K saved. 25 would be 750K. Seriously. I remember the days when a 25K file would take 20 minutes to download. Just because we have blazing speed with broadband these days is really no excuse for not optimizing your images for the Internet.

And it’s not just web pages. An optimized image plopped into your MS Word file makes that Word file smaller. And when that Word file is converted into a PDF file that PDF file is smaller.

Get a clue, people, get this (or something equally as useful) and optimize your junk before plugging up my bandwidth! Hahahah

Great app

I just put 250 huge JPGs from my photographer (about 4GB worth) into Squash and was able to remove about 2.2GB. I was amazed. I've been using Squash for a couple years now and it always works when I need it. One feature request I would have is to be able to batch resize and change dpi. It would be great to take a large 300dpi pic and not only Squash it, but change all the pics to a certain percentage of resolution size and to set the DPI. right now I do that individually in Preview but it is annoying. This app is anything but.
