Does this upload then download the picture or use the process power of the MAC? It took 5 hours to do 150 large files. I created a Macro in Phohtoshop to do each one in 10 seconds each file. Good lord that is bad slow.

Contento con la aplicación. Hace lo que necesito.

It works and its quick.

Fast, easy, powerful

Great little utility, but why doesn’t it appear when you drop a file onto it?

I wish there were more tutorials or even tooltips within the app!

This is a great app to keep on hand for those times you need to compress a file to upload or email. Super easy - 15 seconds and done. No more fiddling with settings or uploading your file to who knows who online to reduce its size. The compression is MUCH better than IOS native.

it's great, with one big caveat... no documentation. just a list of features, with no idea how to use them. zen mode and filter packs are probably useful but you will have to try them to see what they actually do. after a bit of trial and error, it's quite a usable app.

Really liked the speed and size of the resulting files

Trying to conver from svg and nothing happens, at least it can say that it can’t covert it. Maybe I can use it for other formats in the future.

This revised review concerns Squash in January 2026 and highlights another application on Setapp which has not been updated since 2024, exceeding 400 days. It is difficult to believe that the developer of Squash has been unable to implement any improvements or performance optimisations. I am beginning to think that Setapp’s quality is declining.

Love the app

It works fine, except for saving. Only way to make it work properly, is to quit and restart for a new picture. That make’s it a bit cumbersome

You need it squashed? Well squash will..err..SQUASH it for you! ;-)

this app is a great help. I needed batch export with resizing and renaming for webp files and this was perfect.

Doesn’t optimise PNG.

Infelizmente não está sendo possivel fazer a conversão em massa de arquivos JPG to WEPG, ele só deixa fazer um por vez não importando vários arquivos de uma vez para a conversão.

Muy buena aplicacion

Es buena app

After the app switched from a simple but fun image compression tool to this weird buggy feature cocktail, I find no use for it.
