This is an easy to use but powerful image editor. It supports "layers". Imagine GIMP/Photoshop "light" - most of the features non-professionals need to create awesome images.

This incredible software is originally the amazing work of Mark Pazolli and many others (see the credits in the user guide).

I've cleaned it up to work with the latest OS versions, made some UI updates, some performance and usability improvements, and released it to the world via the App Store !

Longtime user

I’ve been using Seashore since about 2005. Its one of the first things I install on a new Mac. It is the tool that I use to resize, rotate, and adjust the quality/compression of my photos and images from the Internet. Seashore starts up and runs fast, is completely free, and works quite well.

Super easy to use

I get so lost in Adobe Photoshop! This was perfect for me. loaded up two images joined them together and saved the file - I was done in like a minute. This would have taken me 30 inutes on APS for sure. Thank you!

Great Program

I've been using seashore for years to make holiday cards for my family. It's been a wonderful successor to appleworks and macpaint (I'm old!)

It fills that niche. It's easy to get up and running with it, but it has much more depth than easy draw and stuff like that. At the same time, it doesn't have an overwhelming amount of complex tools that you need to learn.

And I have done so much with it!

I'm thrilled that they've updated it. I had partitioned my mac with an older OS, so I could keep using it.
