The essentials, done properly
Everything you need.
Nothing you don’t.
Pixelcasso brings the familiar power of a desktop editor into a focused Mac workspace. It opens quickly, feels obvious, and lets the image stay centre stage.
Select exactly what you mean
Rectangle, ellipse, lasso, and magic-wand selections make precise edits feel direct, not procedural.
Everyday fixes, one gesture away
Resize, trim, rotate, remove colors, align objects, and export in the formats your work actually needs.
A calmer way to edit
From open to
finished in flow.
No setup ritual. Drop in an image, make the change, and move on with your day.

Familiar by design.

Good to
know.
Can I use Pixelcasso for free?
Yes. Pixelcasso gives you the complete everyday editing toolkit and unlimited editable projects for free, plus PNG and JPG export up to 720p with a small Pixelcasso watermark.
What does Premium unlock?
Premium turns Pixelcasso into your full-resolution export workspace: clean watermark-free files, HEIC, WebP, TIFF, SVG, BMP, GIF, JPEG 2000, the installable plugin library, and Generative Fill. Generative Fill is a beta feature that uses your own OpenAI API key, so OpenAI usage is billed separately by OpenAI.
How does sign-in work?
There is no password. Enter your email and Pixelcasso sends a six-digit, five-minute sign-in code. Your subscription follows that email.
How can I buy Premium?
Founding customers can choose €39 per year or pay €99 once for lifetime Premium. The yearly plan renews at the same €39 founding price while it remains active and can be cancelled before renewal.
