Why painters keep using it

Paintmoo tries to behave like wet paint, not a flat drawing app.

Brushes carry color across the canvas. Light passes blend into heavy ones. Clean tools pull paint back up. That is the whole reason to use it instead of a blank pixel brush.

Brush load

Load a brush, drag it through color, then feel it run thin as you keep painting.

Color mixing

New strokes mix into what is already there instead of replacing it with a flat fill.

Local-only painting

No account, no uploads, no stored gallery on a server you did not ask for.

Common questions

Is Paintmoo free?

Yes. Open the app and paint. There is no paywall and no account gate.

Do I need to install anything?

No. It runs in the browser, so there is nothing to download before you start.

How does digital color mixing work here?

Brushes carry paint, the canvas keeps it wet enough to blend, and clean strokes can still pull color around instead of flattening it.

Is there a server behind this?

No. Paintmoo is client-only. The canvas, palette, and export stay in your browser.

Can I paint online without signing up?

Yes. Open the painting app and start. The extra pages are there if you want the mechanics, not because the app needs onboarding theater.

Does it work on phones and tablets?

Yes. Paintmoo is built for desktop, phone, and tablet browsers.

How do I contact Paintmoo?
