A focused paint app for macOS.
Open an image, mark it up, export. Twelve tools in one native window. Free and open source, in public beta.
brew install --cask joshlin2201/itspaint/itspaint
Or grab the notarised disk image from Releases. Signed, stapled, opens offline.
The markup jobs the built-in tools skip.
macOS Markup cannot number the steps of a bug report or redact a token. Those two are where ItsPaint starts, not where it ends.
Instant Alpha and real transparency
Select connected colour, make it transparent, export a sticker. Deterministic flood with a tolerance you control, no model deciding for you.
Step badges
Click, click, click. Numbered circles that turn a screenshot into a walkthrough, and renumber themselves through undo.
Pixelate
Drag a box over the secret. Mosaic redaction for tokens, emails, and customer names before a screenshot leaves your Mac.
Fifteen shapes, twelve tools
Arrows, callouts, stars, polygons. Solid, dashed, or dotted, with fills. Plus brush nibs from pencil-hard to airbrush.
Eight export formats
The document is a lossless PNG with a JSON sidecar, so it opens anywhere even without the app.
No account. No telemetry. No network code at all.
The claim is checkable, not marketing: the sandbox declares no network entitlement, and there is no URLSession anywhere in the source. MIT licensed, zero third-party dependencies, plain AppKit and SwiftUI. Read the source.
Free and open source.
ItsPaint is in public beta. If it earns a place in your dock, a star helps other people find it.
Requires macOS 14 Sonoma or later. Apple silicon and Intel.
