A focused release-prep tool
Design apps are good at making artwork. App Icon Creator Desktop is for the pass after that: normalize the source image, export Mac and Windows icon formats, and produce a proof sheet you can review before you ship.
Local icon packaging
Turn finished logo art into app icon files you can actually ship.
Create app-ready icon bundles from your artwork — locally, privately, and without memorizing platform icon rules. App Icon Creator Desktop handles ICNS, ICO, PNG sizes, small-size previews, proof sheets, and a local readiness report before you package the app.

Look first
Real screenshots, short explanation.
The screenshots show the current app, the corrected product artwork, and the proof-first workflow.
Why it exists
The annoying part is not drawing the logo. It is packaging it cleanly.
Most icon mistakes happen after the artwork is done: padding changes, small sizes blur, or the wrong file lands in the release folder.
Small-size checks
A mark that looks fine at 1024 px can fall apart in the Dock, Finder, Explorer, or a taskbar. The preview and proof sheet help catch weak silhouettes, cramped padding, and contrast problems while you still have time to adjust.
Repeatable outputs
Use the same artwork and settings to create ICNS, iconset, ICO, Windows PNG sizes, and a standardized app-icon PNG. The point is fewer hand-built export folders and fewer "which size did I miss?" moments.
Local by default
Your source artwork stays on your machine during the app workflow. There is no account, API key, cloud upload, or subscription required to make the files.
Fit and limits
Know what you are downloading.
Each Walter Claw app is intentionally small. If it does not match your problem, skip it.
Good fit
You already have logo art and need repeatable icon outputs that look consistent across Finder, Explorer, docks, launchers, and store assets. For the plain export checklist, see the PNG to ICNS and ICO page.
Not for
It does not replace a designer. It standardizes, checks, and exports the icon assets you provide.
What you get
Standardized PNG, Mac ICNS, iconset, Windows ICO, Windows PNG sizes, preview sheets, and a short QA report.
Product FAQ
App Icon Creator Desktop questions.
Short answers about fit, inputs, outputs, limits, and store link.
Who is App Icon Creator Desktop for?
App Icon Creator Desktop is for developers, small teams, and indie app makers who already have logo or artwork files and want repeatable icon outputs before release.
Why use it instead of exporting icons by hand?
Manual export works until padding, small-size readability, missing file sizes, or mixed Mac and Windows outputs slow down a release. App Icon Creator Desktop puts those export and proofing steps in one local workflow.
What source artwork does it work with?
It starts from PNG, JPG, or WebP artwork that you provide. The page does not claim the app creates original brand artwork.
What output formats does it create?
It creates a standardized app-icon PNG, macOS ICNS, macOS iconset folder, Windows ICO, Windows PNG size set, small-size previews, proof sheets, and a short QA report.
Does it design a new logo or icon from scratch?
No. It standardizes, checks, and exports icon assets from artwork you provide. It does not replace a designer.
Does it guarantee App Store or Microsoft Store acceptance?
No. It helps you inspect generated icon files before release, but it does not guarantee App Store, Microsoft Store, or other platform acceptance.
Where is it currently sold from this page?
This page links the free Mac App Store and Windows Microsoft Store listings.
