Hidden padding changes perceived size
Two icons can share the same canvas size while one looks much smaller because the visible artwork is inset inside transparent or background padding.
For app icons that must look right everywhere
Create app icons that read at small sizes.
App Icon Creator turns a logo PNG into standardized macOS and Windows icon assets. Open or drop a source image, correct the visible artwork size, generate icon files, and inspect proof sheets before the app goes into the Dock, taskbar, website, installer, or storefront.
Available now for macOS as a $9.99 direct-download product through secure Lemon Squeezy checkout. The app creates macOS and Windows icon outputs; the current storefront download is the signed and notarized macOS installer.
The problem
Pixel dimensions are not the same thing as visual size.
The release problem that created this product was simple: icons were technically 1024 x 1024, but they did not occupy the same usable visual area in the Dock and taskbar.
Small sizes expose weak artwork
An icon that looks fine at 1024 px may collapse at 64 px, 32 px, or 16 px. Proof sheets force that problem into view.
Release work needs repeatability
Mac Dock icons, Windows taskbar icons, installer icons, website logos, and storefront media should all come from a repeatable source-of-truth export.
Workflow
A short, inspectable pass from logo PNG to icon assets.
The app is built for the moment before release when you need confidence that the icon will look right in real operating-system surfaces.
Start with the logo or app icon artwork you want to standardize for release.
Check how much of the 1024 x 1024 canvas is real artwork versus padding.
Create Mac and Windows icon outputs from the corrected source image.
Use contact sheets and readiness notes to catch scale, edge, and contrast problems before shipping.
Current app screenshot
The working interface is built around proof, not decoration.
The current product interface exposes source loading, output generation, and review evidence in one utility window.
Proof from Walter Claw apps
Tested against the exact icon standardization problem that created it.
App Icon Creator was exercised against ClipScript, Transcript Rescue, and Repro Pack so the product page can show real proof assets rather than a generic mockup.
What it creates
Release-ready icon outputs with evidence attached.
The product is intentionally narrow: take a source image, produce platform icon files, and produce enough evidence to trust the result.
Standardized PNG
A corrected 1024 x 1024 PNG becomes the durable visual source for website, app, and storefront use.
Mac and Windows icon files
Export `.icns` for macOS and `.ico` for Windows from the same corrected source image.
Proof sheets and reports
Generate review artifacts that show small-size readability, visible bounds, and readiness before the release package is built.
