Source PNG or logo
Bring the logo or artwork PNG you already have. App Icon Creator standardizes and exports that supplied art; it is not a blank-canvas design tool.
PNG to ICNS + ICO
Create ICNS and ICO app icons from a logo PNG.
App Icon Creator is a focused Mac and Windows desktop app for teams that already have logo or artwork PNGs. Use it to export macOS ICNS, Windows ICO, and PNG app icon files, then review small-size previews, proof sheets, and readiness notes before release.
It does not invent a logo from scratch and it does not replace a designer. Its job is the practical export-and-check pass between finished artwork and your app packaging workflow.

Icon checklist
What this PNG to ICNS and ICO pass is for.
The goal is simple: start with logo artwork you trust, then produce app icon files you can inspect before placing them into a Mac or Windows release.
macOS ICNS export
Create the ICNS app icon file expected in macOS app packaging workflows, then review whether the generated icon still reads at small sizes.
Windows ICO export
Export a Windows ICO app icon from the same source artwork so your Windows build can use an icon file made for that platform.
PNG icon outputs
Keep standardized PNG app icon outputs alongside ICNS and ICO files for places that still need PNG assets, previews, or supporting packaging files.
Small-size proof
An app icon has to survive the tiny versions too.
A logo that looks fine at full size can become muddy in a dock, taskbar, app list, or installer view. Use proof before treating the export as finished.
Visible-size checks
Review whether the supplied artwork remains recognizable after it is turned into app-icon sizes.
Small-size preview
Look at the icon at reduced sizes before assuming the mark will read in a dock, taskbar, launcher, or file browser.
Proof sheets
Use generated proof sheets as a practical review artifact before handing files to a packaging, installer, or release workflow.
Readiness report
Check the readiness notes so obvious export or visibility problems are surfaced before release day.
Plain limit
Good icon files help packaging and presentation, but they do not guarantee App Store, Microsoft Store, or any platform approval.
Workflow
Use it after the logo decision, before the app release.
Keep the roles separate so the tool does not sound bigger than it is.
1. Bring artwork you already chose
Start with a PNG version of your logo or app artwork, whether it came from your own design process or a designer.
2. Export platform files
Generate macOS ICNS, Windows ICO, and PNG icon outputs from that source artwork for the app surfaces that need them.
3. Review proof before release
Inspect small-size previews, proof sheets, and readiness notes before you move the files into your package or store submission workflow.
FAQ
Plain answers about PNG to ICNS and ICO exports.
Short, claim-safe answers before you buy an app icon exporter.
Can App Icon Creator turn a PNG into an ICNS file?
Yes. It is positioned for users who already have logo or artwork PNGs and need standardized macOS ICNS app icon output.
Can it make Windows ICO app icons too?
Yes. Current App Icon Creator copy describes Windows ICO output alongside macOS ICNS and PNG app icon files.
Does it design a logo from scratch?
No. It standardizes, checks, and exports icon files from artwork you provide. It is not a logo design service and does not replace a designer.
What are visible-size checks and proof sheets for?
They help you review whether the supplied artwork still reads at small app-icon sizes and give you proof sheets and readiness notes to inspect before release.
Does this guarantee store approval?
No. Icon files can be prepared and checked, but App Store, Microsoft Store, and other platform approvals are separate review processes.
Where can I get it for Mac or Windows?
