What Is Pictogram for Mac and Which App Icons Can It Customize?

Pictogram is a macOS utility that lets you replace an app's default icon with a custom one, and it keeps that custom icon in place even after the app updates itself. It works only on macOS 11.0 (Big Sur) or newer, and it cannot change icons for apps that came pre-installed with macOS or apps downloaded from the App Store. If the app you want to restyle is a third-party app installed outside the App Store, Pictogram is built for that case; if it's a system app or an App Store app, Pictogram won't help.

What Pictogram actually does

The core job is narrow and specific: apply a custom icon to a Mac app and make it stick. That second part matters. Many manual icon-swap methods break the moment an app updates, because the update replaces the app bundle and wipes the custom artwork. Pictogram is designed to preserve your custom icons through those updates, so you don't have to redo the work each time an app ships a new version.

The tool is distributed as a beta (version 0.1 at the time of the source page) and is described as free to try. It was created by Neil Sardesai.

Which app icons it can and cannot change

The two exclusions are the practical decision point. System apps like the ones Apple ships with macOS are off-limits, and so is anything you installed through the App Store. That rules out a large share of the apps on a typical Mac, so check your target app before downloading.

How to check whether your app qualifies

1. Locate the app in Finder (usually the Applications folder).
2. Determine how it was installed: if you got it from the App Store, it's excluded; if it's a built-in macOS app, it's excluded.
3. If it's a third-party app you installed directly (for example, from a developer's website or a downloaded installer), it falls within Pictogram's supported range.
4. Confirm your Mac runs macOS 11.0 or newer.

If all four checks pass, Pictogram is a candidate for that app.

Requirements and current status

• OS: macOS 11.0 (Big Sur) or newer. Older versions are not supported.
• Distribution: available as a beta, version 0.1, described on the source page as free to try.
• Scope: custom icons for eligible third-party apps, with persistence across app updates.

Because this is an early beta, treat it as a tool for experimenting with eligible apps rather than a finished, broadly supported product. The source page does not detail pricing beyond the beta being free to try, so don't assume terms for later versions.

When to use it — and when not to

Use Pictogram if you want a consistent, personalized look across third-party Mac apps you installed yourself, and you're tired of custom icons reverting after every update. The update-preservation feature is the main reason to choose it over manual icon replacement.

Skip it if the apps you most want to restyle are Apple's built-in apps or App Store downloads — those are explicitly out of scope, and no amount of configuration will change that. In that case, look for alternatives that support App Store or system apps, or accept that those icons stay as they are.

A quick way to decide: list the apps whose icons bother you, mark each as system, App Store, or direct-install, and see whether any direct-install apps remain. If none do, Pictogram won't solve your problem.
