What icon sizes does a Microsoft Edge extension need?

Edge extensions need icons at 16×16, 32×32, 48×48, and 128×128 pixels. Additionally, a 300×300 store logo is required for the Microsoft Partner Center store listing.

Are Edge extension icons the same as Chrome extension icons?

Mostly yes — Edge extensions use the Chromium-based manifest format, so the same icon sizes (16, 32, 48, 128) apply. The difference is the store listing: Edge requires a 300×300 store logo for the Microsoft Partner Center.

What format should Edge extension icons be?

PNG format is required. Transparency is supported and recommended for toolbar icons.

Are my images uploaded to a server?

No. All processing happens entirely in your browser using the Canvas API. Your images never leave your device.

Can I submit the same extension package to both Chrome and Edge stores?

Yes. Since Edge uses the Chromium manifest format, your existing Chrome extension package works in Edge without modification. You only need to create a separate 300×300 store logo specifically for the Microsoft Partner Center listing.

Does Microsoft Edge support SVG icons for extensions?

No. Like Chrome, Edge requires PNG icons in the extension manifest. SVG is not supported for manifest icon declarations. Export your icons as PNG at 16, 32, 48, and 128 pixels before uploading to Partner Center.

Edge Extension Icon Generator — All Sizes for Microsoft Edge

Why Use This Tool?

Microsoft Edge is now built on Chromium and has a large installed base, particularly in enterprise environments where it's the default browser. Publishing on the Microsoft Partner Center (Edge Add-ons store) follows a similar flow to the Chrome Web Store but has a unique 300×300 store logo requirement. This tool generates everything you need in one go.

Privacy First — 100% Client-Side

Your images are processed entirely in your browser using the HTML5 Canvas API. Nothing is uploaded to any server. You can verify this by disconnecting from the internet after loading the page — the tool works offline.

Tip: If you already publish a Chrome extension, your Edge extension can use the same manifest.json icon files (16, 32, 48, 128px). The only new asset you need specifically for Edge is the 300×300 store logo for Microsoft Partner Center.

Tips for Edge Extension Icons

300×300 store logo is Edge-specific — not required for Chrome. This square logo appears in the Edge Add-ons store listing and Partner Center dashboard.
Reuse Chrome icons — since Edge runs on Chromium, your existing Chrome extension icons work directly. The extension manifest is compatible between the two browsers.
PNG with transparency for toolbar icons — Edge respects browser themes, and transparent icon backgrounds blend naturally with the Edge UI in both light and dark mode.
Edge has a large enterprise user base — if your extension targets enterprise users, ensure the icon looks professional and trustworthy.
Test your extension in both the consumer Edge (edge://extensions) and the enterprise-managed version to ensure icons display correctly.
