Chrome Extension Icon Generator — 16/32/48/128 Bundle

Toolbar, management, and Web Store icons — all sizes in one bundle.

About this

Chrome (and Edge, and Brave) extensions require icons at four specific sizes: 16×16 for the toolbar action button, 32×32 for Windows display, 48×48 for the chrome://extensions management page, and 128×128 for the Chrome Web Store listing. The smallest must remain legible at toolbar scale. Vanikya generates the artwork and exports all four sizes ready to drop into your /icons folder.

A snippet of manifest.json is included with the correct icons declaration for Manifest V3 extensions.

What you get

  • Toolbar-legible 16×16 — The hardest size to design — Vanikya's variant ensures the 16×16 reads cleanly even at minimum toolbar density.
  • Web Store 128×128 — The Chrome Web Store listing icon, the one that earns the install click — composed to stand out among the directory's crowded grid.
  • Manifest V3 JSON snippet — Drop-in icons declaration matching Manifest V3 schema — paste directly into your existing manifest.json.

Common questions

Does it work for Firefox extensions too?

Yes — Firefox uses the same icon size conventions. The exported bundle drops directly into a Firefox extension manifest with no changes.

What's the most important size to get right?

16×16 (toolbar) and 128×128 (Web Store listing) carry the most weight. The toolbar icon is what users see every day; the Web Store icon decides whether they install in the first place.

Can I match my Chrome extension's existing visual identity?

Yes — drop a reference image (your existing extension popup or website hero) and the model matches palette and visual language across the generated icon set.
