Every Chrome extension icon size, from one image
Drop in one big picture — 1024 × 1024 works best — and get back all nine sizes Chrome asks for, ready to download one by one or all at once. Your image never leaves your browser.
1 — Pick your icon
2 — Make every size
Makes 16, 19, 32, 38, 48, 64, 128, 512, and 1024 px — everything your manifest.json, toolbar, and the Chrome Web Store ask for.
3 — Download your sizes
{{ zipError }}
One file, extension-icons.zip, with every size named by its pixel width — 16.png, 19.png, and so on.
4 — Paste into your manifest
Copy didn’t work — the snippet below is selected, press Ctrl+C or Cmd+C.
Add this to your manifest.json. The paths assume the icons live in an icons/ folder next to it — rename them to match your project.
{{ manifestSnippet }}
manifest.json snippet will appear here too.Everything happens on your own device — your pictures are resized right here in the browser and never uploaded anywhere.
