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
Pick a picture in step 1 first.
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.
