{{ announcement }}

1, Pick your icon

{{ fileName || 'Your picture' }}
{{ imgW }} × {{ imgH }} px

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

Your nine icon sizes will appear here once you generate them.

4, Paste into your manifest

A ready-made 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.
