Your image is processed locally on canvas — nothing is uploaded.
72, 96, 128, 144, 152, 192, 384 and 512 pixels, generated together from a single source image.
Non-square images are scaled to cover and center-cropped, so nothing looks stretched or squished.
A ready-to-paste icons array for manifest.json, matching the filenames you download.
Upload one image and download the icon set it produces.
A web app manifest can request an icon of almost any size, and different platforms pick whichever one fits their context best: a small size for a notification badge, a mid-size one for a home-screen shortcut, and 512x512 for an Android splash screen. Providing the full standard set means your app looks crisp everywhere instead of being scaled up from a single small icon, which tends to look soft or blurry.
Used for notification icons, shortcuts and some launcher contexts where space is limited.
The most common home-screen icon sizes across Android and desktop PWA installs.
512x512 in particular is used to generate the splash screen shown while a PWA launches on Android.
Every size is generated by scaling your image to cover a square canvas and cropping the overflow evenly.
Questions about image requirements, cropping and the manifest snippet.
Any PNG, JPEG or WebP works. Start with a square image at least 512x512 pixels for the sharpest results, since every generated icon is scaled down from what you upload rather than up.
Cropped, not squished. If your image isn't square, it is scaled up to cover the square canvas and center-cropped, so the aspect ratio is preserved and nothing looks stretched.
No. The image never leaves your browser. It is read locally and every size is generated on an in-page canvas, so nothing is uploaded to a server.
Different platforms and contexts request different icon sizes from a web app manifest: small sizes for notifications and shortcuts, larger ones for home-screen icons and app switchers, and 512x512 for splash screens on Android.
Download each PNG into an icons folder in your project, matching the filenames referenced in the snippet, then paste the icons array into the "icons" field of your manifest.json.
