About this tool

Drop a single high-resolution icon and get the whole ladder of sizes at once: 16, 32, 48, 64, 128, 256, 512, and 1024 pixels, each scaled from the original rather than from a smaller step so small sizes stay sharp. Covers Windows and macOS app icons, Android launcher icons, PWA manifests, favicons, and the 1024 × 1024 App Store icon.

Choose crisp scaling for pixel-art icons and smooth for everything else. For a single .ico file with several sizes inside, use PNG to ICO.

  4. Download the results individually or all at once as a ZIP.

Questions

Which sizes does each platform need?

iOS asks for 1024 × 1024 and generates the rest; Android launcher icons are 48 to 192 px (512 for the Play Store); Windows uses 16 to 256 inside an .ico; PWAs want 192 and 512.

Fill or fit?

Fill crops the edges so the image covers the whole frame, which is right for photos. Fit keeps the whole image and pads the rest, which is right for logos and text.

Can I batch resize?

Yes. Drop several images and each is resized to the selected preset; download them one by one or as a ZIP.

Does it keep transparency?

PNG output keeps transparent areas; JPG output fills them with white. Pick the format that the platform accepts.

Is it free, are files uploaded, which browsers work: the general questions are answered once for the whole site.
