About App Icon Generator
App Icon Generator prepares square PNG source assets for PWA, Apple touch icons and app icon workflows. Crop to a square or keep the full image with padding, generate standard sizes, and preview how the square asset may appear with rounded or circular platform masks.
How to use App Icon Generator
- 1
Choose a PNG, JPG or WebP source image.
- 2
Use Crop to square to select part of the image or Fit with padding to keep the complete image.
- 3
Select the app icon sizes you need, including 180px Apple touch and 192px or 512px PWA sizes.
- 4
Choose a transparent or solid background for the square output canvas.

Preview the icon as a square, rounded icon or circle. The shape preview does not alter the downloaded square PNG.
- 6
Download individual PNG sizes or all selected sizes in one ZIP file.
Tips for better results
- Keep important artwork away from the outer edges because operating systems may apply their own icon masks.
- Use a high-resolution source when you need 512×512 output. The generator does not upscale smaller source images.
- For PWA manifests, 192×192 and 512×512 are commonly used icon sizes.
Frequently asked questions
Does my original image have to be square?
No. You can upload a landscape or portrait image, then either crop a square area or fit the entire image inside a square canvas.
Are rounded corners added to the downloaded app icon?
No. Rounded and circular shapes are previews only. The downloaded PNG stays square so the target platform can apply its own mask.
Will the generator enlarge a small source image?
No. Output sizes that would require upscaling are disabled.
