Frequently asked questions

What sizes are included? ›

16×16 and 32×32 for browser tabs, 48×48 for Windows, 180×180 for Apple touch icons, and 192×192/512×512 for Android/PWA icons.

What if my image isn’t square? ›

It will be center-cropped to a square before the different sizes are generated.

Is my image uploaded to generate the sizes? ›

No, every size is rendered locally and zipped in your browser.

Troubleshooting

Why does an icon look stretched or off-center? ›

Non-square source images are center-cropped to a square before resizing, so important content near the left/right or top/bottom edges of a very wide or tall photo may be cropped out — start from a roughly square source image for best results.

Why didn’t the ZIP download? ›
