Frequently Asked Questions

What are Android Adaptive Icons?

Adaptive Icons (Android 8.0+) use two layers — foreground and background — so the OS can apply different shaped masks (circle, squircle, rounded square) depending on the device. This tool generates both layers automatically, shows you a preview with all three mask shapes, includes safe zone guides, and exports the ic_launcher.xml files ready for your Android project.

What sizes do I need for iOS app icons?

iOS requires a range of sizes from 20×20 to 1024×1024 pixels. The most critical sizes are 180×180 (iPhone), 167×167 (iPad Pro), 152×152 (iPad), and 1024×1024 (App Store). This tool generates all 13 required sizes with one click.

What sizes do I need for Android app icons?

Android uses density-based sizing: 48×48 (mdpi), 72×72 (hdpi), 96×96 (xhdpi), 144×144 (xxhdpi), 192×192 (xxxhdpi), plus 512×512 for the Google Play Store listing.

Is this icon resizer really free?

Yes, completely free with no signup required. It runs entirely in your browser so your images never leave your device. No watermarks are added unless you choose to add one yourself.

Do I need to install any software?

No installation needed. This tool runs in any modern web browser — Chrome, Firefox, Safari, Edge. It works on Windows, Mac, Linux, and even mobile devices.

What image formats are supported?

You can input PNG, JPEG, WebP, SVG, GIF, BMP, and most other image formats. Export is available in PNG (lossless, supports transparency), JPEG (smaller file size), or WebP (modern format, best compression).

Can I resize multiple images at once?

Yes! Switch to the Batch Processing tab, drop in as many images as you want, and they'll all be processed with identical settings and exported in an organized ZIP file.
