How to use the App Icon Size Generator
- 1. Choose your imageA square PNG or SVG, ideally 1024 × 1024 px, or use the sample icon.
- 2. Pick icon setsiOS, Android and web are all ticked; untick what you do not need.
- 3. Download the ZIPUnzip and copy each folder into your project.
What is in the ZIP
With all three sets ticked you get 23 PNG icons. The ios folder has the 1024 px App Store icon plus 180, 167, 152, 120, 87, 80, 60, 58 and 40 px versions. The android folder has launcher icons in mipmap-mdpi (48 px) through mipmap-xxxhdpi (192 px) and a 512 px Play Store icon. The web folder has 16, 32 and 48 px favicons, a 180 px apple-touch-icon, 192 and 512 px PWA icons and a 512 px maskable icon, plus site.webmanifest and head-tags.html with the link tags to paste.
Transparent areas are filled with the colour you choose, because Apple rejects App Store icons with transparency.
Quality tips
- Start from 1024 × 1024 px or a vector SVG. Smaller sources look soft at large sizes, and the tool warns you.
- Large downscales are done in halving steps, which keeps small icons sharper than one big resize.
- Keep detail simple: a 16 px favicon has room for a letter or symbol, not a full logo with text.
- The maskable icon adds padding so Android and browsers can crop it to circles or rounded squares without cutting your design.
Recent Xcode versions can generate every iOS size from the single 1024 px image, so many projects need only that file. Android adaptive icons need separate foreground and background layers, which Android Studio's Image Asset tool creates. Your image never leaves your browser; the ZIP is built locally. Draw a starter mark with the logo maker first if you need one.
Frequently asked questions
Why does my icon look blurry at 16 px?
Fine detail disappears at that size. Use a simplified version of the logo, such as one letter, for favicons.
Do I still need favicon.ico?
Modern browsers use the PNG favicons. Some older tools still request /favicon.ico; a 32 px PNG renamed is not a real ICO, so convert it with an ICO tool if you need one.
Is the App Icon Size Generator free?
Yes, the App Icon Size Generator is free. The first time you download your first icon pack, you are asked for your name and WhatsApp number once. After that, this and every other Uncodemy tool opens straight away without the form.
