Icon Foundry
Image → Icon Set Converter
Upload one image and export a full favicon set, iOS app icons, Android app icons, and any custom sizes you need — all cropped to square, resized on-device, and packaged into a single ZIP (plus a real multi-resolution favicon.ico). Nothing leaves your browser.
.zip
Renaming this takes over from the auto-generated name — it stays exactly what you type.
WEB Favicon & browser icons
favicon.ico + PNGs
e.g. favicon-32x32.png · favicon.ico (standard web convention)
iOS iPhone, iPad & App Store
13 sizes
e.g. Icon-App-60x60@2x.png — the @1x / @2x / @3x scale suffix is Apple's own naming convention and matches what Xcode expects, so it stays fixed.
ANDROID Density buckets & Play Store
7 sizes
e.g. android/mipmap-xxhdpi/ic_launcher.png — each density gets its own mipmap-* subfolder with the same file name inside, which is how Android tells them apart. The 512px Play Store icon sits at the top level instead.
