iOS Icon Generator
Source image
Square master (e.g. 1024×1024). Max 15 MB.
Cómo usar
- Upload a square master icon (1024×1024 recommended). Processing runs locally in your browser — nothing is uploaded.
- Download the ZIP, then copy AppIcon.appiconset into Assets.xcassets in your Xcode project.
- Clean build, run on simulator or device, and confirm icons pass App Store validation.
Preguntas frecuentes
Is this a secure iOS icon generator? Does it upload my image?
Yes — it is a privacy-first developer tool. All resizing and ZIP packaging runs locally in your browser via Canvas APIs. Your source artwork never leaves your device and is not sent to any server.
What iOS app icon sizes does this tool generate?
It exports the full AppIcon.appiconset: 20–83.5 pt variants at @1x/@2x/@3x (20 px through 180 px for iPhone home screen), plus 1024×1024 App Store marketing artwork and bundled Contents.json.
Where do I copy the ZIP contents in Xcode?
Unzip the download and replace your project's Assets.xcassets/AppIcon.appiconset folder with the ios/AppIcon.appiconset from the ZIP (all PNGs plus Contents.json). In React Native or Flutter, use ios/<AppName>/Images.xcassets or ios/Runner/Assets.xcassets respectively.
Should I include rounded corners in the source icon?
No. iOS applies corner masking automatically — upload a full-bleed square PNG without pre-rounded corners.
Introduction
This secure app icon generator exports every size Apple requires in an AppIcon.appiconset — from 20 pt notification icons through 1024 × 1024 App Store artwork — from a single square master image. It is built as a privacy-first developer tool: unreleased app branding stays on your machine because processing runs entirely in your browser.
Privacy-first local processing
Unlike cloud-based icon services, this tool never uploads your source image. When you choose a file, the browser reads it locally, resizes each variant with the Canvas API, and assembles the ZIP on your device. No account, no API key, and no server-side storage — ideal when you are working on pre-release apps, client NDA assets, or unreleased rebrand artwork.
Developers searching for a secure app icon generator or privacy-first developer tools get the same workflow as server-based alternatives without the data-exposure risk.
iOS app icon size standards
Apple defines icons in points (pt) and exports pixels (px) at @1x, @2x, or @3x scale. The table below lists the key outputs this tool generates inside AppIcon.appiconset.
| Role | Point size | Scale | Output (px) | Typical use |
|---|---|---|---|---|
| Notification | 20 × 20 | @2x / @3x | 40 / 60 | iPhone notification bar |
| Settings | 29 × 29 | @1x / @2x / @3x | 29 / 58 / 87 | Settings, Spotlight search |
| Spotlight | 40 × 40 | @1x / @2x / @3x | 40 / 80 / 120 | Spotlight results |
| iPhone app | 60 × 60 | @2x / @3x | 120 / 180 | Home screen (iPhone) |
| iPad app | 76 × 76 | @1x / @2x | 76 / 152 | Home screen (iPad) |
| iPad Pro | 83.5 × 83.5 | @2x | 167 | Home screen (iPad Pro) |
| App Store | 1024 × 1024 | @1x | 1024 | App Store Connect listing |
The ZIP also includes a pre-filled Contents.json that maps each filename to its idiom, size, and scale — ready for Xcode's asset catalog.
Copy generated icons into Xcode
After downloading the ZIP, integration takes under a minute:
- Unzip the archive — you will see an
ios/folder withAppIcon.appiconset/(PNG files +Contents.json) and optionaliTunesArtwork@*.pngfiles. - In Xcode, locate your asset catalog:
YourProject/Assets.xcassets/AppIcon.appiconset(Swift/Obj-C projects). React Native usesios/<AppName>/Images.xcassets/AppIcon.appiconset; Flutter usesios/Runner/Assets.xcassets/AppIcon.appiconset. - Replace the existing
AppIcon.appiconsetfolder with the one from the ZIP, or copy each PNG andContents.jsoninto the existing folder, overwriting old files. - In Xcode, confirm App Icons and Launch Images → App Icon Source points to
AppIconin your target's General tab. - Product → Clean Build Folder, then rebuild. Run on a simulator to verify the home-screen icon; upload the 1024 × 1024 asset to App Store Connect when submitting.
Do not add rounded corners to PNGs — iOS masks icons automatically at runtime.
Key Features
- Secure local processing — source artwork never leaves your browser.
- Full
AppIcon.appiconsetwithContents.jsonfor Xcode asset catalogs. - iPhone, iPad, and App Store marketing sizes in one ZIP download.
Common Use Cases
- Preparing icon assets for a first App Store submission without sending branding to a third-party server.
- Updating icon sets after a brand refresh.
- Regenerating missing sizes for an existing iOS or cross-platform project.
Best Practices
- Design with strong contrast and simple shapes — fine detail disappears below 60 px.
- Validate icons in both light and dark Home Screen appearances.
- Keep original vector artwork for future scale adjustments; upload full-bleed squares without pre-rounded corners.
