In short
Export platform-specific icon packs to avoid manual resizing errors.
Use one high-quality master icon, then generate platform-specific packs (iOS, Android, PWA) rather than manually exporting one-off sizes.
Why this works
- Batch generation keeps sizing consistent and reduces human error.
- Platform bundles align with native asset catalog expectations.
- Single-source workflow simplifies updates after brand changes.
When to use this workflow
- You are preparing assets for a new app release.
- You need consistent icon outputs across stores and launchers.
- Your team wants to avoid manual export mistakes.
Step-by-step guide
- Create a clean master icon with sufficient padding.
- Generate platform-specific packs from the same source.
- Validate previews on device/simulator.
- Replace old assets and re-build app bundles.
Common mistakes to avoid
- Using source artwork with tiny text.
- Manual resizing one by one in external editors.
- Mixing old and new icon sets in the same project.
Frequently asked questions
Can one icon design work for both iOS and Android?
Yes, but you should still validate visual fit because each platform renders icons slightly differently.
