Favicon vs App Icon
Differences, use cases, and when to use each
Last updated: April 6, 2026
Favicons are small browser tab icons (16x16 to 32x32). App icons are the larger icons shown on device home screens and app stores (up to 1024x1024). Modern workflows generate both from a single high-resolution source image.
