Frequently Asked Questions
What image formats can I upload?
Icon Resizer supports PNG, JPG, SVG, and WebP formats. For the best results, use a high-resolution PNG or SVG with a transparent background.
Is this tool free to use?
Yes, Icon Resizer is completely free with no sign-up required.
What does auto-trim do?
Auto-trim automatically detects and removes transparent padding around your image before resizing. This ensures your icon fills the available space without unnecessary whitespace.
What icon sizes are generated?
The sizes depend on the platforms you select. For example, iOS requires sizes from 20×20 to 1024×1024, Android needs mdpi to xxxhdpi, and favicons include 16×16, 32×32, and 48×48.
Are my images stored on your servers?
No. Images are processed in memory and immediately discarded after icon generation. We do not store, share, or retain any uploaded images.
