Why use an icon resizer?
App stores and platforms require icons at exact pixel sizes. Manually resizing in Photoshop or Figma is tedious when you need 10+ sizes. This tool generates all sizes from a single source image with proper downscaling quality (bicubic interpolation via Canvas API). Start with the largest size you have — downscaling preserves quality better than upscaling.

Frequently asked questions
What sizes can I resize to?
Any size from 1×1 to 4096×4096 pixels. Choose from presets (iOS, Android, Web, Social) or enter custom dimensions. All sizes are exported as PNG.
Does it preserve transparency?
Yes. If your source image has transparency (PNG, WebP), the resized output keeps the alpha channel intact.
Are my images uploaded?
No. All resizing runs locally in your browser using the Canvas API. Your images never leave your device.
What is the best source size?
Start with the largest icon you have — ideally 1024×1024 or larger. Downscaling preserves quality much better than upscaling small icons.
Can I resize non-square images?
Yes. Each dimension (width × height) can be set independently. The image will be scaled to fit within the target dimensions while preserving aspect ratio.
What formats are supported?
Any image format your browser supports: PNG, JPG, WebP, SVG, GIF, BMP, AVIF. Output is always PNG for maximum quality and transparency support.
Can I download all sizes at once?
Yes. Check the sizes you need and click "Download ZIP" to get all selected sizes in a single ZIP file.
