Frequently asked questions

How do I generate app icon sizes from an image?
Upload a PNG, JPG, WEBP, or GIF image, choose the sizes you need, then click Generate icon sizes. Each export uses your original filename with the size appended, such as my-logo-1024px.png. Download files individually or use Download All for a ZIP archive.
Is this app icon generator free?
Yes. This tool is completely free with no account required. There are no usage limits on how many icon sets you can generate.
Are my images uploaded to a server?
No. Resizing runs locally in your browser using the Canvas API. Your image never leaves your device.
What icon sizes does this tool export?
You can export 1024px, 512px, 256px, 128px, 64px, 32px, 24px, 20px, and 16px square PNG icons. Select all sizes or pick only the ones you need. These cover common app store, PWA, desktop, and favicon requirements.
What happens if my image is not square?
The tool center-crops your image to a square using the shortest side, then resizes that square to each export size. For best results, upload artwork that is already square or has important content centered.
Which image formats are supported?
You can upload PNG, JPG, JPEG, WEBP, or GIF files. All exports are saved as PNG to preserve transparency when your source image supports it.

About this tool

Why generate multiple icon sizes?

Apps, PWAs, and operating systems expect icons at specific pixel dimensions. App stores often require a 1024px master icon, while browser tabs, taskbars, and menus use smaller sizes like 32px, 24px, or 16px. Generating the full set upfront saves time when shipping software or updating a website favicon.

Where are these icon sizes used?

1024px is common for iOS and macOS app submissions. 512px and 256px work well for Android, desktop apps, and marketing assets. 128px and 64px suit store listings and medium UI placements. 32px, 24px, 20px, and 16px map to favicons, toolbar icons, and small UI elements across web and desktop platforms.

Tips for better icon exports

Start with a high-resolution square image when possible. Simple logos and flat artwork resize cleanly to small sizes. If your source is rectangular, keep the subject centered so the automatic square crop does not cut off important details.

Is browser-based icon generation private?

Yes. This generator processes files entirely in your browser, so your brand assets are not transmitted to Vidsembly or any third-party server. That makes it suitable for unreleased apps, client work, and internal products.
