How to resize an image to 1024x1024
Load your icon artwork
Drag a JPG, PNG, WebP, GIF, or SVG into the tool. SVG and other vector or large source files give the cleanest result when scaled down to the 1024 master.
Set 1024 x 1024 and a fit mode
Pick the App Icon preset or type 1024 in both fields. Use Crop-to-fit to fill the perfect square, Fit-inside with a background fill to keep a non-square logo fully visible, or Stretch only if the source is already square.
Export as PNG and download
Export to PNG for the sharpest edges and full transparency control, then download. Batch several icons at once and grab them all in a single Download-All-as-ZIP.
Why 1024x1024 is the size that matters
1024 x 1024 px is the single master icon both Apple and Google build from. Apple's App Store marketing icon is exactly 1024x1024, and modern Android adaptive icons and Play Store listings are generated from a high-resolution square source too. Make this one asset perfectly clean at a true 1:1 aspect ratio and every smaller size, from the 180px home-screen icon to the tiny 40px notification badge, downscales from it without surprises.
Because the canvas is a perfect square, Crop-to-fit is ideal when your art already fills the frame edge to edge, since the 1:1 ratio means nothing gets distorted, only trimmed evenly. If your logo is wider or taller than it is square, choose Fit-inside and add a solid background fill so the icon stays centered with clean padding instead of being stretched. Note that the App Store icon must be fully opaque with no transparency or rounded corners, so flatten to a JPG or a PNG on a solid background rather than leaving transparent edges, since the platforms apply the rounded mask for you.
Frequently asked questions
What size should an app icon be?
The master app icon is 1024 x 1024 px at a 1:1 square aspect ratio. Both the Apple App Store marketing icon and the high-resolution source for Google Play and Android adaptive icons are built from this 1024x1024 image, and every smaller size is generated from it.
Should my 1024 app icon be PNG or JPG?
Export PNG while you design so you keep crisp edges and a controlled background. For the final App Store upload Apple requires a fully opaque icon with no transparency, so flatten it onto a solid color, exporting either a JPG or a PNG with a filled background works.
Can I resize a non-square logo to 1024x1024?
Yes. Use Fit-inside mode and add a background fill so your wider or taller logo is centered inside the square with even padding. Avoid Stretch, which would distort the artwork; Crop-to-fit instead trims the edges to fill the frame.
Should the icon have rounded corners or transparency?
No. Submit a full square with solid corners and no transparency. Apple and Google apply the rounded-corner mask automatically, so adding your own rounding or transparent edges can cause rejected uploads or visible artifacts.
Is this app icon resizer really free and private?
Yes. It is free, needs no sign-up, and adds no watermark. All resizing happens locally in your browser with no upload, so your icon artwork never leaves your device.
