Create PNG icons from 16 to 512 pixels

Developers and site owners can prepare a complete favicon set when launching a page or replacing an older visual identity.

Generate square PNG icons from 16 to 512 pixels using one source image, with the useful sizes ready for your website or application.

How to use

Choose a source image in PNG, JPEG or WebP format that is no bigger than 20 MB.
Pick the square size you need from the list: 16 x 16, 32 x 32, 48 x 48, 180 x 180 or 512 x 512 pixels.
Run the process to create a square PNG icon at the selected dimension.
Check that the subject is still recognizable at a small size, especially for 16 x 16 or 32 x 32.
Download the icon, then repeat the operation for any other sizes your project requires.

Example

A developer is launching a new site and needs a favicon. They start with a square PNG logo, generate a 32 x 32 icon for the browser tab, then return to create a 180 x 180 version for a mobile home screen icon.

Limits and formats

The tool does not redraw the artwork, so a busy source image may become unclear when reduced to 16 x 16 pixels.
Output is a square PNG only; the generator does not produce ICO files or animated icons.
Accepted inputs are PNG, JPEG and WebP, and the source file must stay within the 20 MB limit.

Where processing happens

The icon resizing and PNG export happen inside your browser. Your selected image is not sent out during the process, so the favicon files are created locally on the device you are using.

Frequently asked questions

Which icon sizes can I create?

The available choices are 16 x 16, 32 x 32, 48 x 48, 180 x 180 and 512 x 512 pixels. They cover common needs such as browser tabs, desktop shortcuts and mobile home screens.

Why does my icon look blurry at 16 x 16?

At that size every pixel matters. Logos with small text, thin strokes or complex details lose clarity. Use a simpler source image or generate a larger size for better results.

Can I create several sizes at once?

The interface lets you work with one size at a time. After downloading an icon, reload the source or run the tool again with another dimension from the list.
