Turn a PNG, JPEG, SVG or other image into an .ico icon file for Windows or a website. Choose the sizes inside it, whether the image fits or fills the square, a background and the corner shape.
Processed locally — your image stays on your device.
Making icons for a website? The Favicon Generator also makes the Apple touch icon, web app icons and the HTML. Already have an .ico file? Open it in the Icon Editor.

Choose image
A square image at least 256 pixels wide works best, and an SVG is ideal: Doodleden™ draws it afresh at every icon size, so even 16 pixel icons stay sharp. Doodleden™ opens PNG, JPEG, WebP, GIF, BMP, TIFF, SVG, AVIF, HEIC or ICO images. The image is read in your browser and is not uploaded.

Icon settings
The defaults suit a website favicon. Choose Windows app for a desktop program's icon.
Preview
Each size is shown at its real pixel size. The last picture is the smallest size enlarged, so you can check that it is still clear.
Makes one .ico file holding every size you ticked, in your browser. Your original file is not changed. You can change a setting and create it again.

Your icon
One .ico file with every size inside.
Saves the .ico file. Sizes below 256 pixels are stored as 32-bit bitmaps with transparency, and the 256 pixel size as PNG, the layout Windows and browsers expect.
How to convert an image to ICO
Choose your image. A square image at least 256 pixels wide, or an SVG, gives the sharpest icon.
Pick the sizes: Website for a favicon, Windows app for a program or shortcut icon, or tick the sizes you need.
Choose Fit to show the whole image or Fill to crop it to a square, then a background and corner shape.
Check the preview, select Create icon, and download your .ico file.
Which icon sizes do I need?
Use
Sizes
Website favicon
16, 32 and 48 px. Browsers use 16 and 32 in tabs and bookmarks; 48 suits Windows shortcuts to the site.
Windows program or shortcut
At least 16, 24, 32, 48 and 256 px. Windows picks a size for each view and display scaling; 256 is used for large icons.
Everything
All seven sizes from 16 to 256 px, so Windows rarely has to scale an icon.
The Windows app set, 16, 24, 32, 48 and 256 px, matches the minimum sizes in Microsoft's guidance, Construct your Windows app's icon; including more sizes means Windows scales the icon less often. References reviewed: .
For a website, the Favicon Generator makes favicon.ico together with the Apple touch icon, web app icons, manifest and HTML. To change many images at once, the Bulk Image Resizer can save each as an ICO.
Why an SVG makes the sharpest icon
A 16 pixel icon has very few pixels, so shrinking a large picture to that size can blur thin lines. An SVG is a drawing, not pixels, so Doodleden™ draws it afresh at each size inside the icon instead of shrinking one large copy. If your logo exists as an SVG, use that.

Your image is read and turned into an icon inside your browser. It is not uploaded to a Doodleden™ server, and nothing about it is stored.
