This PNG to ICO converter takes a .png picture and builds a ready-to-use favicon, folder icon, or app icon for free. You pick the sizes and background you need, choose a single multi-size ICO or a zip with one file per size, and download. The whole process runs right here in your browser, so your image never leaves your device.

How to Convert PNG to ICO

Add your PNG image: press Choose Files or drag it into the drop zone. One image at a time, and the file can be up to 5 MB.
Pick your settings: choose the icon sizes to embed, the background colour, and whether the image should be cropped to a square. The icon is rebuilt automatically as you change them.
Download: save the ICO file, or a zip with one file per size when the combine option is off.

Pick the Sizes You Need

An ICO file can hold several images inside one container. This tool lets you select exactly which sizes to embed, from the classic favicon trio up to a full multi-purpose kit: 16 x 16, 24 x 24, 32 x 32, 48 x 48, 64 x 64, 96 x 96, 128 x 128 and 256 x 256 pixels. The 16, 32 and 48 sizes are pre-selected because that is what most browsers want for a tab favicon.

Each size is stored as a lossless PNG inside the ICO, so the icon stays crisp however it is scaled. Windows and browsers pick the copy that fits the taskbar, Start menu, and Explorer view it needs.

One ICO File or One Per Size

The Combine into one multi-size ICO option is turned on by default, so every selected size is packed into a single .ico file. Turn it off to get a zip with a separate .ico for each size you picked, which is handy when different sizes are needed for different jobs, such as a tray icon, a shortcut, and a pinned taskbar shortcut. If you only select one size, you always get a single .ico either way.

Background and Cropping

Pick the background the icon is drawn on: transparent, white, black, or any custom colour. Transparent is ideal for rounded and irregular-shaped icons, because the icon blends into whatever is behind it. Non-square images are centered with the background showing in the margins, so nothing gets stretched out of shape; switch Crop image to square on to fill the whole square instead.

Your Image Never Leaves Your Device

Unlike file converters that upload to a server, this one does all the work in your browser. Your picture is read, resized, and packed into the ICO locally, and nothing is uploaded, stored, or shared. You do not even need an account. Close the tab and every trace of the conversion is gone.

FAQ

Is it free, and is there a watermark?

Yes, it is free with no signup, and the ICO is not watermarked.

Can I use the ICO as a favicon?

Yes, that is the most common use. Save the file as favicon.ico and point your website HTML at it, and browsers will use the embedded sizes automatically.

Which sizes should I include?

For a website favicon, 16, 32 and 48 are enough. For modern Windows app icons, also add 24, 96 and 256. Or just select them all.

What is the difference between the combine option?

With combine on, you get one .ico that holds every selected size. With it off, you get a zip with a separate .ico for each size.

Is ICO the same as PNG?

An ICO is a container that wraps several PNG images of different sizes. The pictures inside stay lossless PNG, so the quality is preserved.

Can I convert more than one image at once?

No — this tool works on one image at a time. Pick a new file to replace the current one.
