Create 32x32 ico file

All I had to do was open one of them in Gimp, and the choose "Open as layers.. All layers are automatically created in the correct size, export to ico and presto! When working in GIMP, I always have to save my multi-layered image as png and then open it again and create the multiple layers. That takes very long. There is a nice GIMP plugin called iconify2 that does this. See registry. Using GIMP worked like a charm, great advice! Heads up, if the icon is an SVG it avoids the faff with the 16x16 size.

Note that this command will remove the alpha channel and replace it with white. AbeVoelker I guess if you leave out the "alpha off" it won't do that. I didn't involve also the "-bordercolor white -border 0" parts either. And since my source png was already 64x64, the last part of the clone didn't have the resize. I love command line solutions, but bear in mind that the automatically resized 16x16 will probably look like mush. Icons this small should really be drawn by hand pixel-by-pixel.

It depends on your priorities. Just a note that, yes, the imagemagick example isn't ideal because of the scaling issues and the alpha stuff etc but it gives a neat illustration of what's possible in a single command line. The first example, which assumes you have already created a set of possibly hand-drawn icons at each size, is probably going to give your the best results in a very simple command. You can also merge pngs into an ico through a variety of online tools — KyleMit. As an update to this post: IcoFX is no longer free but does allow 15 evaluation runs.

Do not down-vote this post as it was free at the time of writing. IcoFX worked well for me. I just downloaded it and the limitation now is that the Save function will be disabled after 30 days. The developer has changed that now. I continue to use the old version 1. I don't think the enhancements are worth paying for.

You can probably find a download link if you Google it. Having tried both GIMP and ImageMagick for converting a transparent PNG file to a transparent ICO file, icofx gave a much better image quality for the 32x32 and 16x16 transparent icons - these are the ones that are seen the most as they appear on the task bar and the application icon in the top left hand corner.

There are tools out there to do this, but if you're interested in creating one yourself and already have or can create the images as PNG files, you can do it at no cost. The first thing you need to do is install ImageMagick. This is a cross-platform image manipulation and transformation tool that doesn't have a visual interface. It's a command line utility. It's been a popular tool for years, and many other apps use it under the hood.

For Mac users who use the Homebrew package manager, you can simply type this in Terminal:. This will get you the latest version, and is the recommended method for installation. Use the Homebrew link above to install that first, if necessary. If you would rather install ImageMagick without using Homebrew, you can visit Cactus Labs and download the installer they've put together. Windows users can visit the ImageMagick website and download the installer directly from them.

Use their recommended installer. The others are for special use cases. Now to convert multiple. So, gather your PNG images.
