Create Icons from Images

Import your images and convert them into icons recognized by Windows. Select the whole picture or only a part of it, define the size and color depth of the future icon image, and GConvert handles the resizing and the color conversion: you get a new icon ready to be completed, edited or exported to an ICO file.

Which images can become icons?

GConvert natively imports bitmaps (BMP), Portable Network Graphic files (PNG), Adobe Photoshop files (PSD), Windows icon files (ICO), mouse cursors (CUR) and Macintosh icon files (ICNS, RSRC). Plug-ins add GIF, JPEG and more. An image can also be pasted straight from the clipboard, and the alpha channel of a 32-bit bitmap, a PNG or a PSD file is imported with the picture.

Choose the part, the size and the colors

Choose File | Convert picture to icon, or Import a picture as image in the icon editor. The Import Picture window shows the picture with a selection rectangle that you move and resize, or set by its coordinates, to import a detail of a large picture or the whole image. Then set the width and height of the new icon image, from the predefined icon sizes or any custom size, and its color depth from monochrome to 32-bit with alpha channel. Resizing and color conversion are automatic.

Complete the icon with generated images

A Windows icon usually holds several images. Once the first image is created, Generate other images produces the 48×48, 32×32, 16×16 and other variants you list, in the color depths you want, from that single source, with transparency preserved. Export the result as an ICO file or add it to an icon library.

Batch-create icons, and favicons too

File | Batch Create Icons from Images converts several image files into their ICO equivalents in one operation: pick a destination folder, add the files, press OK. A website icon is a special case of the same workflow: import the source image, keep only 16×16 images in the icon, and export it as favicon.ico.
