Choose the icon size. The website and Windows presets pick sizes for you; the numbered options produce a single size from 16 to 256 pixels.
Choose how to set the output size: keep the original dimensions, enter a width or height while keeping the aspect ratio, or customize both dimensions.
Sets the pixels per inch (0-1000) used when converting to a raster image. Higher DPI gives a sharper result but a larger file. 72-150 is fine for on-screen use, and 300 is the usual choice for printing.
Choose a color using the color picker or enter a hex color value. (eg. #FFFFFF)
Sets how opaque the background is, from 0 (fully transparent) to 1 (fully opaque).

Adobe Illustrator Artwork (AI) is the native file format of Adobe Illustrator, the industry-standard vector graphics editor. Because AI stores artwork as mathematical paths rather than pixels, a logo or illustration can be scaled from a business card to a billboard with no loss of sharpness. AI files also preserve layers, editable text, artboards, and colour profiles, which is why they are the standard deliverable for logo and branding work.

 

How to open an AI file?

Adobe Illustrator is the natural choice and gives full editing access to every layer and path. Adobe Photoshop can also open AI files, but it rasterises them, so the vectors are no longer editable.

 

Inkscape imports most AI files, and CorelDRAW and Affinity Designer read them as well. Many AI files are saved as PDF-compatible, so simply renaming a copy to .pdf will often let any PDF reader display it. To share the artwork as an image, use our AI to PNG or AI to JPG tool.

ICO files contain pixel-based images that can have up to 256 x 256 pixels, 24-bit color, and 8-bit transparency. ICO files offer a convenient place to store and scale the images needed to display the icons so that Windows users can associate an image with an application.

How to open an ICO file?

Use Windows IconMaker to open, edit, and create an ICO file. CorelDRAW is an excellent program for opening, editing, and creating ICO files. To convert ICO files, consider using our online ICO Converter. Often, ICO files are converted to and from other file types to use certain images as icons or to save the icon image into an editable or portable format.


A popular program for manipulating ICO files is GNU Image Manipulation Program (GIMP). ICO is supported by Mac, Linux, and Windows operating systems. Other programs that can open ICO files include Microsoft Paint, Apple Preview, or IrfanView.
