Convert images to ICO

Common questions asked about www.icojet.com

Which image formats can I convert, and are there file limits?

You can use PNG, JPEG or JPG, GIF, BMP, and WebP images as the source for an ICO file. The converter accepts files up to 8 MB and 40 megapixels, so check both limits if your image won’t load. The image is checked for an allowed format and reasonable dimensions before it is processed. For the best results, start with a clear, square image; a source image of at least 256 × 256 pixels is recommended if you plan to include the largest icon sizes.

Which icon sizes should I select?

You can choose from 16, 24, 32, 48, 64, 128, and 256 pixel resolutions. The right selection depends on where the icon will appear: 16 and 32 pixels are common for compact interface elements, while 48 and 64 pixels suit desktop views. Larger sizes, such as 128 or 256 pixels, can help on high-density displays. You can include several resolutions in a single ICO file, so the software using the icon can select an appropriate size for its context.

Is my image uploaded or shared when I convert it?

No. Conversion takes place locally in your current browser tab, and your source image is not sent to a conversion server, stored by the service, or shared with a third-party conversion service. The tool reads and processes the selected image using browser APIs on your device. Closing or refreshing the page clears the working data held by the tool. Keep in mind that the ICO file you download is saved to the location chosen by your browser, so you can manage or delete that copy there.

How can I get the clearest results from my image?

Begin with a square image that is at least 256 × 256 pixels and has clear edges. A square source works well because the converter resizes it to each resolution you select. Choosing several sizes lets the ICO include options for different display contexts, from small interface elements to larger views. The converter creates those sizes from your source image, so a clear, suitably sized original is a helpful starting point. You can adjust your selected resolutions before converting without changing the original image.

What will I receive, and how do I choose what goes into it?

The converter produces one downloadable, standards-compatible ICO file containing the resolutions you selected. You can choose one size or combine several, from 16 × 16 up to 256 × 256 pixels. Including multiple sizes allows Windows, desktop software, and browsers to choose the sharpest included version for a particular context. Before converting, review the size selection to make sure it covers your intended use. You can change that selection without modifying your source image, then download the resulting ICO file.
