Frequently Asked Questions
What image formats can I convert to ICO?
Our converter supports PNG, JPG, JPEG, GIF, WebP, BMP, TIFF, and SVG formats. Simply drag and drop or select your images to get started.
How do I control which image is used for different icon sizes?
You can specify which image handles which size ranges in your ICO file by setting a maximum resolution for each image. Each image covers all sizes up to its maximum setting, with the last image handling any remaining larger sizes. This cascading system ensures optimal quality at different icon sizes.
Is this ICO converter free to use?
Yes! Our ICO converter is completely free to use. There are no hidden fees, registration requirements, or usage limits. Convert as many images as you need.
Are my images uploaded to your servers?
Yes, your images are temporarily uploaded to our server for processing to ensure high-quality ICO files. However, uploaded files are immediately discarded after being processed and are not stored permanently on our servers.
What ICO resolutions should I include?
For favicons, we recommend including 16×16, 32×32, 48×48, and 256×256 pixels. These cover most use cases including browser tabs, bookmarks, and high-DPI displays.
Can I reorder images to change how they handle different icon sizes?
Yes! You can drag and drop images to reorder them. The order determines how sizes are distributed - each image handles sizes up to its maximum setting.
