Frequently Asked Questions (FAQs)
What is an ICO file used for?
An ICO file is an image format. Its primary function is for website favicons, the small images displayed in the browser tab, the address bar, and the bookmarks list. It also appears as icons for desktop app shortcuts and folder icons in Microsoft Windows.
Will my converted ICO file keep its transparent background?
Yes. We maintain full transparency for your PNG file. The alpha stays the same, so the icon looks right on top of any background colors or theme.
Does converting PNG to ICO reduce image quality?
Converting PNG to ICO does not automatically improve image quality. If the image is resized to smaller icon dimensions, some fine details may be lost.
Can I convert multiple PNG files at the same time?
You can use our batch converter to upload multiple PNG files at once. After you upload them, the tool turns each PNG into its own ICO file. Then you can download all at once.
Does this converter consume my internet data when converting large batches?
No. Your image file is processed in your browser and is not uploaded to any external server. However, loading the webpage itself requires an internet connection.
