Frequently Asked Questions
Learn how multi-resolution ICO packaging ensures crisp icons across all platforms.
What is an ICO file and how does it support multiple resolutions?
An ICO file is an icon format that stores multiple square icon sizes inside a single .ico file. Web browsers and desktop operating systems automatically pick the sharpest embedded size for the user’s display without blurry scaling.
Which embedded resolutions should I select for a web favicon?
We recommend including 16×16 (browser tab bar), 32×32 (retina browser tabs and bookmarks), 48×48 (desktop taskbars and shortcuts), and 256×256 (high-DPI desktop tiles and app launchers).
What is the difference between Fit, Fill, and Stretch modes?
Fit scales the complete source image proportionally inside the square, adding balanced padding if the source is rectangular. Fill scales the image to cover the square canvas completely. Stretch forces the image into a 1:1 square regardless of original proportions.
Can my generated favicon retain transparency?
Yes. If your source image (PNG, WebP, or SVG) has a transparent background, that transparency is preserved across all embedded icon sizes. You can also uncheck transparency to fill the background with a solid color.
Are my brand logos or images uploaded to a server?
No. All icon scaling and .ico file generation happen 100% locally inside your web browser. No files are ever sent to an external server.
