What you get from ICO to PNG
Icon files are containers. One ICO can hold a 16 pixel version for browser tabs, a 32 pixel version for the taskbar and larger ones for desktops. A PNG holds one picture, so FileKiwi keeps the largest.
| Sizes inside the ICO | Your PNG |
|---|---|
| 16, 32, 48, 256 px | 256 by 256 px |
| 16, 32, 48 px | 48 by 48 px |
| 16 px only | 16 by 16 px |
The PNG is lossless. Every pixel of the chosen size, soft transparent edges included, is copied as it is.
Many website favicons contain only 16 and 32 pixel images. The PNG will be that small, and enlarging it later makes it blurry. If you need the logo bigger, look for the original artwork or the larger icons a site links in its page head.
Favicon to PNG: common uses
- Redesigning a favicon. Get the current one as PNG, edit it, then turn it back with PNG to ICO.
- Documentation and slides. Show an app or website icon in a guide or a presentation.
- Reusing old icons. Keep icons from retired Windows programs or icon packs as normal images.
- Uploading a logo. Many profile and directory forms refuse .ico but take PNG.
- Checking an icon. See what a favicon looks like at its full size before you replace it.
Windows keeps many program icons inside .exe and .dll files. This tool needs a separate .ico file.
To grab a website's favicon, open yourdomain.com/favicon.ico in your browser and save the file. If the downloaded file does not convert, check what it really is with the EXIF Viewer, which detects the true format and warns when the extension does not match.
