WEBP to ICO converter: free, fast and secure
Convert WEBP to ICO online for free with ConvertKaro. It is fast, private and works on any phone or computer. Images saved from websites are often WEBP, and many photo editors, printers and upload forms still reject that format. Converting to ICO fixes the “file type not supported” error. ICO is the format browsers use for favicons and Windows uses for app and folder icons.
Unlike most converters, ConvertKaro never uploads your images. The conversion happens on your own device, so it is quicker, there are no file limits, and your photos stay private.

- Adjust the options. Nothing to set: every common icon size is included automatically.

What is WEBP?
WEBP is a modern image format released by Google in 2010. It produces files roughly 25–35% smaller than JPG at similar quality, supports transparency like PNG and can even hold animation. Most websites now serve WEBP to load faster. The catch is compatibility: some older Windows photo viewers, editing apps, printers and upload forms still refuse WEBP files.
What is ICO?
ICO is the icon format used for website favicons and Windows icons. One .ico file can contain several sizes of the same picture (16, 32, 48 up to 256 pixels) so the system can pick the right one for tabs, bookmarks, the taskbar or the desktop.
When should you convert WEBP to ICO?
- Website favicons for the browser tab
- Windows app and shortcut icons
- Folder icons
- Bookmarks and pinned sites
Tips for the best ICO results
- Use a square logo of at least 256×256 pixels with a transparent background. For a full favicon package with Apple and Android icons, use the Favicon Generator.
- You can convert many WEBP files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original WEBP files until you have checked the converted ICO images.
How WEBP to ICO keeps your photos and images private
Most online converters upload your file to their server, process it there and send it back. That costs time, uses your data pack and means a copy of your file sits on someone else’s computer. WEBP to ICO works differently: the page loads the tool into your browser, and your photos and images are processed by your own phone or computer. The file never travels over the internet, so it cannot be leaked, stored or misused.
Using WEBP to ICO on your phone
WEBP to ICO is designed for small screens. Buttons are large, options are simple, and downloads save directly to your phone storage. On iPhone, downloaded files appear in the Files app under Downloads; on Android they go to the Downloads folder.

Frequently asked questions
Will converting WEBP to ICO reduce quality?
Each icon size is resized with high-quality smoothing. Start from a large, square image for the sharpest favicon.
Does ICO keep transparency from WEBP?
Yes. ICO supports transparency, so transparent areas in your WEBP stay transparent.
Can I convert multiple WEBP files to ICO at once?
Yes. Select or drop as many WEBP images as you like. Each one is converted separately, and you can download them all together as a ZIP file.
Why are images on websites saved as WEBP?
Websites use WEBP because it is much smaller than JPG and PNG, which makes pages load faster. When you save such an image, you get a .webp file that some apps cannot open.
Which sizes are inside the ICO file?
The icon contains 16, 32, 48, 64, 128 and 256 pixel versions, which covers browser tabs, bookmarks, the Windows taskbar and desktop shortcuts.
