WebP to ICO Converter
You have a logo or picture saved as WebP and need an icon file for a favicon or a Windows shortcut. This converter builds an ICO from it on your device, with the icon sizes you tick. Transparent areas stay transparent, and the original image never leaves your browser.
How to convert WEBP to ICO
- Add your WEBP files by dropping them, clicking the drop zone or pasting.
- The output format is already set to ICO. Adjust quality or size if you need to.
- Press Convert and compare the original and new size for each file.
- Download each file or all of them as a ZIP.
When to convert, and when not to
- You need a favicon.ico for a website and your artwork is a WebP.
- A program or shortcut requires an icon in the ICO format.
- You want several icon sizes packed into one file.
- Do not start from a detailed photograph. Tiny icon sizes cannot show fine detail, so a simple, bold design works much better.
What changes
- The result is an ICO containing one PNG-compressed image for each size you tick, from 16 up to 256 pixels. The default is 16, 32 and 48.
- The picture is fitted inside a square without being stretched, so a wide or tall image gets transparent margins.
- Transparency is kept in every size.
- Metadata is not copied.
- An animated WebP becomes one still image.
How the icon sizes work
An ICO file is a container that can hold several versions of the same icon. Programs pick whichever size suits the place where it is shown, such as a browser tab, a taskbar or a desktop shortcut. This tool lets you choose which sizes go inside.
The default selection of 16, 32 and 48 pixels covers the usual favicon needs. Tick larger sizes if the icon will also appear on desktops or in app lists. Every extra size makes the file somewhat bigger, so include only what you will use.
You can include several sizes in a single pass, so there is no need to run the converter again for each one. Tick every size you expect to need, convert once, and keep the single resulting file. If you later realise that an extra size is wanted, just convert again with the new selection and replace the old icon file.
Preparing a WebP so the icon looks sharp
Icons are shown very small, so the artwork must be simple. A bold shape or a short letter mark survives shrinking, while thin lines and small text become a blur. If your WebP is a full logo with a tagline, crop it to the symbol first.
A square source gives the cleanest result. When the image is not square, the tool places it in the middle of a square canvas and leaves the rest transparent, rather than distorting your artwork.
Preview your artwork at the smallest size before converting. Shrink the image in any viewer until it is about the size of a browser tab icon and see whether it is still recognisable. If it is not, simplify the design, remove thin details and increase contrast. That check takes a minute and prevents disappointment later.
Using the ICO on a website
Save the file as favicon.ico and place it where your site expects it, then reference it from the head of your pages. Many sites also publish PNG versions of the icon for modern devices, so keep your original image handy.
After uploading, browsers often cache icons for a long time. If you still see the old one, clear the cache or open the site in a private window to confirm the new icon works.
Keep your original image alongside the ICO. Modern setups often ask for PNG icons in additional sizes, and a good source image lets you create them whenever required. The ICO made here is one useful piece of that set, particularly for older browsers and Windows features that still look for a classic icon file.
Privacy: your files stay on your device
- The tool decodes, resizes and encodes your pictures with your browser. The files are never sent to a server.
- To check it yourself: open the browser developer tools (F12), open the Network tab, convert a file, and look for any request that carries your image. You will see none.
Frequently asked questions
Which icon sizes can I choose?
From 16 up to 256 pixels. The default is 16, 32 and 48, and you can tick others before converting.

It is fitted inside a square without stretching, and the leftover space is transparent.
Can I use this ICO as a favicon?
Yes. Save it as favicon.ico and link to it from your pages.
