WebP to ICO converter

    WebP to ICO

    Sizes in the icon

    Everything happens in your browser. Your files are not uploaded.

    How it works

    1. Choose your WebP files

      Drop them into the box, choose them on your device or paste with Ctrl+V.

    2. Converted automatically

      Each file is converted to ICO straight away in your browser.

    3. Download

      File by file, or everything at once as a ZIP file.

    When a WebP ends up as your logo

    Right-click a logo on a modern website, or download an image from a CMS, and there is a fair chance that you get a .webp file. The format is smaller than PNG and JPG and supports transparency, but icon editors, older Windows software and many upload forms do not know it. An ICO does work everywhere, and this page makes it without a detour through another program.

    Two kinds of WebP behave differently:

    • Lossless or with alpha: the transparency is carried into the icon, so a logo without background stays without background.
    • Lossy without alpha: the picture has a solid background and, like a JPG, it will be a solid square in the icon. Remove the background first with the background remover if you want it transparent.

    Check the quality of the source

    A WebP from a website is usually made for the screen and often small, for example 200 × 200 pixels or less. The converter fits the image into every icon size, so a small source is scaled up for the larger sizes. For a favicon, 16, 32 and 48 pixels will look fine; the 256 pixel size will not be sharp. Look for the original logo file if you need a large Windows icon, or use WebP to PNG if you need a lossless copy first for editing.

    Crop the image to a square before converting if there is empty space around the logo. Crop image can do that in a few clicks, and a tight crop makes the icon look bigger at 16 pixels.

    Putting the ICO on your site

    Save the result as favicon.ico in the root of your site and link it in your <head>:

    <link rel="icon" href="/favicon.ico" sizes="32x32">

    Browsers, bookmarks and crawlers all look for this file. For an SVG icon and the iPhone and Android versions, see how to make a favicon.

    Frequently asked questions

    Is my WebP uploaded?

    No. The WebP is decoded and the ICO is built in your browser, so the file stays on your device. There is no limit on the file size or the number of files, apart from your device's memory.

    Is the transparency of my WebP kept?

    Yes. A WebP with an alpha channel keeps its transparent areas in every size of the icon. A lossy WebP without transparency has a solid background, like a JPG.

    Why is my image a WebP at all?

    Many websites, content management systems and social networks now serve WebP, so "Save image as" often gives you a .webp file. Most icon tools and older versions of Windows software do not accept it, which is where this conversion helps.

    Does WebP work as a favicon directly?

    No. Browsers expect ICO, PNG or SVG for the favicon. WebP is meant for images in a page, so convert your logo to ICO and, if you want, to PNG for the other icon files.

    Will compression artefacts show up in the icon?

    A lossy WebP can contain blocky or smudged edges. At 16 or 32 pixels they are mostly scaled away, but at 256 pixels you may see them. If the logo is available as PNG or SVG, use that instead.
