WebP is a web format that is smaller than JPG and supports transparency and animation. Current browsers open WebP, but support in programs and services is uneven.

ICO is a container format for favicons and Windows icons. When you convert WebP to ICO, it can be used as an icon or favicon. See the comparison below for what changes.

This converter reads the file itself to confirm it is WebP, then converts it to ICO right in your browser. Your image is never uploaded.

What is WebP?

WebP is a web image format Google released in 2010. At the same quality it can be roughly 25-35% smaller than JPG, and it handles lossy and lossless compression, transparency and animation in a single format.

What is ICO?

ICO is the format used for Windows icons and website favicons. Its distinguishing feature is that one file can hold several sizes, such as 16×16, 32×32 and 256×256.

What changes when you convert WebP to ICO

Quality doesn't improve, but it doesn't get worse either

Information lost when WebP was saved can't be recovered. ICO is lossless, so it keeps the image exactly as it is now and later edits and saves add no further degradation. File size will grow, though.

Moving images keep only their first frame

ICO can't hold animation. If your WebP file is animated, only the first frame is converted.

It is fitted into a square of at most 256×256

ICO is limited to 256×256. Larger images are scaled down with their aspect ratio kept, and images that aren't square are centered with the leftover area left transparent.

ICO has no quality setting

ICO is lossless, so the quality slider doesn't apply. Instead, when converting from WebP you can manage file size by resizing (exact width and height, or a percentage).

How the file size changes

ICO holds images of up to 256×256, so a large original shrinks a lot. If the image is already small, the difference is negligible.

When to convert

  • You're making a website favicon or a Windows shortcut icon
  • You're preparing an image for typical ICO uses (website favicons, windows program icons)
  • You want to tidy a WebP file into a format that's easier to edit or archive

WebP → ICO: frequently asked questions

+Does converting WebP to ICO reduce quality?

It doesn't get worse. Information already lost in WebP can't come back, but ICO is lossless, so it preserves the image as it is now.

+What happens to the file size?

ICO holds images of up to 256×256, so a large original shrinks a lot. If the image is already small, the difference is negligible. When conversion finishes, the size of each WebP original and ICO result and the change are shown per file.

+Can animated WebP files be converted?

ICO doesn't support animation, so only the first frame is saved. To keep the motion you need to choose a format that supports animation.

+Why won't my WebP file open?

All current browsers, including Chrome, Edge, Firefox and Safari, support it. Support in editing software and document tools varies by version. In that case, converting WebP to ICO makes it open in more places.

+Is my file uploaded to a server?

No. Your WebP file is read and converted to ICO only inside this browser and is never sent to a server. EXIF data such as shooting location is also removed during conversion.
