About this tool
ICO is the icon format used for favicons and Windows icons. WEBP is a modern format that is usually noticeably smaller than JPG or PNG at similar quality.
WebP keeps transparency and is a good choice for the web, but very old software may not open it. Which icon sizes can be read depends on your browser.
Drop one image or many at once: each file is converted separately in your browser using the canvas, then you download the results one by one or all together as a ZIP. Conversion keeps the original pixel dimensions. Nothing is uploaded, so private photos and documents stay on your device. Very large images (tens of megapixels) can be slow or fail on older phones.
Tips and limits. WebP files are often roughly a quarter to a third smaller than equivalent JPG or PNG, depending on the image.
Format comparison
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| JPG | Lossy | No | Photos, sharing |
| PNG | Lossless | Yes | Logos, screenshots, editing |
| WebP | Lossy or lossless | Yes | Websites |
