WebP to ICO Optimization FAQ

Will ICO actually be smaller than WebP?
+
Almost always when going from PNG / JPG / TIFF into WebP or AVIF: expect 25-50% smaller than JPG at the same visual quality, 60-90% smaller than PNG. Going the other way (WebP / AVIF back to ICO = PNG / JPG) typically grows the file because you are leaving a more modern codec for an older one — useful for compatibility, not size.
Transparency survives when ICO supports alpha (PNG, WebP, AVIF, GIF, TIFF, SVG). Converting to JPG flattens the alpha channel onto white — if you need transparency on the modern web target WebP or AVIF instead of ICO.
At quality 80+ on WebP / AVIF the difference is invisible to anyone but a trained eye even at 3x device pixel ratio. Photos compress slightly more visibly than line art; if your WebP is screenshots or UI mockups, push quality to 90 or use a lossless ICO.
Usually not. In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the ICO. There is no setting on this page to keep or remove metadata, so check the result with a metadata viewer if it matters.
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Yes. Uploaded WebP files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted ICO are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Use a `<picture>` element: `<picture><source srcset="image.ICO" type="image/ICO"><img src="image.WebP" alt=""></picture>`. Browsers that understand ICO fetch the smaller file; older browsers fall back to WebP. WebP is supported in 96%+ of installed browsers, AVIF in 90%+.
A WebP that is already heavily compressed (low-quality JPG) often grows when re-encoded into a lossless ICO (PNG / TIFF). A high-bitrate lossless WebP (PNG / TIFF) often shrinks 60-90% when going to a lossy modern ICO (WebP / AVIF). Image content matters too — photos compress very differently from line art and screenshots.

WebP

WebP provides superior lossless and lossy compression for images on the web, developed by Google.

ICO

ICO (Icon) is a popular image file format developed by Microsoft for storing icons in Windows applications. It supports multiple resolutions and color depths, making it ideal for small graphics like icons and favicons. ICO files are commonly used to represent graphical elements on computer interfaces.
