Convert WebP to ICO

Include 16x16, 32x32, 48x48 and 256x256 and you have covered every context Windows and browsers ask for. A single ICO holds all of them, so the operating system picks the nearest match instead of resampling one size down and making it mushy. Start from a square WebP — anything else gets letterboxed or cropped.

No. The compression artefacts already baked into the WebP are ordinary pixel data now, and ICO preserves them perfectly rather than removing them. The file usually gets larger, sometimes several times larger. It is still worth doing before editing, because further edits will not stack a second generation of loss on top. ICO lets one file serve a taskbar, a file listing, a desktop shortcut and a browser tab without any of them looking resampled. WebP is still second-class outside the browser — print workflows, older Office builds and some phone galleries do not accept it.

By default yes, wherever the target has somewhere to put it — camera model, exposure settings, lens and GPS coordinates all carry across. GPS is the field worth thinking about: if the image is going to be published, use the strip-metadata option so you are not broadcasting where the photo was taken. WebP is Google’s 2010 image format, built from the VP8 keyframe encoder and intended to replace JPG, PNG and GIF at once.

Only the first frame survives, because ICO is a still format with nowhere to store the rest. If the animation matters, target a format that animates, or convert to a video container instead and keep the motion. ICO is not a general image format: it is square, small, and no photo editor treats it as a first-class working file.

Transparency survives when ICO is PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background. If you need transparency in the result, target a transparency-aware ICO instead of ICO=JPG. ICO is the Windows icon format, and it is the only image format browsers will accept at /favicon.ico.

Embedded ICC color profiles are read from WebP and re-attached to the ICO output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB, which keeps colors consistent across most modern displays.

Camera EXIF (ISO, shutter, lens, GPS coords) is preserved by default during WebP → ICO when both formats support metadata. Use the privacy option to strip metadata before download if you need to share images without geolocation.

Yes — drag multiple WebP files into the upload zone and we queue them in parallel. Free users get 100 MB per file; Premium has no per-file cap and runs more parallel workers, so a 200-image batch typically finishes in under two minutes.

For straight format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, with the same output quality. The difference is parallel batch handling — desktop apps open one file at a time; we accept a batch.

Default is 1:1 — your ICO keeps the pixel dimensions of the source WebP. If you need to resize as part of the conversion, use /resize-image/ after conversion, or chain it with the /image-resize/ utility.

For JPG / WebP, quality 75-85 typically gets the ICO 60-80% smaller than WebP with no visible difference at normal viewing distance. For lossless ICO (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
