Questions and answers
Before you trust the result: what to know about the format, the limits, your data and the tools next to it.
Smaller files with the same transparency: WebP is typically 25 to 35 percent under PNG at the same look, and an icon's flat colors compress very well. For a page's icons and logos, that is bytes saved on every load.
Yes: Chrome, Firefox, Safari and Edge all show WebP, and have since 2020. Only Internet Explorer never did.
Keep it when the icon sits on different backgrounds or is a UI element. Fill it with a color when it always sits on one known background and you want the smallest file.
90 to 100: an icon's few flat colors and sharp edges compress well at high quality, and the file stays tiny.
Drop the ICO, pick the frame, set the quality, choose Keep or Fill for the transparency and download.
An ICO is a container: a directory of frames, each a PNG or a Windows bitmap at its own size and depth. The tool reads the directory itself, lists every frame and starts on the largest; the Frame choice in the bar switches to another.
No. The ICO is read and its frames decoded by JavaScript on your device; the page makes no request with your file. Load it, go offline and it still works.
No. The ICO to WebP converter is free and opens without a sign-in, an account or an install.
Up to 20 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.
An ICO can hold several sizes. The tool lists the frames, largest first, and converts the one you choose; the download is named with that frame's width. Both PNG and older BMP-style frames are read.
The chosen frame's own size in pixels: the tool doesn't scale an icon up or down.
