What is WebP to ICO?

WebP combines excellent compression with alpha transparency, making it a modern, lightweight source for sharp multi-resolution icons. The ICO format can hold several resolutions in one file, letting Windows and browsers automatically pick the best size for each context — from a 16×16 taskbar icon to a 256×256 high-DPI display icon.

This WebP-to-ICO converter runs entirely in your browser using the Canvas API and pure JavaScript, so your image is never uploaded to any server and stays completely private. Each chosen size is embedded as a lossless PNG frame inside the ICO container — the modern, recommended approach. WebP transparency is preserved, so transparent areas remain transparent in the .ico.

It is the fastest way to turn a WebP logo or graphic into a real .ico file for a Windows application, a browser extension, or a website favicon that needs legacy-browser support.

FAQ

How do I convert WebP to ICO?
Upload your WebP image, choose the icon sizes you want to include, and click Download .ico. The conversion happens instantly in your browser with no upload required.
Is my image uploaded to a server?
No. The entire conversion runs locally in your browser using the Canvas API, so your image never leaves your device.
What size should the source image be?
Use a square source of at least 256×256 pixels so every smaller icon size is a sharp downscale rather than a blurry upscale.
