WebP to ICO Converter
Runs in your browser — your files are never uploaded.
Turn a WebP image into a favicon.ico containing 16, 32 and 48 pixel versions, so every browser and operating system picks the size it wants. Transparency is preserved, which matters for logos that need to sit on both light and dark backgrounds. Non-square images are centre-cropped rather than stretched. Runs entirely in your browser.

Frequently asked questions
Is transparency preserved?+
Yes. Each embedded image is stored as PNG inside the .ico, so the WebP’s alpha channel carries through in full — no hard edges, and the icon sits correctly on any background.
What happens if my image is not square?+
It is centre-cropped to a square before scaling, keeping the middle and trimming the long edges. Squashing a wide logo into a square makes it unreadable at favicon sizes.
Why does the .ico hold three sizes?+
Browser tabs use 16px, bookmarks and shortcuts often 32px, and Windows 48px. Rendering each size separately from the source is far sharper than letting the system rescale a single image.
Do I need anything else for a full favicon setup?+
For a complete package — apple-touch-icon, the various PNG sizes and a web manifest — use PNG to ICO, which produces the whole set as a zip rather than just the .ico.
Are my files uploaded?+
No. The icon is built entirely in your browser on your device. Your image is never uploaded, stored, or logged.
