Why convert ICO to WEBP?
WEBP is a modern, web-friendly format with alpha transparency support and typically smaller file sizes than ICO. This tool lets you adjust quality, optionally resize, and download results individually or as a ZIP.
Tips
- For favicons, set exact sizes with Fill/Crop (e.g. 32×32, 64×64).
- Transparency is preserved automatically.
- We never upload images—everything runs in your browser.
