Why convert WebP to ICO?
WebP is lossy (web delivery when you want smaller files with alpha support). ICO is lossless (icons and favicons that need the ICO container). Converting WebP to ICO remaps pixels into the target container in your browser.
What changes in the file
- Output is lossless ICO; existing WebP artifacts are preserved, not repaired
- Transparency is supported in the ICO output
- You can resize, adjust quality where relevant, and strip EXIF on export
- Conversion runs on this device — the file is not uploaded
How to convert WebP to ICO
- Drop one or more WebP files onto the converter (or pick them from disk).

- Download the converted ICO file — processing never left your browser.
About WebP
WebP is a modern web image format from Google. It can encode lossy or lossless images and supports transparency, often beating JPG and PNG on size at similar visual quality.
About ICO
ICO is the Windows icon container format. It can hold one or more raster images at different sizes and is still used for favicons and desktop shortcuts.
Common questions
Is this WebP to ICO converter free?
Yes. Formatly converts WebP to ICO in the browser at no charge and without an account.
Do you upload my WebP files?
No. Decoding and encoding run locally with browser APIs and WebAssembly codecs when needed. Files stay on this device.
Will converting WebP to ICO reduce quality?
ICO is lossless, so the export keeps the decoded pixels. If the source was already lossy (WebP), prior compression artifacts remain.
