Why would I need ICO instead of WebP?

ICO is the format Windows expects for application icons, desktop shortcuts, and favicons.

What happens with an animated WebP file?

Only the first frame is converted. Animation is not preserved, and exact frame selection depends on your browser's decoder.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a WebP — the tool checks the RIFF/WEBP signature bytes, not just the filename or extension, before decoding.

Step-by-step conversion

Open /tools/webp-to-ico.
Choose a WebP file — the content is validated before conversion, not just the filename or extension.
Select Convert & download.
Save the .ico file from your browser downloads.

Transparency and file size

Each embedded icon size keeps the source’s alpha channel — this is a genuine ICO container (ICONDIR plus one entry per size), with each size embedded as real PNG-compressed image data.

Source-specific behavior

Animated WebP files convert as a still image — only the first frame is used, and exact frame selection depends on your browser's decoder.

Privacy

Conversion runs locally in your browser. The file is not uploaded to Looty Tools servers for this workflow.
