</iframe>IICO is the Windows icon format and the traditional favicon format for websites. A single ICO file is a container that holds the same image at multiple sizes — typically 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 — so the operating system can pick the best fit. Converting a WebP image to ICO produces a ready-to-use favicon from a modern image source.
WebP is an increasingly common source format for web graphics, but browsers cannot use .webp files as favicons directly. The ICO format bridges this gap: it embeds the image at all standard sizes in a single file, ensuring your favicon looks crisp at every resolution — from the browser tab to the desktop shortcut. Each size is rendered from the source WebP and stored as a PNG-embedded frame inside the ICO container.
For best results, use a square WebP image at 256×256 or larger. The converter centers non-square images on a transparent background. The entire process runs locally in your browser — no upload, no server processing, and no signup required.

The generated ICO includes six sizes: 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256. This covers all standard favicon and icon use cases.
Modern browsers support PNG favicons directly. However, ICO remains the most universally compatible format — it works in all browsers including legacy ones. Use ICO when you need maximum compatibility.
No. Non-square images are centered on a transparent background at each size. For best results, use a square image at 256×256 or larger.
