WebP vs ICO: format comparison
| WebP | ICO | |
|---|---|---|
| Primary use | Web images & photos (compression) | Windows icons & favicons |
| Transparency | ✅ Yes (8-bit alpha) | ✅ Yes (32-bit BMP or PNG) |
| Animation | ✅ Animated WebP | ❌ Static only (first frame is used) |
| Multiple sizes | ❌ One size per file | ✅ One file can hold 16–256px |
| Where it runs | All modern browsers | Windows, browsers (favicon), apps |
| Why convert | — | WebP can't be used as a favicon.ico or Windows icon directly |
Convert WebP to ICO at 256×256 or any other size
The ICO format can store icons from 16×16 (small browser tab) to 256×256 (Windows 10/11 high-DPI). Instead of hunting for a WebP that happens to be the right size, use the size presets here: the converter scales your image to 16, 32, 48, 64, 128, 180, 192 or 256 pixels — or type any custom size. A 256×256 WebP to ICO conversion is the most common request because that is the largest size Windows and macOS recognize natively, and it is automatically downscaled into every smaller size inside the same .ico file.
Lossless and high-quality WebP to ICO output
Many free converters visibly degrade icons, which matters at 16×16 where every pixel counts. This tool offers three scaling levels: Lossless keeps the original PNG data inside the ICO (no quality loss at all), High uses high-quality resampling for sharp edges, and Balanced is the fastest. The quality setting also controls background handling: when your WebP has no alpha channel, white-fill and keep-alpha modes give you predictable results on light or dark sites. After conversion, inspect the preview grid — you can judge legibility at every size before downloading.
Why is my icon blurry at 16×16?
Small sizes lose detail because the source image is downscaled. Best practice: start from a large, simple shape (a 256×256 icon with high contrast and bold shapes survives 16×16 best). The preview grid in the result panel lets you check this before you commit to the download.
Frequently asked questions
Is it free to convert WebP to ICO?
Yes — completely free, with no limits, no registration and no watermark. This page has no paywall and no file-count restrictions for normal use.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser using JavaScript. Your files never leave your device — you can even unplug your internet after opening the page and the tool still works.
Can I use the output as a website favicon?
Yes — that is the main use case. Choose the "Favicon set" mode to get favicon.ico, PNG icons at 16/32/180/192px, apple-touch-icon, site.webmanifest and the HTML code to paste into your site's head. Browsers request multiple sizes, so the full set gives the sharpest result everywhere.
What sizes should a favicon be?
Minimum you need: favicon.ico (16+32+48 inside one file), favicon-32x32.png and favicon-16x16.png. For best results on all platforms add apple-touch-icon.png (180×180), android-chrome-192x192.png and android-chrome-512x512.png. The favicon-set mode generates all of these automatically.
Can an animated WebP be converted?
ICO is a static format, so the first frame is used. If you need an animated favicon, browsers no longer support animated favicons anyway — a static, high-contrast icon is the right choice.
Does converting reduce image quality?
With the "Lossless" quality option, the icon is stored as PNG data inside the ICO — mathematically identical to the source. With "High" or "Balanced", resampling may soften edges when scaling down. For small icons use Lossless + a large source image.
