About the ICO to WebP Converter

Why convert ICO to WebP?

If you want an icon as a lightweight web image that still keeps its transparency, WebP is the modern pick. Converting ICO to WebP extracts the icon and re-encodes it as a compact, high-quality file — smaller than PNG, with a full alpha channel — ready to drop into a website.

You choose the quality, transparency is preserved, and everything runs in your browser, so your icons never leave your device.

How to Use This Tool

  1. Add your ICO files. Click to upload, drag & drop, or paste — up to 30 at once.
  2. Choose the quality. Higher keeps more detail, lower makes smaller files — 80–90% is a sweet spot for most images.
  3. Resize if needed. Enter a width in pixels to scale every image; leave it blank to keep the original size.
  4. Download. Save files individually, or hit Download all for the whole batch.
