What you bring, what you leave with.

Source.ico

ICO

ICO is the Windows favicon format. Pixelmint wraps a PNG inside a single-frame ICO container — ideal for browser tabs and desktop shortcuts.

Target.webp

WebP

WebP is a modern Google-developed format that beats JPG and PNG on file size at the same quality. Supports both lossy and lossless modes plus transparency.

On the matter

Why convert ICO to WebP.

WebP files are typically 25-35% smaller than ICO at visually identical quality, which makes them the modern default for the web. Converting ICO to WebP reduces page weight, improves Core Web Vitals, and shortens load times — especially on mobile.

The procedure.

  1. 01Open this page in any modern browser.
  2. 02Drop a .ico file onto the zone above, or click to pick.
  3. 03Adjust quality if needed.
  4. 04Download your .webp. Nothing is uploaded.

Correspondence

Letters to the editor.

Q.01How do I convert ICO to WebP?+
A.01

Drop your ICO file onto the converter above (or click to pick one), then hit Convert. Your WebP download starts the moment the encoder finishes — usually under a second. Nothing leaves your device.

Q.02Is converting ICO to WebP lossless?+
A.02

No. WebP uses lossy compression by default. You can tune the quality slider to trade file size for fidelity. Quality 90 is a good default that beats most online tools.

Q.03Will my ICO files be uploaded to a server?+
A.03

No. Pixelmint runs the entire conversion in your browser using the Canvas API. Your image bytes never touch our servers, which is why this is safe for confidential screenshots, IDs, and proprietary artwork.

Q.04Is there a file size limit?+
A.04

There's no hard limit, but very large images (over ~50 megapixels) can be slow on low-RAM devices because everything happens locally. Most browsers cap canvas size around 32,767 pixels per side.

Q.05Does it cost anything?+
A.05

No. ICO to WebP conversion is free, unlimited, and has no watermarks, signups, ads on the file, or hidden tiers.
