How to Convert PNG to ICO (Without Uploading Your Logos)

If you are a web developer or designer, you know that every website needs a favicon—the little icon that appears in the browser tab. While modern browsers support PNG and SVG favicons, the traditional .ico format is still required for legacy support, enterprise environments, and Windows desktop application icons.

You probably have a beautiful, transparent .png logo ready to go, but you need it in .ico format.

The Problem with Free Icon Generators

Searching for an "ICO generator" yields dozens of free websites. However, nearly all of them operate on the same flawed premise: they force you to upload your proprietary logo to their server.

Why is this an issue?

Intellectual Property Risks: You are sending your unreleased logo or client's branding to a third-party server. You have no control over how long they keep it or who sees it.
Slow Workflows: Waiting for a file to upload, process in a server queue, and download is frustrating when you just need a 16x16 pixel icon.

DuckConvert: The Local ICO Generator

DuckConvert solves this by bringing the image processing software directly into your web browser.

When you convert a PNG to an ICO on our site, your file never leaves your computer. Our tool uses HTML5 Canvas technology to read your PNG and wrap it in the proper Windows Icon header format entirely offline.
