Need help?Convert APNG to ICO Online
Turn an animated PNG into a Windows ICO icon for app icons, desktop shortcuts, or a site favicon. ICO is a still icon format, so the converter takes one frame from your APNG and writes it as an .ico file at standard icon dimensions — the alpha channel from your APNG is carried straight into the icon, so transparent edges and anti-aliasing stay clean.
How to Convert APNG to ICO
- Upload Your APNG File: Drag and drop your
.apngonto the page or click "Upload" to pick it from your device. - Pick an Icon Size: Open Advanced Options and use the Image resolution preset to choose the icon dimension — 256, 128, 64, 48, 32, 24, or 16 pixels. 256 is the largest standard ICO size; 16 and 32 are the classic favicon sizes.
- Confirm the Output Format: The output is locked to ICO for this tool, so the result is a ready-to-use
.icofile. - Convert and Download: Click "Convert" and download your icon. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours. No sign-up, no watermark.
ICO Icon Sizes and Where They Are Used
| Size | Typical use | Notes |
|---|---|---|
| 16 x 16 | Browser-tab favicon, address bar | Smallest standard size; keep the artwork simple at this scale |
| 32 x 32 | Windows taskbar, high-DPI tab favicon | The other essential favicon size alongside 16 |
| 48 x 48 | Windows desktop shortcuts, file explorer | Covers shortcut thumbnails on the desktop |
| 256 x 256 | High-DPI app icons, large icon view | Largest size Microsoft recommends inside an ICO; stored PNG-compressed |
Frequently Asked Questions
Does the ICO keep my APNG animation?
No. The ICO format is a still icon container and does not support animation — that is what the separate ANI format was built for. The converter takes a single frame from your APNG and writes it as a static icon, so the motion is dropped by design.
Which frame of the APNG becomes the icon?
The first frame. By APNG convention the default image is the opening frame, which is also what any viewer without animation support falls back to, so it is the most representative still to lift into an icon. If you need a later frame, export that frame as a PNG first, then convert the PNG to ICO.
Will the transparent background survive the conversion?
Yes. ICO has supported a full 8-bit alpha channel since Windows XP, the same transparency model APNG uses, so semi-transparent edges, drop shadows, and anti-aliased curves carry over without a hard matte. In our testing, a 256-pixel APNG icon with soft transparent corners produced an .ico whose edges stayed clean against both light and dark backgrounds.
What size should I choose for a website favicon?
For a browser favicon, 32 x 32 is the safest single choice and 16 x 16 is the legacy minimum. Per MDN, ICO has the best cross-browser favicon support of any format, which is why a favicon.ico still works everywhere even as PNG and SVG favicons have grown. If you want one master file, pick 256 and let the browser scale it down.
Can I use this ICO as a Windows application or folder icon?
Yes. A .ico produced here works as a desktop shortcut icon, a folder icon, or an application icon on Windows. For an app icon you would usually want a larger size such as 48 or 256 so it stays sharp in the large-icon view, rather than the 16-pixel favicon size.
