Should you convert APNG to ICO?

Yes, if you need a favicon or a Windows icon. Start from a square APNG of at least 256 pixels, with a transparent background if it has one, so every size inside the ICO comes out crisp.

ICO is also the more widely supported of the two: it opens almost everywhere, while APNG is opens in current browsers and apps.

APNG is a PNG that animates, with full color and soft transparency; ICO is a small container that holds the same icon at several sizes. Use ICO for a favicon.ico at the root of a website, or an icon for a Windows program or shortcut.

How to convert APNG to ICO

  1. 01

    Add your APNG

    Drop your APNG image onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to ICO. Change the quality if you want to; the defaults suit most files.

  3. 03

    Save the ICO

    Press convert and save the ICO. Several files come back together as a ZIP.

What changes when APNG becomes ICO

Nothing is discarded

APNG and ICO both keep every pixel, so the picture survives the move intact. You can convert back and forth as often as you like without it degrading.

Transparency is kept

APNG and ICO both support transparency, so transparent backgrounds and soft edges come through unchanged.

Animations become a still

ICO can’t move, so an animated APNG is saved as its first frame. Choose GIF or APNG instead to keep the animation.

One ICO, every size

The ICO holds 16, 24, 32, 48, 64, 128 and 256 pixel versions, each scaled from your APNG and centered on a transparent square. Browsers and Windows pick the size they need.

Expect a much smaller file

APNG: Larger than a GIF of the same animation, but in full color. ICO: A full favicon with every size is usually under 100 KB. Shrinking the file is often the main reason to make this conversion.

This page is put together from our notes on each format, choosing only what is true of APNG and ICO, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Changing a picture’s format is work your browser already knows how to do. Sending your photos to a server first only adds waiting and risk, so nothing is sent.

How to check for yourself

Worth knowing

  • About the APNG. An APNG usually still ends in .png, so an upload form or editor treats it as a still picture and the animation silently disappears.
  • About the ICO. Renaming a PNG to favicon.ico works in some browsers and silently fails in others. A real ICO holds several sizes so each place picks the right one.
  • DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.

Questions

Will converting APNG to ICO lose quality?

No. APNG and ICO are both lossless, so every pixel is kept.

Will the ICO be smaller than the APNG?

Expect a much smaller file. APNG: Larger than a GIF of the same animation, but in full color. ICO: A full favicon with every size is usually under 100 KB. Shrinking the file is often the main reason to make this conversion.
