ICO to GIF Converter

Turn ICO icons and favicons into GIF images with a transparent background and a smart 256-colour palette. Want an animation from several icons? The GIF Maker does that.

How to convert ICO to GIF

  1. Add your ICO files. Drop up to 50 ICO files into the box, paste one, or paste a website address to grab its favicon.
  2. Check the size. The largest image inside the icon is ticked. Click other thumbnails to add more sizes.
  3. Set the colours. 256 colours with dithering off keeps icons crisp. Open Transparency to change how soft edges are cut, or fill the background.
  4. Convert and download. Press Convert to GIF. One or two files download directly, more come as a ZIP.

Want the GIF as an icon again? GIF to ICO builds every size from it.

Transparency in GIF

GIF transparency is on or off - a pixel is either fully visible or fully transparent.

Modern icons have soft, half-transparent edges. The Opacity cut decides which of them stay: lower keeps more of the edge, higher trims it.

Placing the GIF on a known colour? Fill the background with that colour and the edges blend perfectly.

Tips

  • Keep dithering off for icons. Flat colours stay clean. Turn it on only for icons with gradients or photos.
  • Making a forum avatar? Pick the largest size and resize it to the avatar size the forum asks for.
  • Too big? Fewer colours or Compress GIF make it smaller.

Frequently Asked Questions

Drop your ICO into the box and press Convert to GIF. The largest size is used and the transparent background is kept.

Yes. GIF transparency is on or off, so soft edges are cut at the Opacity cut you set (50% by default). Fill the background instead if you know the colour behind the GIF.

GIF cannot store half-transparent pixels. Lower the Opacity cut, or fill the background with the colour of the page where the GIF will sit.

Yes. Click the other thumbnails or press All - each size becomes its own GIF.

No. Your browser converts the icon. Only a pasted link from a site that blocks direct downloads goes through our server, and it is not stored.

Convert each icon here, then put the frames together in the GIF Maker.
