Why convert GIF to ICO?

  • One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.
  • Browsers show the ICO as your site’s tab and bookmark icon when you save it as favicon.ico.

What to expect when converting GIF to ICO

  • ICO can’t hold this animation, so an animated GIF is saved as its first frame.
  • Icons are square, so a non-square image is centred on a transparent square. Sizes larger than your image aren’t created, so start from at least 256 × 256 pixels.

Frequently asked questions

How do I convert GIF to ICO?
Upload your GIF file above. It is converted to ICO automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.
Does converting GIF to ICO lose quality?
Each icon size is scaled down from your image and stored without further compression, so small sizes stay crisp.
Will the ICO keep the transparent background?
Yes. ICO supports smooth, partial transparency, so transparent areas stay transparent.
Will the animation be kept?
No. ICO can’t hold animation, so an animated GIF is saved as its first frame.
GIF or ICO: which should I use?
Use GIF for short animations, stickers and flat-colour graphics. Use ICO for website favicons and Windows app or shortcut icons. Keep in mind the main drawback of ICO: icons are square and at most 256 × 256 pixels.
What is a GIF file?
GIF is the original web animation format. Each frame can use only 256 colours, so it suits simple graphics and short loops rather than photos.
What sizes does the ICO file include?
The standard icon sizes of 16, 32, 48, 64, 128 and 256 pixels, skipping any larger than your image. Browsers and Windows pick the best size automatically.
Is the GIF to ICO converter free?
Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.

品質スライダーレンジ: 20–100 · デフォルト: 90
For JPG, WebP, AVIF and image-to-PDF output: higher keeps more detail but makes a bigger file; 60–80 suits most photos. Documents (Publisher, XPS, EPS…) become PDFs with every page and sharp text, with no quality setting.
ロスレスモードオン/オフ
For WebP and AVIF output: keeps every pixel exactly (best for logos, graphics and transparency) at the cost of a larger file.
背景の塗りつぶしカラーピッカー
For JPG, BMP and image-to-PDF output, which can’t store transparency: the colour that fills transparent areas (white by default).
