GIF to ICO converter: free, fast and secure
Need to change an image from GIF to ICO? This tool does it instantly and for free, without uploading your pictures anywhere. GIF is limited to 256 colours.

What is GIF?
GIF is one of the oldest image formats on the web, dating back to 1987. It is limited to 256 colours per frame, which is fine for simple graphics and memes but causes visible banding in photos. GIF supports basic on/off transparency and animation, and it opens everywhere, from old browsers to chat apps.
What is ICO?
ICO is the icon format used for website favicons and Windows icons. One .ico file can contain several sizes of the same picture (16, 32, 48 up to 256 pixels) so the system can pick the right one for tabs, bookmarks, the taskbar or the desktop.
When should you convert GIF to ICO?
- Website favicons for the browser tab
- Windows app and shortcut icons
- Folder icons
- Bookmarks and pinned sites
Tips for the best ICO results
- Use a square logo of at least 256×256 pixels with a transparent background. For a full favicon package with Apple and Android icons, use the Favicon Generator.
- You can convert many GIF files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original GIF files until you have checked the converted ICO images.
How GIF to ICO keeps your photos and images private
Most online converters upload your file to their server, process it there and send it back. That costs time, uses your data pack and means a copy of your file sits on someone else’s computer. GIF to ICO works differently: the page loads the tool into your browser, and your photos and images are processed by your own phone or computer. The file never travels over the internet, so it cannot be leaked, stored or misused.
Using GIF to ICO on your phone
GIF to ICO is designed for small screens. Buttons are large, options are simple, and downloads save directly to your phone storage. On iPhone, downloaded files appear in the Files app under Downloads; on Android they go to the Downloads folder.
Who uses GIF to ICO?
You do not need any technical knowledge to use it. It is popular with:
- Students uploading photos and signatures to exam and admission forms
- Online sellers preparing product photos for Instagram, Meesho, Amazon and Shopify
- Office staff handling ID cards, scans and screenshots
- Bloggers and web designers who need fast-loading images
- Anyone sharing pictures on WhatsApp, email or social media
Supported input: JPG, JPEG, PNG, WEBP, HEIC/HEIF (iPhone), AVIF, GIF, BMP, TIFF and SVG.
