GIF to ICO Converter
You have a small GIF graphic and need an ICO for a favicon or a desktop shortcut. This page takes the GIF's first frame and builds an icon file with the sizes you choose, all on your own device. Animation is not used, and the file is never sent to a server.

WordPress and most site builders have a "Custom HTML" block where this code can be pasted. The embed keeps a small link back to CalcMaster.
How to convert GIF to ICO
- Add your GIF files by dropping them, clicking the drop zone or pasting.
- The output format is already set to ICO. Adjust quality or size if you need to.
- Press Convert and compare the original and new size for each file.
- Download each file or all of them as a ZIP.
When to convert, and when not to
- Your logo or mascot only exists as a GIF and you need favicon.ico.
- A shortcut or program requires an ICO file.
- You want to pack several icon sizes into one file.
- Do not expect an animated icon. ICO files made here hold still images only.
What changes
- Only the first frame is used.
- The ICO holds one PNG-compressed image for each size you tick, from 16 to 256 pixels. The default is 16, 32 and 48.
- The picture is fitted inside a square without stretching, and any unused space is transparent.
- Transparent GIF areas stay transparent, though soft edges were never part of the GIF.
- No metadata is carried over.
Turning a GIF graphic into an icon
Small GIF graphics are common for older logos and mascots. An icon, however, must be an ICO file for many places, such as a website favicon or a Windows shortcut. This converter bridges that gap by creating an ICO from the GIF's first frame.
You decide which sizes to include. Each size is made by scaling the frame to fit a square, then storing it inside the ICO file.
Once the ICO exists, you can check it in several places. Open it in a viewer that shows all contained sizes, add it as a site favicon on a test page, or assign it to a desktop shortcut. Each place uses a different size, so trying more than one tells you whether the artwork reads clearly everywhere.
Sharpness at small sizes
If the GIF is itself tiny, enlarging it for bigger icon sizes will look soft, because the pixels do not exist. Start with the largest version of the artwork you have, ideally a square image, and tick only the sizes that fit your needs.
The limited colour palette of GIF can also leave rough edges after scaling down. Simple, bold designs survive this much better than detailed ones.
To improve the look, recreate the graphic as a clean square image at a larger size if you can. Scaling a small GIF up cannot add detail, while scaling a large clean image down gives a crisp icon. This extra step is worth it for anything that represents your brand in a browser tab.
Where the finished icon goes
For a website, save the file as favicon.ico and point your pages to it. For a Windows shortcut, open the properties of the shortcut and choose the ICO as its icon.
Browsers cache site icons strongly, so a new icon may take a while to show. A private window is a quick way to check that the file works.
Documents about site setup often mention extra icon files for phones and tablets. The ICO from this page handles the classic favicon role. For the other roles, keep a square PNG of your artwork too, and use whichever file each platform asks for. The converter keeps your GIF on your device throughout.
Privacy: your files stay on your device
- The tool decodes, resizes and encodes your pictures with your browser. The files are never sent to a server.
- To check it yourself: open the browser developer tools (F12), open the Network tab, convert a file, and look for any request that carries your image. You will see none.
Frequently asked questions
Does the icon animate?
No. Only the first frame of the GIF is used.
Which sizes are available?
From 16 up to 256 pixels. The default is 16, 32 and 48.
Is a non-square GIF stretched?
No. It is fitted inside a square, and extra space is transparent.
Is the transparent background kept?
Yes, transparent areas stay transparent in each icon size.
Is my GIF uploaded?
No. The icon is built locally in your browser.
What should I do if my small GIF looks blurry as an icon?
Blurriness usually means the GIF has too few pixels for the size you ticked. Start from a larger, clean, square version of the artwork if you have one, and tick only the smaller sizes if the large one is all you have.
