Free online TIF to ICO converter

Windows applications and desktop shortcuts may require an .ico file, while a scanner or publishing workflow commonly produces TIFF. Converting the image creates an icon that can contain several sizes and display correctly at different resolutions.

What the TIF format is

TIFF (Tagged Image File Format), identified by .tif or .tiff, is a raster format used for scanned documents, photographs, print production, maps, and archival images. It supports lossless compression, high bit depths, color profiles, transparency, and multipage files.

Scanners, document-management systems, Photoshop, GIMP, Affinity Photo, and other graphics applications create or export TIFF files. TIFF prioritizes image fidelity rather than icon compatibility, so its dimensions, color mode, file size, or multipage structure may need adjustment before conversion.

What the ICO format is

ICO is a Windows icon container used for application executables, folders, shortcuts, and other interface items. One file can contain multiple raster images, commonly at 16×16, 24×24, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. Windows selects a suitable embedded size instead of scaling one image for every use.

ICO supports transparency and can store larger images with PNG compression. Renaming .tif to .ico does not convert the file; the image must be encoded in the ICO container.

Convert the file on 101convert.com

1. Open the TIF-to-ICO converter on 101convert.com.
2. Upload the .tif or .tiff file.
3. Choose ICO as the output format and start the conversion.
4. Download the resulting .ico file and test it as a shortcut or application icon.

The conversion is free and does not require installing software. For sensitive documents, use a local application instead of uploading the source.

Convert with ImageMagick

ImageMagick is suitable for repeatable conversions and batch processing. After installing it, run this command in the directory containing the TIFF:

magick input.tif -define icon:auto-resize=16,24,32,48,64,128,256 output.ico

Replace the input and output filenames as required. For a multipage TIFF, select one page explicitly, usually the first:

magick "input.tif[0]" -define icon:auto-resize=16,24,32,48,64,128,256 output.ico

To preserve an existing alpha channel and avoid adding an opaque background, use:

magick input.tif -alpha on -background none -define icon:auto-resize=16,24,32,48,64,128,256 output.ico

For a single square 256-pixel icon, crop or pad without distorting the image:

magick input.tif -resize 256x256^ -gravity center -extent 256x256 -background none output.ico

The ^ modifier scales the image until both dimensions cover the square; -extent then crops the excess. Use transparent padding instead when cropping would remove important content.

Convert with an image editor

GIMP and IrfanView can open TIFF and export ICO. In GIMP, open the source, make the canvas square with transparent padding or crop it, and use Image → Scale Image to prepare an icon-sized image. Then choose File → Export As, enter a filename ending in .ico, and select the available icon or compression options.

IrfanView users can open the TIFF and choose File → Save As, then select ICO - Windows Icon. Its export options and batch tools are useful for fixed-size or repeated conversions. Editors differ in whether they write one image or a multi-size ICO, so inspect the exported file before deployment.

Quality and compatibility limits

• Start with a square image or add transparent padding. Stretching a wide or tall TIFF into a square distorts its content.
• Include several embedded sizes for Windows icons. A single 256×256 image may be scaled poorly for small shortcuts.
• Simplify photographs, thin lines, and small text before reducing them to 16×16 or 32×32; fine detail disappears at those sizes.
• TIFF files using CMYK, unusual bit depths, layers, or multiple pages may be converted to a flattened, RGB image, and only one page is normally appropriate for an icon.
• Transparency may be lost if the converter composites the image against a background. Check edges and transparent areas after export.
• Some older Windows or third-party programs accept only limited dimensions, color depths, or uncompressed icon images. Test the ICO in the target program, shortcut, or icon viewer.
