TIFF to ICO Converter

What TIFF to ICO conversion does

Convert a TIFF image into a Windows ICO icon directly in your browser. Generate a single size, or the default multi-size package covering 16, 32, 48, 64, 128, and 256 px, built from the first page of the source TIFF.

How to convert TIFF to ICO

1. Choose a TIFF or TIF file.
2. Pick a single icon size, or leave the default multi-size package selected.
3. Select Convert & download.
4. Save the .ico file from your browser downloads.

Why use this conversion

ICO is what Windows expects for application icons, desktop shortcuts, and favicons. Turning the first page of a scanned or archival TIFF into an icon set is a somewhat unusual pairing, but a real one — for example, using a document's cover page as a recognizable thumbnail-style icon.

Transparency and output quality

Each embedded size keeps the alpha channel from the source TIFF page, if it has one (TIFF can carry alpha via its ExtraSamples tag) — this is a real ICO container (ICONDIR plus one entry per size), with each size embedded as genuine PNG-compressed image data, not a renamed bitmap. Each icon entry uses PNG compression, so a single-size ICO built from one TIFF page stays small; the multi-size package is larger since it bundles six images.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: TIFF (.tif, .tiff) only, up to 25.0 MB and 8,192 px per side.
• Each icon size is generated by resizing the full image to a square canvas, so a non-square TIFF page — common for scanned documents — will be stretched to fit.
• When the source TIFF has multiple pages, the icon set is built from page one alone — any further pages are dropped before the ICO is generated.
• Metadata is not preserved in the downloaded file.

TIFF to ICO FAQ

Why convert TIFF to ICO?

ICO is what Windows expects for icons and favicons. Converting turns the first page of a TIFF — often a scan or archival image never designed to be an icon — into a real, multi-resolution .ico file, such as using a document's cover page as a thumbnail-style icon.

Can I generate a multi-size ICO?

Yes. The ICO output defaults to a multi-size package covering 16, 32, 48, 64, 128, and 256 px, built from the first page of the TIFF, or you can pick a single size from the dropdown.

Is this a real ICO file, or a renamed image?

A real ICO container (ICONDIR plus one entry per size), with each size embedded as genuine PNG-compressed image data — and the alpha channel from the source TIFF page is preserved if it had one.

Does this convert every page of a multi-page TIFF?

No. If the source TIFF has more than one page, only the first is turned into the icon set — subsequent pages are ignored entirely.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a TIFF — the tool checks the byte-order header (little-endian "II*" or big-endian "MM*"), not just the filename or extension, before decoding.
