TIFF to ICO Converter — Free Favicon & Icon Maker in Your Browser

Icons power favicons, app shortcuts, and desktop files — and the .ico format is still the one Windows expects. Drop in a TIFF, pick an icon size, and get a real .ico file built in your browser. One plain fact about the output: the icon is a PNG image embedded inside a standard ICO container. That is a valid .ico, and it works in modern Windows (Vista and later), browsers, and icon tools — but very old software that only understands BMP-based icons will not read it. Everything runs in your browser; your files never leave your device.

How it works

• Step 1 — Drop in your .tif / .tiff files, one or a batch.
• Step 2 — Pick an icon size (16, 32, 48, or 256 px) and whether to keep transparency. Non-square images are center-cropped to a square first.
• Step 3 — Hit Convert to ICO. Each TIFF is decoded in your browser (UTIF.js loads on first use), resized to a square canvas, encoded as PNG, and wrapped in a standard ICO container with its own download button.
• Private by design — everything runs locally in your browser; your files never leave your browser.

Everyday uses

• Favicons — make a favicon.ico from a logo scan or artwork.
• Desktop shortcuts — give folders and apps custom icons on Windows.
• App icons — produce quick .ico builds during development.
• Brand kits — convert one source image into every standard icon size.
• Retro projects — turn old scans into icons for classic-style desktops.

Plain note on compatibility: the .ico files here embed a PNG image, which is the modern standard and works in Windows Vista and later, all major browsers, and icon editors. Software from before ~2007 that expects BMP-based icons may not open them.
