Frequently Asked Questions

Can I use the converted ICO as a website favicon?

Yes. The output ICO file is a standard favicon-compatible format. Place it at your site root as favicon.ico or reference it with a link tag in your HTML head.

Does the conversion upload my TIFF to a server?

No. ChangeThisFile converts TIFF to ICO entirely in your browser using the canvas API. Your file never leaves your device.

What size will the ICO file be?

The converter produces an ICO file at the source image dimensions. For optimal favicons, start with a square TIFF image at 256x256 or 512x512 pixels.

Does ICO support transparency?

Yes. ICO files support full alpha channel transparency (32-bit), so transparent areas in your TIFF will be preserved correctly in the output.

Can I create multi-size ICO files with multiple resolutions?

The current converter outputs a single-resolution ICO frame. For production favicons with multiple embedded sizes, you may want to use a dedicated icon editor after initial conversion.

What TIFF file size is best for making icons?

For icons and favicons, a square TIFF with dimensions between 64x64 and 512x512 pixels works best. Very large TIFFs will be scaled down but convert fine.

Is the TIFF to ICO converter free?

Yes. ChangeThisFile is completely free with no conversion limits, no watermarks added, and no account required.

Which browsers recognize ICO favicons?

All major browsers — Chrome, Firefox, Safari, and Edge — recognize ICO favicons. It remains the most broadly supported favicon format.

Can I convert a colored TIFF logo to ICO?

Yes. Full-color TIFF images convert to ICO retaining all colors. The ICO format supports 24-bit and 32-bit color with alpha transparency.
