Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert TIFF raster images to ICO icon format instantly with ConvertX. This conversion is essential for developers and designers creating application icons and favicons.
TIFF is a flexible, high-resolution raster format primarily used in professional photography and publishing, whereas ICO is a specialized raster format designed specifically for Microsoft Windows icons and browser favicons, supporting multiple resolutions in a single file. Converting TIFF to ICO packages your detailed graphic into a structure optimized for operating system interfaces and shortcuts.
Since both TIFF and ICO are raster formats, the conversion happens without quality loss, preserving your image clarity entirely. The file size changes insignificantly during the process.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
