Quality & Fidelity
When converting from Photoshop Big to ICO Icon, the conversion is lossless, meaning every bit of data is preserved exactly as in the original. Photoshop Big retains all original data. Converting to ICO Icon adds no further quality degradation since it uses lossless compression. Xonvert selects parameters that maximize quality for the target format. For professional use, quality assurance is critical. Xonvert's Photoshop Big to ICO Icon pipeline has been tested against reference implementations to ensure output meets image industry standards.
