Technical Quality Assessment
Color accuracy is a priority in this conversion. Color profiles (sRGB, Adobe RGB, etc.) are preserved when both formats support them. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. Photoshop Big preserves all data losslessly, so output size depends on the content's inherent compressibility. Use PSB when your file exceeds PSD dimension or size limits For the best results, start with the highest quality Keynote Presentation source file available.
This is a cross-category conversion from Document (Keynote Presentation) to Image (Photoshop Big).
