Print work demands HD images — there's no getting around it. When clients send images that aren't HD quality, I used to have to ask for reshoots or new assets. Now I convert their images to HD with this tool first. The quality is good enough for most print applications, and the zero-watermark policy means the output is print-ready immediately.
