UPI to WEBPLL Conversion: FAQ

What are UPI files?

UPI is an image format associated with Ulead PhotoImpact, an advanced image editing program released in the 1990s and which had several subsequent releases until the 2000s. Ulead could handle both raster and vector files and was acquired by Corel in 2006. UPI functions as a plugin file that can be added to other software in order to support Ulead's own formats.
