openCanvas is a raster graphics software developed and published by PGN Corp. It was originally released as freeware in 2000,^[2] but moved to a shareware model starting with version 2.^[3] All functions are available during the limited demo period. A higher performance version "openCanvas Plus" has been released simultaneously since version 3. Its functions are similar to Adobe Photoshop or Corel Painter.

In 2009, portalgraphics.net ended the sales of the openCanvas English versions. At the same time, they ended the English version of the portalgraphics website and their online English Customer Services, including PGN User Community. English Customer Support was to be discontinued on July 31, 2010. However, the English portalgraphics website went active again shortly afterward, and portalgraphics has continued sales of openCanvas series to the present.

"openCanvas 5.5.18" was released on July 26, 2013 in Japanese and English.^[4] On July 3, 2014, "openCanvas 6.0.00" was released with 64-bit support.^{[citation needed]}
