The online file converter that used to be available from convert.goldensoftware.com has been retired. All of the conversions that could be performed from the converter can also be performed from within Surfer (full version or free trial), except for the old file conversions. If you have an old Surfer or Grapher file that you need converted, see the below resources:

• Can You Convert My Old Grapher Files?
• Can You Convert My Old Surfer Files To Open In Newer Versions Of Surfer?
