A wireline release tool may include a casing configured to couple to a wireline and a connector configured to couple to a tool string. The casing may have a first end, a second end, and a chamber therebetween, and the connector may be detachably attached to the second end of the casing. A gas generator may be disposed in the chamber and may be capable of generating gas pressure in the chamber sufficient to overcome a pressure differential between the chamber and the external wellbore environment and to detach the connector from the casing.
