The 30-year-old's new deal at the Priestfield Stadium is due to expire at the end of the 2015-16 campaign.
Kedwell, who would have been a free agent this summer, scored 10 goals during the first half of last season before spending three months on the sidelines through injury.
The forward joined the Gills from AFC Wimbledon in 2011.
