charcraft64 is a lightweight and intuitive editor designed for the creation and modification of Commodore 64 character sets. The program allows to load character data from .prg or .bin files via the command line, the file menu or by dragging the files onto the application. Characters can be tested in a 25-row by 40-column screen editor that can load and save files in the file format of Marq's PETSCII editor. You can also drag a .c PETSCII file to open it in the editor.
