**GNU enscript**  컴퓨터 프로그램은  텍스트 파일을 pdf, PostScript, RTF,또는 HTML 형식등으로 변환하여주는 명령어형 프로그램이다. 변환시킬 대상파일 형식이 주어지지 않은 경우 입력 파일은 주어진 enscript 프로세스 표준으로 대체된다. Enscript는 명령어 형 프로그램이므로 파이프라인 등을 연계사용하여 확장할 수 있는 다른 형식의 출력이 미디어,텍스트 인코딩등  많은 옵션을 사용할 수 있는 사용자 정의 출력이 가능하다. 이것은 GNU GPL 버전 3하에 배포되고있다.

대용량 고속처리에도 불구하고 유니코드 등 완전한 인코딩은 미지원될수있다.
