Krieps was born in Hesperange, the daughter of a Luxembourgish father, who managed a film distribution company, and German mother. Her father, Bob Krieps, is the director general of the Ministry of Culture of Luxembourg, the former director of Sacem Luxembourg, and the former president of the Luxembourg Film Fund. Several of her films have been funded by the Luxembourg Film Fund, which is supervised by the Ministry of Culture, which then decides which films will be funded by state subsidies. Her paternal grandfather, Robert Krieps, was a politician, war-time member of the Luxembourg Resistance, and Luxembourg's Minister of Justice, National Education and Culture in the 1970s and 1980s.

Krieps had her first acting experiences at the Lycée de Garçons secondary school in Luxembourg City, receiving training at the Conservatoire de Luxembourg.[citation needed] Rather than enrolling in one of the drama schools, she participated in a social project at the primary school of a South African township near Knysna. This confirmed her resolve to study acting, with the goal of performing on theatre stages.

Krieps attended Zurich University of the Arts, while gathering acting experience at Schauspielhaus Zürich.
