AV Preservation by reto.ch

Please note that currently we telework as much as possible, and the easiest way to reach us is by email.


We are a small, highly skilled moving image conservation and restoration facility based in Switzerland. Our team provides worldwide comprehensive services that encompass the whole range of audio-visual preservation, offering Swiss quality at a competitive price. We have a particular commitment to the dissemination of audio-visual conservation and restoration techniques, and we support open-source projects which we believe are beneficial for the archival community. We are actively engaged in a number of relevant national and international professional bodies.

From Analogue to Digital

At the end of 2012, after eight years of activity, the old company reto.ch Sàrl has been closed. A new company AV Preservation by reto.ch Sàrl has opened at the beginning of 2013 at the same address with the same staff and an improved digital offer, yet without the analogue lab. Two years later we moved one kilometre to the north-east. And in 2020 we moved four kilometres to south-west, from Écublens to Préverenges.
