AV Preservation by reto.ch

Please note that we still telework as much as possible. Email is the fastest and most effective way to reach us.


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. We are running the Swiss Film and Video Directory.

We are always closed on יום הכיפורים (Yom Kippur). Next time on the 4th and 5th of October 2022.

Our website does not use tracking because we believe the visitors are human beings and not commodities.

The Move 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 film lab. Two years later we moved one kilometre to the north-east. At the beginning of 2020 we have closed the analogue video department and moved four kilometres to south-west, from Écublens to Préverenges. And from March 2023, our conservation and restoration workshop will partly operate at the Lichtspiel in Bern.
