We are a Swiss Army knife for your files

Transloadit is a service for companies with developers. We handle their file uploads and media processing. This means that they can save on development time and the heavy machinery that is required to handle big volumes in an automated way.

We pioneered with this concept in 2009 and have made our customers happy ever since. We are still actively improving our service in 2026, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.
