We are a Swiss Army knife for your files
Transloadit is a service for companies with developers. We handle file uploads and media processing for them. This way they can save on development-time and heavy machinery that’s 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’re still actively improving our service in 2018, as well as our open source projects uppy.io and tus.io, that are changing how the world does file uploading.
Implement HTTP Live Streaming (HLS)
The demo below encodes a video into three high-quality versions, before pushing them into the /video/adaptive Robot, which cuts them into several segments and generates playlist files containing all the segments.
The /video/adaptive Robot also generates an HLS master playlist file - a playlist of playlists, so to speak. Lastly, all the files are stored in your Amazon S3 bucket. The trick here is that all files are already stored in the proper location to make the playlist work. This is done using the special "${file.meta.relative_path}"
variable.
Our /video/adaptive Robot also supports MPEG-Dash. For more information about that, please check its documentation.
1. Receive files sent by users or apps
Transloadit can handle uploads of your users directly. Learn more ›
2. Transcode videos to HLS (270p) (H.264)
Transloadit offers a variety of features to reduce video size while maintaining quality, as well as add effects like watermarks. Learn more ›
3. Transcode videos to HLS (360p) (H.264)
4. Transcode videos to HLS (540p) (H.264)
5. Convert videos to HLS
Transloadit offers a variety of features to reduce video size while maintaining quality, as well as add effects like watermarks. Learn more ›

So many ways to integrate
-
Bulk imports
Add one of our import Robots to acquire and transcode massive media libraries. -
Handling uploads
We are the experts at reliably handling uploads. We wrote the protocol for it. -
Front-end integration
We integrate with web browsers via our next-gen file uploader Uppy and SDKs for Android and iOS. -
Backend integration
-
Pingbacks
Configure anotify_url
to let your server receive transcoding results JSON in thetransloadit
POST field.
