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.
Implement MPEG-Dash using Transloadit
The demo below encodes a video file into two high-quality, video-only versions as well as into two high-quality, audio-only versions in order to prepare the video file for use with MPEG-Dash.
The demo then pushes all these result files into 🤖/video/adaptive,
which cuts them into several segments, before generating the MPEG-Dash segments and the manifest
file. 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 sure that the manifest file works. This is done
using the special "${file.meta.relative_path}" variable.
🤖/video/adaptive also supports HTTP Live Streaming (HLS). For more information about that, please check its docs.

Loading Uppy demo…
This live demo is powered by 
Uppy, our open source file uploader that you can also use without Transloadit, and 
tus, our open protocol for resumable file uploads that is making uploading more reliable across the world.
Build this in your own language
<!-- This pulls Uppy from our CDN -->
<!-- For smaller self-hosted bundles, install Uppy and plugins manually: -->
<!-- npm i --save @uppy/core @uppy/dashboard @uppy/remote-sources @uppy/transloadit ... -->

So many ways to integrate
Transloadit is a service for companies with developers. And there are many ways developers can put Transloadit to good use inside your company to automate media processing.
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.
Back-end integration
Send us batch jobs in any server language using one of our SDKs or directly interfacing with our REST API.
Pingbacks
Configure a notify_url to let your server receive transcoding results JSON in the transloadit POST field.
On-demand
Use our Smart CDN to adapt files on-demand and stream them directly to your users.
Video encoding
