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 2024, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.

Make video compatible for all devices

If you have users on many different devices, and you want to offer them the optimal experience, you want to deliver the smallest files possible, so you want to make sure that you're not shipping:

  1. pixels beyond what their screen can render
  2. quality beyond what their bandwidth can carry
  3. codecs that their device can't understand (an obvious prerequisite)

MPEG-DASH is a great new standard that can adjust video quality for users, while it is playing. This means that quality can be scaled all the way down to audio-only as users move through tunnels, and pick back up to full HD (or more) when they're on Wi-Fi.

Native support for MPEG-DASH across browsers in 2018 is lacking. Luckily there is dash.js, a JavaScript library that can add MPEG-DASH support to browsers that support Media Source Extensions. As you can see, in early 2018 that means iOS is out of the window. Sad.

Before MPEG-DASH was conceived, Apple already had this Adaptive technology as a proprietary undertaking, called HLS. So if you'd want to offer the best experience, ideally you make the player switch between HLS and MPEG-DASH, so long as Apple isn't on board yet. And then maybe you want to add 'old school' mp4 and webm files, just for devices or players that aren't (in) browsers and won't support Adaptive streaming for some time to come.

In this, admittedly, rather long example, we're going to illustrate how to generate all these different formats, along with a code snippet of how your player could switch between those.

We can use WebM's VP9 codec for modern browsers and fall back to MP4s for the rest like so:

So many ways to integrate

Transloadit is a service for companies with developers. As a developer, there are many ways you can put us to good use.

  • 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.
