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.

Segment video files and create a playlist

Note: This Robot is no longer the recommended way to generate HLS segments. Please use 🤖/video/adaptive instead.

🤖/media/playlist Robot generates playlist files for HTTP Live Streaming (HLS).

This Robot accepts HLS segments generated by 🤖/audio/encode and 🤖/video/encode. You need to pass an 🤖/audio/encode or 🤖/video/encode Step that had its segment parameter set to true, to the use parameter of this Robot.

All segments need to be passed to the Robot at the same time, and not one by one. That is why you must use the bundle_steps parameter, otherwise you will generate multiple playlist files that each contain only one segment.

Also, please make sure that you export your segments (to Amazon S3 for example). If you do not, your playlist file will become invalid after 24 hours, when we remove temporary result files.

Step 1: Handle uploads

We can handle uploads of your users directly. Learn more ›

":original": {
  "robot": "/upload/handle"
}
🤖/upload/handle
This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically

Step 2: Resize videos to 800×600 and encode for iPhone (high quality) (H.264)

We offer a variety of video encoding features like optimizing for different devices, merging, injecting ads, changing audio tracks, or adding company logos. Learn more ›

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.
