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 2023, as well as our open source projects uppy.io and tus.io, which 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 docs.

⚠️ It seems your browser does not send the referer, which we need to stop people from (ab)using our demos in other websites. If you want to use the demos, please allow your browser to send its referer to us. Adding us to the allowlist of blockers usually helps.

🤖/s3/store
This bot exports encoding results to Amazon S3
Since this is a store Robot, be sure to use Template Credentials so that any sensitive data is encrypted and stored in our database, making sure that they’re never exposed to any end-user.

Live Demo. See for yourself

This live demo is powered by Uppy, our open source file uploader that you can also use without Transloadit, andtus, our open protocol for resumable file uploads that is making uploading more reliable across the world.

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.
