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 2020, 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 our /video/adaptive Robot instead.

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

This Robot accepts HLS segments generated by the /audio/encode and /video/encode Robots. 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.

Warning 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 whitelist of blockers usually helps.

1. 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 ›

Warning It seems your browser does not support the codec used in this video of the demo. For demo simplicity we'll link you to the original file, but you may also want to learn how to make videos compatible for all browsers.

/video/encode Robot
This bot encodes, resizes, applies watermarks to videos and animated GIFs

2. Export files to Amazon S3

We export to the storage platform of your choice. Learn more ›

/s3/store Robot
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.

3. Generate media playlists

We can enrich media files with metadata and generate playlists for them. Learn more ›

Live Demo. See for yourself

This particular demo does not rely on file uploads and is therefore typically not initiated from web browsers. However, just so you can get a feeling for our service, we’re happy to let you run this right here regardless.

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.
