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 2022, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.
High-quality FLAC encoding
Transloadit offers a FLAC preset to easily encode audio files into FLAC.

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

compatible for all browsers.
":original": {
"robot": "/upload/handle"
}
/upload/handle Robot
This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically
2. Encode audio to FLAC
We offer a variety of features to reduce audio size while maintaining quality, as well as add effects like loops or watermarks. Learn more ›

}
/audio/encode Robot
This bot converts audio files into all kinds of formats for you. We provide encoding presets for the most common formats
3. Export files to Amazon S3
We export to the storage platform of your choice. Learn more ›
Once all files have been exported, we can ping a URL of your choice with the Assembly status JSON.

}
/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.

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
-
Pingbacks
Configure anotify_urlto let your server receive transcoding results JSON in thetransloaditPOST field.
