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.

Automatically decompress uploaded archives

Perhaps you would like your users to upload any file and, if it is an archive, automatically extract it first.

As documented on our formats page, there are many different archive mime-types that Transloadit can extract. In this demo, we will show you how to filter archives, extract them first, and then pass the extracted files through normal encoding steps (converting to optimized for iPad and webm formats in this case).

Finally, we export both the original files and the encoded videos to an S3 bucket.

⚠️ 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.

Step 1: Handle uploads

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

⚠️ It seems your browser does not support the codec used in this video of the page. 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.

":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: Pick archives

We let you reject, or direct files against different encoding Steps. Learn more ›

Step 4: Transcode videos to iPad (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 ›

Step 6: Export files to Amazon S3

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

:original

web_encoded

Once all files have been exported, we can ping a URL of your choice with the Assembly status JSON. 

"exported": {

  "credentials": "YOUR_AWS_CREDENTIALS",
  "url_prefix": "https://demos.transloadit.com/"
}
🤖/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.
