We are a Swiss Army knife for your files

Transloadit is a service for companies with developers. We handle file uploads and media processing for them. This way they can save on development-time and heavy machinery that’s 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’re still actively improving our service in 2017, as well as our open source projects uppy.io and tus.io, that are changing how the world does file uploading.

Encode video for browsers in 720p

There are different browsers from different vendors that try to push different video codecs. In this demo we generate a few different videos to ensure maximum compatibility with all browsers. We also generate a thumbnail that you can use as a poster

We can use WebM's VP9 codec for modern browsers and fall back to MP4s for the rest like so:

<video poster="thumbed.jpg">
  <source src="browser720_webm_encoded.webm" type="video/webm; codecs=vp9,vorbis">
  <source src="browser720_h264_encoded.mp4" type="video/mp4">
</video>
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. Receive files sent by users or apps

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

360s10f.mp4
34 MB · 22s · 1280 × 720

We handle uploads that your users throw at you from browser or apps, or that you throw at us programatically:

tl.addFile('file', './360s10f.mp4')

2. Resize videos to 1280 × 720 in WebM (VP9)

Transloadit offers a variety of features to reduce video size while maintaining quality, as well as add effects like watermarks. Learn more ›

  use: [':original'],
  robot: '/video/encode',
  height: 720,
  preset: 'webm',
  width: 1280,
}
/video/encode Robot
This bot encodes, resizes, applies watermarks to videos and animated GIFs

3. Resize videos to 1280 × 720 in iPad (high) (H.264)

  height: 720,
  preset: 'ipad-high',
  width: 1280,
}
/video/encode Robot
This bot encodes, resizes, applies watermarks to videos and animated GIFs

4. Extract thumbnails from videos

  count: 1,
  format: 'jpg',
  height: 720,
  resize_strategy: 'fit',
  width: 1280,
}
/video/thumbs Robot
This bot extracts any number of images from videos for use as previews

5. Export files to Amazon S3

Transloadit is happy to export to whatever storage solution suits you best. Learn more ›

exported: {
  use: ['browser720_webm_encoded','browser720_h264_encoded','thumbed',':original'],
  robot: '/s3/store',
  bucket: 'demos.transloadit.com',
  bucket_region: 'us-east-1',
  key: 'YOUR_AWS_KEY',
  secret: 'YOUR_AWS_SECRET',
}
/s3/store Robot
This bot exports encoding results to Amazon S3
Since this is a store robot, be sure to use Templates so that any credentials are encrypted and stored in our database, making sure that they’re never exposed to any end-user.

Try it yourself

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

Full code used

This demo uses :original, a magic word to identify uploads that Transloadit accepted.

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.
  • Backend 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.
