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.

Import a specific file from S3

Our /s3/import Robot allows you to import specific files from your Amazon S3 account with very easy syntax. After the processing is done, you can see the file that was imported in the result JSON at the bottom.

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. Import files from Amazon S3

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

imported: {
  robot: '/s3/import',
  bucket: 'demos.transloadit.com',
  bucket_region: 'us-east-1',
  key: 'YOUR_AWS_KEY',
  path: 'my_folder/snowflake.jpg',
  secret: 'YOUR_AWS_SECRET',
}
/s3/import Robot
This bot imports whole directories of files from your S3 bucket

2. Resize images to 130 × 130

Transloadit can resize, crop, and (auto-)rotate images, as well as watermark them or read & write meta-data. Learn more ›

resized: {
  use: ['imported'],
  robot: '/image/resize',
  height: 130,
  width: 130,
  zoom: false,
}
/image/resize Robot
This bot resizes, crops, changes colorization, rotation, and applies text and watermarks to images

3. Export files to Amazon S3

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

exported: {
  use: ['imported','resized'],
  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 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.
  • 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.

Try it in your account
