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 2019, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.

Create a gzipped tar archive containing multiple result files

Using the bundle_steps functionality, the demo below will create one gzipped tar archive containing all the uploaded files and all /image/resize result files. Even if you upload multiple files, the result will be a single zip file.

}
/upload/handle Robot
This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programatically

2. Resize images to 100×100

We can resize, crop, and (auto-)rotate images, as well as watermark them. Learn more ›

This bot creates archives of files or file conversion results

4. Export files to Amazon S3

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

Once files are exported, we ping you back with the Assembly status JSON.

  "use": [
    "resized",
    "archived",
    ":original"
  ],
  "robot": "/s3/store",
  "credentials": "demo_s3_credentials"
}
/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.

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.
