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

This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically

2. Resize images to 100×100

We can resize, crop, and (auto-)rotate images, or apply watermarks and other effects, and much more. Learn more ›

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

  ],

}

🤖/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.
