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.

1. Handle uploads

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

':original': {
  robot: '/upload/handle',
}

/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 ›

resized: {
  use: [':original'],
  robot: '/image/resize',
  height: 100,
  width: 100,
  zoom: false,
}

/image/resize Robot

This bot resizes, crops, changes colorization, rotation, and applies text and watermarks to images

3. Compress files

We can both archive and extract entire media libraries. Learn more ›

archived: {
  use: {'steps':[':original','resized'],'bundle_steps':true},
  robot: '/file/compress',
  format: 'tar',
  gzip: true,
}

/file/compress Robot

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 ›

:original

resized

archived

s3.amazonaws.com/demos.transloadit.com/ab/973320590d11e895e3b9b3f260a889/ben-o-sullivan-382817.tgz

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

exported: {
  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.

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.
