jQuery Example

By using our jQuery SDK, you can bring the power of Transloadit directly to your HTML forms. It will even display a stylish upload progress bar.

Enjoy ample customization options for design and behavior and make use of the many event callbacks to tailor its behavior to your needs.

We have a great new JavaScript uploader in the works called Uppy and you are welcome to give that a shot, but for now, the following example uses our jQuery SDK and it is still the recommended way to integrate Transloadit into web browsers.

  const uppy = Uppy.Core({ debug: true, autoProceed: false })

    .use(Uppy.Transloadit, {

      // use transloadit encoding result here.
      console.log('Result here ====>', stepName, result)
    })
    .run()
</script>

HTML5 Example

Uppy is our take on perfecting file uploading in the browser. It's rather new and not stable yet, but if you'd like to play around with it, you can already!

// npm install transloadit --save
const TransloaditClient = require('transloadit')

const transloadit = new TransloaditClient({
  authKey: 'YOUR_TRANSLOADIT_KEY',
  authSecret: 'YOUR_TRANSLOADIT_SECRET'
})

transloadit.addFile('myinput_1', './lolcat.jpg')

const options = {
  params: {
    steps: {
      thumb: {

    }
  }
}

transloadit.createAssembly(options, (err, result) => {
  if (err) {
    throw err
  }

Node.js Example

We have a fully featured software development kit for Node.js, so you can easily integrate it into your node apps.

// Install "transloadit/php-sdk"
// via Composer (https://getcomposer.org)
use transloadit\Transloadit;
$transloadit = new Transloadit(array(
  "key" => "YOUR_TRANSLOADIT_KEY",
  "secret" => "YOUR_TRANSLOADIT_SECRET",

PHP Example

Our PHP SDK allows you to automate the uploading of files through the Transloadit REST API using PHP.

It can be installed via composer.

Check out our PHP SDK integration

# gem install transloadit
transloadit = Transloadit.new(
  :key => "YOUR_TRANSLOADIT_KEY",
  :secret => "YOUR_TRANSLOADIT_SECRET"
)

thumb = transloadit.step "thumb", "/image/resize",
  :use => ":original",
  :result => true,
  :width => 75,
  :height => 75,
  :resize_strategy => "pad",
  :background => "#000000"
)

assembly = transloadit.assembly(
  :steps => [ thumb ]
)

files = []
files.push('./lolcat.jpg')

response = assembly.create! *files

until response.finished?
  sleep 1; response.reload!
end

if !response.error?
  # handle success
end

Ruby Example

Our Ruby Gem allows you to automate the uploading of files through the Transloadit REST API.

If you run Ruby on Rails and are instead looking to integrate with the browser to handle file uploads, then we also have a Ruby on Rails SDK ready for you to use.

Check out our Ruby SDK integration

# pip install pytransloadit
from transloadit import client

tl = client.Transloadit('YOUR_TRANSLOADIT_KEY', 'YOUR_TRANSLOADIT_SECRET')
assembly = tl.new_assembly()

# Add files to upload
assembly.add_file(open('./lolcat.jpg', 'rb'))

# Add instructions, e.g. resize image, or encode video
assembly.add_step('thumb', {
  'use': ':original',
  'robot': '/image/resize',
  'result': true,
  'width': 75,
  'height': 75,
  'resize_strategy': 'pad',
  'background': '#000000'
})

# Start the Assembly
assembly_response = assembly.create(retries=5, wait=True)

print assembly_response.data.get('assembly_id')

# or
print assembly_response.data['assembly_id']

options.AuthSecret = "YOUR_TRANSLOADIT_SECRET"

// Initialize new assembly

// Add files to upload

// Add instructions, e.g. resize image, or encode video

// Start the Assembly
info, err := client.StartAssembly(context.Background(), assembly)
if err != nil {
  panic(err)
}

// All files have now been uploaded and the assembly has started but no
// results are available yet since the conversion has not finished.
// WaitForAssembly provides functionality for polling until the assembly
// has ended.
info, err = client.WaitForAssembly(context.Background(), info)
if err != nil {
  panic(err)
}

fmt.Printf("You can view the result at: %s\n", info.Results["resize"][0].SSLURL)

npm install transloadify -g

echo '{
  "thumb": {
    "use": ":original",
    "robot": "/image/resize",
    "result": true,
    "width": 75,

export TRANSLOADIT_SECRET="YOUR_TRANSLOADIT_SECRET"

transloadify \
  --input ./lolcat.jpg \
  --output ./resized-lolcat.jpg \
  --steps ./steps.json

CLI Example

Don't feel like coding? Use our command line tool to watch an ./input/ directory for incoming files and automatically convert them through instructions that you saved locally in: ./steps.json.

The results will be saved in the ./output/ directory.

You can optionally automatically remove successfully processed input files.

Cropping Images

This demo resizes and crops uploaded images to 100x100 pixels. Drop files to the left, or select files using the device's native file browser. See the Demos page for the Assembly Instructions used.

Zip Archive

Transloadit can assemble multiple files into a single result, or a single file into multiple results. This demo archives all uploaded files into a single .zip file. See the Demos page for the Assembly Instructions used.

Face Recognition

With the Uppy Transloadit integration, users can upload photos from their webcam straight to Transloadit. Excellent for capturing profile pictures! See the Demos page for the Assembly Instructions used.

Virus Scanning

Scan uploaded files and reject virus-infected ones before they ever reach your servers. See the Demos page for the Assembly Instructions used.

Image optimization

Save bandwidth and storage space by losslessly optimizing images, reducing file sizes by up to 80%. See the Demos page for the Assembly Instructions used.
