Integrates well with these platforms

Apart from these integrations, there are many community projects.

Easy Integration

$(function() {
    params: {
      auth: {
        key: 'abc123'

      steps: {
        resize_to_125: {
          robot           : '/image/resize',
          use             : ':original',
          width           : 125,
          height          : 125,
          resize_strategy : 'pad',
          background      : '#444'

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.

Check out our jQuery SDK

var TransloaditClient = require('transloadit');
var transloadit       = new TransloaditClient({
  authKey    : 'abc123',
  authSecret : 'abc123efg'

transloadit.addFile('myimage', './lolcat.jpg');

var options = {
  params: {
    template_id: 'xyz789'
transloadit.createAssembly(options, function(err, result) {
  if (err) {
    throw new Error(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.

On the left side, you can see how easy it is to execute a Template of encoding instructions (saved on the website) on a set of local files.

Check out our Node.js SDK

options := transloadit.DefaultConfig
options.AuthKey = "abc123"
options.AuthSecret = "abc123efg"
client, err := transloadit.NewClient(options)
if err != nil {

assembly := client.CreateAssembly()
assembly.AddFile("myimage", "./lolcat.jpg")
assembly.AddStep("resize_to_125", map[string]interface{}{
    "robot": "/image/resize",
    "width": 125,
    "height": 125,

info, err := assembly.Upload()
if err != nil {

Go Example

We have a powerful Go client that makes using Transloadit easy.

On the left side, you can see an example of executing a dynamic file conversion Step on a local file.

Our Go SDK also ships with transloadify, which bundles much of the technology inside this SDK as a command line utility. Please check the "Command-line" tab for an example of this.

Check out our Go SDK

transloadit =
  :key    => 'abc123',
  :secret => 'abc123efg'
resize_to_125 = transloadit.step 'resize_to_125', '/image/resize',
  :width  => 125,
  :height => 125

assembly = transloadit.assembly(
  :steps => [ resize_to_125 ]

response = assembly.submit! open('./lolcat.jpg')
until response.finished?
  sleep 1; response.reload!

if !response.error?
 # handle success

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

use transloadit\Transloadit;
$transloadit = new Transloadit(array(
  'key'    => 'abc123',
  'secret' => 'abc123efg',

$response = $transloadit->createAssembly(array(
  'files' => array(
  'params' => array(
    'steps' => array(
      'resize_to_125' => array(
        'robot'  => '/image/resize',
        'width'  => 125,
        'height' => 125,

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

mkdir "./templates/"
mkdir "./input/"
mkdir "./output/"

curl "" \
  -Lo "./transloadify"
curl "" \
  -Lo "./templates/hls.json"
curl "" \
  -Lo "./input/sample_mpeg4.mp4"

chmod 755 ./transloadify
export TRANSLOADIT_KEY="abc123"
export TRANSLOADIT_SECRET="abc123efg"

./transloadify \
  -input="./input/" \
  -output="./output/" \
  -template-file="./templates/hls.json" \

Command-line 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 in a locally saved Template: ./templates/hls.json.

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