    Encoding platforms require ongoing investment to deal with encoding, scaling, and stack headaches. We let you free up development & server capacity.

  • Automate your media workflows

    Combine 61 features (Robots) to create workflows unique to your business. An elegant declarative JSON language makes this fool- and bullet proof.

  • Globally distributed, uptime 99.99%

    Globally distributed, highly available, and scales to match any traffic. For 12 years in a row, that has paid off in an uptime of > 99.99%. See Server Status

Having a solution for both uploading and transcoding has been a godsend for the current scale that we are at five years after first choosing Transloadit.

There’s more...

Detect malicious files
Our file filtering service guarantees that each file finds its way into the appropriate encoding pipeline, and offers you protection against the many dangers of the digital world. Millions of trojans, viruses, malware, and other malicious threats are eliminated before they even reach your platform.
Automate your processing with AI
Transloadit offers Artificial Intelligence as a service, so you don't have to run your own models or install complicated software. Benefit from various AI capabilities that are available right inside our encoding pipelines to further automate your media processing.
Smart CDN
A Content Delivery Network (CDN) is the best place to host content. Files are cached and distributed globally in order to keep latencies low. Transloadit can make sure that content is delivered from a data center close to you or your user, wherever in the world that may be.
Compress files and save data
With encoding jobs potentially involving large amounts of input files, file compression can be instrumental for keeping data usage under control. Transloadit is able to archive and extract entire media libraries, and supports a wide variety of compression algorithms and formats.

Import and export to any of these services

Easy integration

Platforms

There's more...

Apart from these, there are integrations for Android, HTML2, Rails, Heroku, Zapier, Terraform, and many community projects

RestAPI

Instead of sending Assembly Instructions directly to Transloadit, you can also save them in a secured way as a Template. You can then refer to the template_id in your requests, making sure that secrets and Instructions no longer have to be transmitted, which is a security risk in many cases.

Here is a 'raw' Template, in case you would like to save these Instructions safely in your account, or use these Instructions to talk directly to our REST API without using any SDK.

{
  "thumb": {
    "use": ":original",
    "robot": "/image/resize",
    "width": 75,
    "height": 75,
    "resize_strategy": "fit"
  }
}

cURL

Read docs: cURL

We would not recommend to use the cURL integration for production, but it can be convenient for a quick test when you don't have an SDK lying around.

# Prerequisites: brew install curl jq || sudo apt install curl jq
# To avoid tampering, use Signature Authentication
echo '{
  "auth": {
    "key": "YOUR_TRANSLOADIT_KEY"
  },
  "steps": {
    "thumb": {
      "use": ":original",
      "robot": "/image/resize",
      "width": 75,
      "height": 75,
      "resize_strategy": "fit"
    }

iOS & macOS

Read docs: TransloaditKit

It's easy to start using Transloadit in Objective-C and Swift using CocoaPods or Carthage and leverage file uploading & encoding in macOS and iOS apps.

// Add 'Transloadit' to your Podfile, run 'pod install', add credentials to 'Info.plist'
import Arcane
import TransloaditKit

// Set Encoding Instructions
var AssemblySteps: Array = Array<Step>() // An array to hold the Steps

var Step1 = Step (key: "thumb") // Create a Step object
Step1?.setValue(":original", forOption: "use") // Add the details
Step1?.setValue("/image/resize", forOption: "robot") // Add the details
Step1?.setValue(75, forOption: "width") // Add the details
Step1?.setValue(75, forOption: "height") // Add the details
Step1?.setValue("fit", forOption: "resize_strategy") // Add the details
AssemblySteps.append(Step1) // Add the Step to the array

// We then create an Assembly Object with the Steps and files
var MyAssembly: Assembly = Assembly(steps: AssemblySteps, andNumberOfFiles: 1)

// Add files to upload
MyAssembly.addFile("./chameleon.jpg")

// Start the Assembly
Transloadit.createAssembly(MyAssembly) 

// Fires after your Assembly has completed
transloadit.assemblyStatusBlock = {(_ completionDictionary: [AnyHashable: Any]) -> Void in
  print("\(completionDictionary.description)")
}

jQuery

Read docs: jQuery SDK

Until Uppy reached 1.0, our jQuery SDK was the recommended way to integrate Transloadit with web browsers. This is no longer the case and we'd now like everybody to use Uppy instead. The form method of the Robodog Plugin offers a very easy migration for jQuery SDK users.

<body>
  <form action="/uploads" enctype="multipart/form-data" method="POST">
    <input type="file" name="my_file" multiple="multiple" />

          key: 'YOUR_TRANSLOADIT_KEY',
        },
        // It's often better store encoding instructions in your account
        // and use a `template_id` instead of adding these steps inline
        steps: {
          thumb: {
            use: ':original',
            robot: '/image/resize',
            width: 75,
            height: 75,
            resize_strategy: 'fit'
          }
        }
      }
    });
  });
  </script>

HTML5

Read docs: Uppy File Uploader

Uppy is an open source file uploader for web browsers by Transloadit. With over 24,000 stargazers on GitHub it is the #1 file uploader in the world. Uploads can survive network hiccups, browser crashes, and accidental navigate-aways thanks to Tus support built-in, and it is the recommended way to integrate Transloadit with web browsers.

// yarn add transloadit || npm i transloadit --save-exact
const Transloadit = require('transloadit')

const transloadit = new Transloadit({
  authKey: 'YOUR_TRANSLOADIT_KEY',

CLI

Read docs: Transloadify

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.

[sudo] npm install transloadify -g

export TRANSLOADIT_KEY="YOUR_TRANSLOADIT_KEY"
export TRANSLOADIT_SECRET="YOUR_TRANSLOADIT_SECRET"

# Save Encoding Instructions
echo '{
  "thumb": {
    "use": ":original",
    "robot": "/image/resize",
    "width": 75,
    "height": 75,
    "resize_strategy": "fit"
