We are a Swiss Army knife for your files

Transloadit is a service for companies with developers. We handle their file uploads and media processing. This means that they can save on development time and the heavy machinery that is required to handle big volumes in an automated way.

We pioneered with this concept in 2009 and have made our customers happy ever since. We are still actively improving our service in 2018, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.

Convert all pages of a document into separate images

Our /document/thumbs Robot allows you to convert uploaded documents into separate images. It supports extracting a specific page (with the page parameter), but also converting all pages (if you leave the page parameter out).

Warning It seems your browser does not send the referer, which we need to stop people from (ab)using our demos in other websites. If you want to use the demos, please allow your browser to send its referer to us. Adding us to the whitelist of blockers usually helps.

1. Handle uploads

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

/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. Extract thumbnail images from documents

We can process your documents in an automated way, saving you costly resources. Learn more ›

  use: [':original'],
  robot: '/document/thumbs',

/document/thumbs Robot
This bot generates an image for each page in a PDF file or an animated gif file that loops through all pages

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.

Try it in your account

Copy these instructions to a Template of your own
(you'll be able to make changes before actually saving)
