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 2026, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.
Encode video for browsers in 720p
There are different browsers from different vendors that try to push different video codecs. In this demo we generate a few different videos to ensure maximum compatibility with all browsers. We also generate a thumbnail that you can use as a poster
We can use WebM's VP9 codec for modern browsers and fall back to MP4s for the rest like so:
<video controls playsinline poster="thumbed.jpg">
<source src="browser720_webm_encoded.webm" type="video/webm; codecs=vp9,vorbis" />
<source src="browser720_h264_encoded.mp4" type="video/mp4" />
</video>
Step 1:
Handle uploads
We can handle uploads of your users directly.Learn more
":original": {
"robot": "/upload/handle"
}Step 2:
Transcode, resize, or watermark videos
We offer a variety of video encoding features like optimizing for different devices, merging, injecting ads, changing audio tracks, or adding company logos.Learn more

Loading Uppy demo…
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.
Build this in your own language
<!-- This pulls Uppy from our CDN -->
<!-- For smaller self-hosted bundles, install Uppy and plugins manually: -->
<!-- npm i --save @uppy/core @uppy/dashboard @uppy/remote-sources @uppy/transloadit ... -->

So many ways to integrate
Transloadit is a service for companies with developers. And there are many ways developers can put Transloadit to good use inside your company to automate media processing.
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.
On-demand
Use our Smart CDN to adapt files on-demand and stream them directly to your users.
Video encoding
Document processing
