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 2024, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.
Automatically process multiple file types
Our Robots only start their work when their input file has a file type that they can handle. This allows you to do several different things with the same Assembly Instructions. For more advanced workflows you can resort to 🤖/file/filter, but for simple use cases this may not be needed.
In the demo below, notice how the Steps image_thumbed
,
video_thumbed
and ipad_encoded
all have a value of
:original
for their use
parameter. Each Robot only processes
the files it can handle, which means that
🤖/image/resize for example gracefully ignores any
videos that your user may upload.
Step 1: Handle uploads
We can handle uploads of your users directly. Learn more ›
22s · 1280 × 720
Step 2: Resize images to 320×240
We can resize, crop, and (auto-)rotate images, or apply watermarks and other effects, and much more. Learn more ›
Step 3: Extract thumbnails from 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 ›
Step 4: Transcode videos to iPad (high quality) (H.264)
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 ›

Step 5: Export files to Amazon S3
We export to the storage platform of your choice. Learn more ›

So many ways to integrate
-
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
-
Pingbacks
Configure anotify_url
to let your server receive transcoding results JSON in thetransloadit
POST field.
