We are a Swiss Army knife for your files
Transloadit is a service for companies with developers. We handle file uploads and media processing for them. This way they can save on development-time and heavy machinery that’s 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’re still actively improving our service in 2018, as well as our open source projects uppy.io and tus.io, that are changing how the world does file uploading.
Import files over HTTP
Sometimes the file you want to process is already available at a specific URL and you do not want to upload it again. For these cases, this robot is just what you need.
1. Import files from webservers
Transloadit is happy to import from whatever storage solution suits you best. Learn more ›

2. Resize images to 130 × 130
Transloadit can resize, crop, and (auto-)rotate images, as well as watermark them or read & write meta-data. Learn more ›

3. Export files to Amazon S3
Transloadit is happy to export to whatever storage solution suits you best. Learn more ›
Once files are exported, we ping you back with the Assembly status JSON.

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. -
Backend integration
-
Pingbacks
Configure anotify_url
to let your server receive transcoding results JSON in thetransloadit
POST field.
