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.
Filter out files that are smaller than 1KB
🤖/file/filter allows you to decline files that are smaller than a certain size.
⚠️ 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 allowlist of blockers usually helps.
Step 1:
Handle uploads
We can handle uploads of your users directly. Learn more ›
⚠️ It seems your browser does not support the codec used in this video of the
page.
For demo simplicity we'll link you to the original file, but you may also want to
learn how to make videos compatible for all browsers.
Step 2:
Pick files with a filesize of 1 KB or higher
We let you reject, or direct files against different encoding Steps. Learn more ›
⚠️ It seems your browser does not support the codec used in this video of the
page.
For demo simplicity we'll link you to the original file, but you may also want to
learn how to make videos compatible for all browsers.
Step 3:
Export files to Amazon S3
We export to the storage platform of your choice. Learn more ›
Once all files have been exported, we can ping a URL of your choice with the Assembly status JSON.

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
-
Pingbacks
Configure anotify_urlto let your server receive transcoding results JSON in thetransloaditPOST field.
