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.

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. Import files from webservers

We are happy to import from whatever storage solution suits you best. Learn more ›

"imported": {
  "robot": "/http/import",
  "url": "https://demos.transloadit.com/inputs/chameleon.jpg"
},

/http/import Robot

This bot imports any file that is publicly available via a web URL into Transloadit

2. Resize images to 130×130

We can resize, crop, and (auto-)rotate images, as well as watermark them. Learn more ›

/image/resize Robot

This bot resizes, crops, changes colorization, rotation, and applies text and watermarks to images

3. Export files to Amazon S3

We export to the storage platform of your choice. Learn more ›

Once files are exported, we ping you back with the Assembly status JSON.

/s3/store Robot

This bot exports encoding results to Amazon S3

Since this is a store robot, be sure to use Template Credentials so that any sensitive data is encrypted and stored in our database, making sure that they’re never exposed to any end-user.

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.
