Take a screenshot of a website automatically (by using a URL)

Transloadit can take a screenshot of any website or HTML file. In this demo below we let the /html/convert Robot make a PNG screenshot from the Uppy website.

You could optionally use the /image/resize Robot to further resize or crop the resulting image as required.

3. Export files to Amazon S3

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

/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
