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 🤖/html/convert make a PNG screenshot from the Uppy website.

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

⚠️ 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: Take screenshots of webpages or HTML files

We can process your documents in an automated way, saving you costly resources. Learn more ›

🤖/html/convert

This bot takes screenshots of web pages or uploaded HTML pages

Step 2: Resize images to 1024×768 using the fillcrop strategy

We can resize, crop, and (auto-)rotate images, or apply watermarks and other effects, and much more. Learn more ›

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

Step 3: Export files to Amazon S3

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

resized

Once all files have been exported, we can ping a URL of your choice with the Assembly status JSON.

}

🤖/s3/store

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.

Live Demo. See for yourself

This particular demo does not rely on file uploads and is therefore typically not initiated from web browsers. However, just so you can get a feeling for our service, we’re happy to let you run this right here regardless.

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
