Top Four Frequently Asked Questions

What about security (and also testing on localhost) - do I have to make my webpage publically available?

No - you can send the html (instead of a url) - there is no need to put the page you want to convert publically on the web. This is also slighly faster as we don't have to download the webpage from the internet.

If I do use the URL option, what security options like SSL are there?

You can use basic authentication and pass in a username and password. Our API supports SSL and also reading from https pages. Alternatively some customers use a simple token system, e.g. by passing a secret parameter on the url that noone else will know, e.g. The token could be simple - the same each time, or it could be time based and expire after a minute or so.

What about data privacy?

We take privacy very seriously and we do not store either the webpage content you sent to us or outputted PDF. Not even in audit trails or exception logs. HTML is processed and sent back to you, and to be perfectly honest, storing all that html, css, images etc or worse, the resulting PDFs would quickly result in terrabytes of useless data that would cost us a lot of money so doesn't make any sense - we also do not have time to sift though tens of thousands of PDF's to find one with something interesting.. Please see our privacy policy for more details

Can I run this on my own private server or cluster?

Yes - we have sent the API source code to several companies, and we can also spin up a dedicated server, or server cluster just for you drop us a line.
