lookscanned.io VS scanyourpdf

This being said, assuming you don't need a searchable text layer on the special slide in question added as image/pdf, you may alter the appearance as if it were about an old, used paper by additional noise, blur, random rotation, gray scale replacing colors, etc. Implementations already in the field include lookscanned.io (with a repository on GitHub), scanyourpdf (their source code), or closed source supertool).

The GitHub link is prominent on their main page but what wasn't obvious was an example PDF

There is a version - it's been posted on HN before: https://github.com/baicunko/scanyourpdf

But yeah, the security implications of uploading a PDF with your SSN and signature to a random website is, um, not good.

It's open source, so anybody can look through what the code does on the GitHub page. I'm not sure how to verify that the code on the GH page is the same as the code running on the website, but I'm asking the author and I'll get back to you.
