Frequently asked questions

How does it work?
We use WebAssembly to execute more complex logic, that is needed for the PDF modifications, inside of your browser. This way we are able to offer you functionality that runs directly on your device and keep your data private.
Do you make any money out of this site?
We try to make up some of the cost that we pay for hosting this service by employing a small amount of ads on our website. Please disable AdBlockers and other scripts on this site completely.
Why did you create this website?
Just like you we need to edit PDFs. We did not want to spend a fortune for a program so we searched the web and found a lot of websites that enable you to modify PDFs. However, one always needs to upload the documents to their server and we found that a bit dubious, as you do not know what happens in the background with the data.
