Creating a pdf document with jpg images for uploading to the visa website using google docs.
This is how I get my bank statements or passport in to a single pdf file to upload as one document. (for free)
I would discourage anyone from using the 'free online' pdf tools to do this.
Google is bad enough with your private data but at least it's a known website.
Would you honestly trust your bank or passport details to a completely random website?
Top tip, delete the document from google once you have downloaded it.
