Infix 7.6.9
"Infix is a revolutionary new word processor that lets you edit PDF documents. Infix is a PDF Editor that is fully functioned and easy to use. For the first time it's now possible to edit text in any PDF document using tools familiar to anyone who uses a word processor. Easily edit the text in your PDFs, reflow and justify, change fonts, colours and sizes.
The Infix PDF Editor has been created to help with the most common PDF editing tasks - rewriting text and replacing images. Say, for example, you need to update an old product's User Manual; using the Infix PDF Editor you can make seamless text edits and update old photos with new product shots. All without having to revert to the original source document - which may even have been lost or mislaid."
