It calls itself a "PDF Editor" but its more of a PDF manipulator and PDF creator.
You would expect an editor to be able to manipulate graphics and text, and with the text to be able to; edit, add, delete, insert, format, etc.
What it calls editing is changing some tags, merging PDFs, deleting pages, etc.
The Portable Document Format (PDF) is a published format. That is once you create a PDF it is in its final stage. You can't really "edit" a PDF like you can "edit" a MS Word document. At best you can manipulate the PDF. If you create a PDF from MS Word and you want to make a change, for all intents and purposes you'd have to load the original MS Word document, edit it, and export to PDF again.
I tried PDF24 and I thought it was crap. It is based upon the public GhostScript and isn't very good.
I could do
a whole lot more in LibreOffice v3.5.2 using a PDF Import extension to manipulate a given PDF than what PDF24 could do with the same PDF.
You want to create PDF files, use
PDFCreator it has an Adobe Distiller-like capability and now includes PDFArchitect.
You want greater PDF flexibility then choose
LibreOffice with the
PDF Import extension.
** I can say PDF24 is crap because I have been working with PDFs for almost 20 years. One of my favourite things is turn a JPEG or ordinary document into a fillable PDF form where you can save data with the form.
