Zilla PDF Editor 4+

Edit PDF files and delete PDF text easily.

Zilla PDF Editor is a software application on Mac OS X that allows users to add text, insert images, put watermarks to label their copyright, changing font size and color, and perform other changes of a PDF document.

After adding text and images, you can change the text font and color, resize the image height and width or move them as well. If you need to delete some words or text from the PDF, simply click on the eraser tool then erase. Rotating certain pages and modifying document layout is also important so as multiple drawing tools like lines, brushes, horizontal lines or vertical lines. Better than normal PDF Readers and Annotators, Zilla PDF Editor can permanently save the modified PDF content changes.
