Say yes to PDFfiller. I was able to take a 30+ page PDF file, highlight areas of significance, add sticky notes and/or note boxes where I needed to remember a particular point in the lengthy document filled with legal jargon. Which made things SO much easier for me. Although I have listed a few things that I wish were different, overall the product is a great one. I had one difficult experience with a file, but otherwise everything has been amazing. I would absolutely recommend PDFfiller to anyone needing the tools it offers. I had never used a PDF editor before. Simply due to the fact that I had a hard time finding one that wasn't trying to charge me a bunch of money up front. PDFfiller gave me a free 30-day trial. Which is an instant gold star in my books. Aside from the willingness to let it's potential customers try the product out, the product is surprisingly easy to navigate through, and I was able to download a copy of my final product free with the trial. There are two things that I would change if I could. The first thing that I did not care for is honestly just one of those particulars that I would have like to have the option of. That being that the only highlighting option is yellow. While this is not really a big deal, it would be really nice to have the option to select different highlighting options (pink,green,orange,blue,etc.). As a college student, I handle a LOT of PDF files on a weekly basis. Anything from a single page reference list, to a PDF copy of a book that consists of hundreds of pages. For me, color coding highlighted areas makes research points easier to decipher and organize according to relevance to one another. The one thing that I noticed was a bit of a headache to deal with. I uploaded a file that needed updating. I selected a entry point that needed to be changed, and the font size automatically changed from an 8.5 to a 9. I selected the "text size down" option, and it made it a size 8. There is no option to size it back to an 8.5. This created an abnormal look to the line of text, and one or more words were different in size. I would have to go through and individually adjust everything to the same size. This may be a subtle difference in size, but as a Graduate student, these things matter in the grading process.
