very intuituve. quick and easy to learn. i operate mobily so i like the fact that i can use it on any of my 4 computers any where in the world. Very easy to drop text in. I like the erase and highlight feature. I tried at least 6 other platfroms and they were too dificult to use.

Definitely works. Not sure if there is a way to make figures line up just a little better or have calculated fields, but definitely better than just using adobe acrobat

PDFfiller Overall, this product is good and I would recommend it to a friend. Like it over Adobe. When I played around with the trial, I liked how you had many options and the program layout was nice. Love the ease of use when trying to alter a pdf. I wish I had a longer trial period and sometimes I could not save a file causing me to save over the original file.

It is easy, so relax and just do what you need to do. I am so very, very pleased with how easy the program is to use. I tried others for this emergency situation and was frustrated out of my mind with the complicated programs. This one is easy, easy and very effective.

THIS THING IS A DREAM (although I did have some kind of issue opening up a file.) I used the MERGE function and it merged some files I didn't need. That was weird. So I'm editing one page at a time instead. That seems to be working.

it's good, needs to be smoother and faster response time. need find and replace function. and when something is replaced the original value should disappear.

I really like the capability of downloading forms, completing them and signing to send off. I wish I did not have to log in each time. That would be a great plus as I work for several clients and need the quick ability to do a form and send to them. Thank you Alice

It will resample and compresses images and subset-embeds fonts that were left embedded. It also compresses document structure and cleans up elements such as invalid bookmarks. If your file size is already as small as possible, the Reduced File Size command will have no effect on the size of your document.
While Preview can reduce your PDF, it isn't able to preserve image quality. The problem with Preview's built-in file compression is how image quality drops drastically afterwards, causing any image or graphic in your PDF to look blurry and at times incomprehensible.
