I've only used it twice, but it is very easy to navigate. I am using it to send preliminary notices for out plumbing contractors business. It works great.

Overall a good experience. Sometimes the lack of features like aligning fields (i.e. Publisher) is frustrating: the ability to copy details from one field to another (drop downs and field attributes) making some forms with several fields that are the same. But I'm an old software designer so I'll take those frustrations and cherish all the good points of the software. I think its a good solution for my needs in the insurance industry.

What do you like best?
I like the idea that I can edit a PDF document that is not machine fillable. I have been using this program for several years now in personal and not for profit business.
What do you dislike?
This is not the most user friendly program to use. It lacks a search field or help section to answer questions as how to do something I do not know how to do. It would be nice to be able to save a document as you are finishing instead of having to go back and rename a document. This is the case when I am using a master form that gets updated each month. I work on my laptop and the print screen has the print button to low. I see a sliver of the print button, that if I mess around with it for a while, I can eventually click on it. I can't be the only person with this problem. It would be helpful if the print screen could open a little higher on the screen, reduce some of the preface before the print button or have the print button on the top of the form. I also get frustrated with getting an actual signature in the system. There are no clear instructions on how to do that. It took me hours and hours to get my signature as part of the program. It would be nice to be able to scan a signature into the program. I have used Adobe DC with work in the past and I find it is a superior product, but not worth the cost with the volume of paperwork I need to do. Also a typical example of issues I have with PDFiller is the instruction to take a screen shot of my log in page. I have no idea of how to do that so I attached a PDF master document I use pdfiller to complete each month.
Recommendations to others considering the product:
Don't expect to see the most beautiful documents as far as how things line up, but it is certainly a way to complete PDF forms typed instead of hand written,
What problems are you solving with the product? What benefits have you realized?
As I stated above I use PDF filler with forms that are not fillable. I have used them to complete tax returns when a fillable form is not available. I have used them to sign a document instead of having to print, sign and rescan the document before sending it back to the originator. I have not used it to obtain other peoples signature

Hassle Free PDF Editor All the hassle has been removed, I can enjoy my remaining time with my family. I can easily teach my student using PDF, and can easily send my signatures in every document to my boss. Everything is so convenient. Its really hassle to sign contracts specially in Online, what I do before is I will print it and scan it again, before I'll send to my boss, or even some papers that needed to be signed. Using pdfFiller makes my life less hassle, I can easily put my signature in different papers as fast it can be, and immediately send via email to my boss. Since I have students, I need something that are very convenient and all topics in different PDF, I'll make it in one PDF so that my students will understand better and not using too many tabs, they can focus on one PDF only and make the student more convenient in studying. I can edit also anything I want in my PDF, I can easily put pictures, highlight the important words and removing text and pictures. It cost an amount of price it would be better if it is for free so that many people can access and make their work also convenient.

Solid, provides the service you need Easy to use. Mostly used for inserting signatures. Sometimes the signature block format gets distorted (inserts as a code).

Fairly easy to navigate Fairly easy to navigate. Text does not always line up exactly right, but close enough to make the document readable. Overall, very pleased with the service.

What do you like best? Ease of use, flexibility of tools and automatic saving. Full encompassing product, re-write, over test, add images, move fields, add e-signatures, and complete forms. All gets saved in a highly professional manner, and saved automatically to my own personal files. What do you dislike? Having to re-verify login each time I visit the site often with delay whilst an email arrives, sometimes have to click through multiple screens. Recommendations to others considering the product: Try it, you'll be immediately hooked. On first use, give yourself 10mins to familiarise yourself with the product it is incredibly intuitive, easy to teach onesful. What problems are you solving with the product? What benefits have you realized? No Problems, benefits are to adjust and edit pdf documents with ease, adjust previously written words, add to them, over right, add images.

If you really want to make your lettering pop like whoa, then you just need to add highlights! Add a shadow in your favorite style. Then, using a white gel pen, add small lines on the opposite side of the shadows. Put your highlights near the edge of the letters, but not right against the outside.
The basic rule: The shadows should appear on the opposite side of the light source. If your light source is on the left side, the shadows should appear on the right of the letters. If your light source is on the right side, the shadows should appear on the left of the letters.
Select the text that you want to highlight. On the Home tab, select the arrow next to Text Highlight Color. Choose a color. The text you selected will be highlighted in the color you chose.
