I have been a short time user. I downloaded a document; tried to then sign it, which was ok, but when I downloaded it did not pick up the entire form; all preprinted matter on the form did not download to the email I sent. Tom

The PDFfiller service was very comprehensive and easy to use. I really appreciate the options for document delivery and would recommend this service to colleagues who could benefit from this service.

For the most part, it is a helpful tool. However, I will need to cancel my initial free subscription because one of the documents I would be using on a bi-weekly basis would be for payroll purposes. Unfortunately, when I scanned the document, I was not able to enter numbers in the fields. After several attempts, I checked the hardcopy document and it has a feature, which requires an applicant to fill in the document with a blue pen, something I was not aware of ahead of time. Evidently, the company had the documented protected to only read "handwritten", blue pen entries. I would be using the document as mentioned above for other candidates on a weekly basis and since this product, through no fault of its own, won't allow me to do that, it doesn't serve my business purposes.

I cannot believe how wonderful this website is!! I can edit any PDF, fill out forms, send from the website and they even have an option to mail it for me! Definitely exceeded my expectations and I've never seen any other website or app like this. I KNOW I will be renewing this every year, especially how affordable it is!

Positive review It is so much easier to get my scholarships done. I hate writing on my scholarships, so I was having to completely retype the application which was taking time from me filling them out.One suggestion would be to do a student discount, like in my case using it for scholarships. A way to do this could be they have to enter there school and get a school code from someone and then that could verify they are a student so the company is not getting taken advantage of.

The reason it is a four instead of a five... The reason it is a four instead of a five is I feel like there is a strong learning curve... at least for me. So I am still learning. Check back with me in a month and let's see if we can delete this 4 rating and move it up to a 5!!

What do you like best? The ease of use, the verification of signature and the compatibility on all types of documents What do you dislike? The cost...yearly is pricey considering there are programs that you pay more upfront but it’s a one time fee What problems are you solving with the product? What benefits have you realized? Making my documents fillable for my students while teaching remotely
