JUST HOPE THE INSURANCE COMPANIES WILL ACCEPT THIS FORM AND PAY US. WISH IT HAD A CAPABILITY OF ALIGNING ALL LINE HORIZONTALLY SO IT DOESN'T LOOK SO HAPHAZARD

It was really easy to fill out the forms and print them. Normally, I wouldn't spend money for this type of service, as I can just print the PDF document from the internet. This time, however, I just didn't want to have to write all the information. Also, if I wanted to make changes, I loved that I could change any field and not have to write over it (as I would have otherwise).

The price is kind of crazy, I am a single mother of 3 and I am on a limited budget. The program itself is fantastic, but the price is hard for me to justify buying. :(

I've had a great experience using PDFfiller. Sometimes, I have single forms to complete, and I forget that I have the service. It's user-friendly. I need to make time to do a tutorial to learn more uses. Also, once I become better familiar, I'll be able to make referrals to sign-up for PDFfiller!

What do you like best?
PDFfiller actually has lots of online tools that can help with many general document editing tasks. We can convert PDF files to lot of different document formats such as DOC files, which are files I use often at work. For document signing, editing and adding fillable fields is not complicated. The toolbar has tools that are neatly laid out and easy to access. There are lots of click-and-drag features that make using PDFfiller comfortable, even with hours of editing. There are also helpful collaboration options that let internal staff communicate about document edits.
What do you dislike?
From an admin perspective, it's been a delight working with PDFfiller, but some people that receive our digital documents can sometimes have trouble accessing the files and knowing how to sign them.
Recommendations to others considering the product:
PDFfiller can be a valuable solution if you need to make lots of edits to PDF files and don't have a much experience with more advanced software like Adobe Acrobat. It seems to be designed for beginner users, but can also work for more expert document editors.
What problems are you solving with the product? What benefits have you realized?
Even though I know how to use various popular PDF and document editing software, I often turn to PDFfiller to allow for more intuitive editing features and its abilities to work with just about any PDF we load into it. It's a versatile editing solution that lets us quickly format our documents to our specifications.

I genuinely love this program I genuinely love this program. I don't have to wait for anyone else to print things for me and then get backed up on my work. I can just create what I need and send it right then. Super simple and user friendly.

PDF Filler Descriotion It has been wonderful from the online accessibility to the ease of computer use. The screen font was adjustable, so I like that it is non-discriminatory. This software is affordable, and saved me some job hunting in person. It allowed me to sign some paper stuff online. I o not like that this software left out the name of the company whose creator devoted it to. In addition, it leaves out some colors like blue and black from a police department.

Helpful for Digital Signature Overall the PDF filler is amazing and free! These days, a lot of people don't have printers and scanners. Also, a lot of us are working from home. This software makes it possible to sign documents without printing and scanning. My least favorite thing is that you have to create an account to save your document. It would be nice to not have to provide my email to save the document.

The software worked great but didn’t… The software worked great but didn’t quite fit my needs as a student who uses pdf editing 90% of the time to write with a stylus for exams. The reason I gave them 5 stars is for customer service. They were very kind and helpful when I contacted them about my account.

A certificate stores the public key component of a digital ID. For more information about digital IDs, see Digital IDs. When you secure a PDF using a certificate, you specify the recipients and define the file access level for each recipient or group.
An electronic signature, on the other hand, is merely an image of your signature overlaid on top of a PDF document. You can do it with all kinds of apps, and it's what most people will require when they send you a document to sign. Send them a PDF file with a digital signature, and they won't know what to make of it.
