I like it but felt that my "free trial" was a bit of a scam. I spent hours on a document, learning your program but was unable to print it. I don't like being "forced" into purchasing a product.

Amazing product! I was able to fill a tax form very easily and sign it. Better than all others I've tried! There are two comments for the development team and marketing team: 1/I expected a free trial, and 2/There are so many options that it can be confusing when you are just starting. I would have appreciated less options up front and some video tutorials to introduce me to advanced features.

It's not as intuitive as I hoped to use the mobile apps, and it seems there are many steps to doing the main process which led me to purchase PSF filler--uploading and emailing HIPAA related documents that I've photographed. I'm sure there'll be a learning curve, however, so I am still hopeful. With two helpful and timely chat guidance, I was able to resolve my problems with scanning and uploading photographed documents quickly. I still wish the mobile app allowed me to rename the document so that I wouldn't have to fiddle with it later in the browser app, but am happy with many other features at this point.

What do you like best?
Program is very intuitive and easy to use. I spend less than 10 mins to recreate a document for Customers and it makes a world of difference.
What do you dislike?
I don't think I have any dislike...or at least none that I've come across too.
Recommendations to others considering the product:
It's a must have program...so easy to use and it does it all. Plus an extra bonus is that it's less in cost then the highest competitor. WIN, WIN!
What problems are you solving with the product? What benefits have you realized?
I edit our invoices & receipts. I'm able to provide progress invoices that our system doesn't do. This helps our Customers tremendously to understand paperwork.

Easy to use! I found the system very easy to use and have only scratched the surface. Converting documents to an editable form was easy to do and the system made it easy to find available PDF or other formatted versions online. Saving different versions or templates was a bit of a challenge but that was easily remedied.

What do you like best? The site is very easy to use. The layout and design make it very simple to choose the best option for formatting documents. Choices for template or regular document helps to organize which docs you need to reuse. Even if you are not experienced, the options to choose from are so clear, you cannot make a mistake....and if you do, you can fix it very simply. What do you dislike? For me and my business purposes there is nothing wrong with this site. It is perfect and has made my business practice so much easier. Recommendations to others considering the product: Best program for editing documents, reduces additional work time creating new doc, great advantage with template option. If you are considering a program that will effectively improve your ability to create, organize, and edit important documents pdFiller is the best choice! What problems are you solving with the product? What benefits have you realized? I am in the field of Special Education as an administrator. This year with COVID-19, the difficulty of having documents signed, changing information and moving paperwork quickly has been a real challenge. With pdFiller, I have been able to address any paperwork issue that arises in an instant and then get documents back out for a new signature, or an update of information. This has saved me this year and helped me to meet all major and important timelines.

The PDF filler is amazing The PDF filler is amazing. It has solved me in so many situations since being in isolation due to the fact that I do not have a printer. So easy to use. The only feedback is the date component is fiddly and doesn't always work but other than that - perfect.
