I was very upset that I wasn't told I'd have to pay until after I'd edited a very long file, but customer service gave me 30 days free when I brought this to their attention.

I'm impressed with PDFfiller but I think there could be more options of background colours of the textbox, including different shades within each color.

PDF Filler For me Im tech savvy, so I can quickly find my way around for the features that I need myself, however for others they may find it tedious to find the feature, maybe I feel that way because I went through google suites, I was also disappointed at the extremely low rating, however most people must complained that it was not free, which is not really a big issue, no software is totally free, they need to make money, so they will surely make some features available as trail, if you need more stuff then pay, 100%, I don't agree with the negative reviews., that's why I stuck around for the software. I love this software, actually it is one particular feature that is EXTREMELY attractive for me, which is the ability to make a form that is 1) fillable, 2) electronically signable, 3) that can be available via a link, 4) that can be placed on a website, 5) and best of all accessible only by secure login. All these features are amazing. Not so clear features however I'm tech savvy so I had no problem, others they may find it tedious to find needed features. I was also disappointed at the extremely low rating.

Great Program to help buyer's get their electronically signed documents It makes it much easier for the buyer to get documents that can be electronically signed. Quality of the documents that get sent to my buyer's is fantastic. The look of the documents are professional quality Ease of use. It is hard to remember how to set up the file to get to the buyer quickly. I always have to try it 2 different times to get it right.

What do you like best? I enjoy PDF Filler because it is not as expensive as Adobe Pro, and it allows me to quickly edit, sign, and return any PDF document I would normally need to print out, and scan back to myself. What do you dislike? One dislike I have is the fact I need to download everything. It would be really helpful if everything would be automatically saved on something like a onedrive (cloud storage), where it would be automatically saved. This way, I can have a local folder on my computer without needing to go into the webpage and click download What problems is the product solving and how is that benefiting you? I no longer need to waste paper to download a form, and fill it out. Normally I would need to do this, then scan it back to myself. now I can upload, edit, and sign the form which saves a lot of time.
