Hard to find the erase button. But after I asked, I found it buried in the "tools" --seems like it should be more visible. Love the tool's simplicity otherwise.

Great. But may steps to create a PDF. Also deleting pages is not included as standard. But there are easy workarounds to this restriction. So why have this restriction?

It's been very good working with PDF Filler. Makes saving forms so much easier. I only have one complaint. When it comes to dates, I usually need to write it as year-month-day; but PDF Filler is already programmed as day-month-year so I have to keep on erasing dates and fill it out by hand, which is annoying.

What do you like best?
As a beginner, I was surprised not only with the fact that PDFfiller was so much easier to learn and use than the Adobe Suite but also at the range of capabilities on offer! From my first use of this online program I found new pleasure in dealing with .pdf files. I now use the program Every Single Day to create, manipulate or convert files that used to sit waiting, sometimes for days at a time, to be done by the one or two people with access to more expensive and less user friendly programs. Now I have a new "can-do" attitude to the workings of .pdf files. I can't recommend this online tool enough and it's so affordable, you can buy a license to use at home. Great product, lots of advantages. You will not look back, you will not regret this purchase.
What do you dislike?
The user Interface could do with being a little less busy. A streamlined interface and a compact "how to..." would take a 9/10 to a 10. It just needs some tweaking and it's perfect!
Recommendations to others considering the product:
In my opinion it is definitely worth spending the small amount to upgrade to the paid version!
What problems are you solving with the product? What benefits have you realized?
Administration issues generally...adding text, file conversion and commenting on documents...are all problems that I had to either pay to have done elsewhere or ask for an expensive subscription that was never in my budget and wouldn't be approved if I had asked.

What do you like best?
The hosted forms and e-signatures are an awesome add-on
What do you dislike?
Not a big deal if you're not a developer, but the price of using their API is kind of ridiculous! $149 a month, seriously? Why don't don't you offer a reasonable smaller plan developers trying to accomplish minor things.
Recommendations to others considering the product:
Make it possible in Zapier to send contracts for signing to Send Now, looks more legitimate to clients in my opinion for signing.
What problems are you solving with the product? What benefits have you realized?
Helps me get contracts signed much quicker

Good experience but unfortunately, I don't need this product at the moment so I will not be renewing my subscription. If I decide to work on taxes in the coming year, I will subscribe.

Good for someone who isn't tech savy While I'd like to think I am pretty good with a computer -- I am by no means the level of a graphic designer or anything like that. But I do a lot of work with pdfs that need to be tweaked a bit and this is easy to use! The initial use can be a little daunting to someone who is new. But it's easy to figure out once you get a hang of it.

PDFfiller is just great tool to use to… PDFfiller is just great tool to use to find just about any documents and the ability to create fillable PDF files are great.
