I never got the code in my email to complete the emailing of the document to the tenant. Other than that I love the ease of using it. I hope to get help with emailed code soon.

I was looking for an app that will convert a sensitive file that has security feature that only the user or the owner of the file will only see it after it was being edited.

Time saving converter. Has made the job ahead a lot easier. Cost will probably stop me from going much beyond the trial as I have not been finding a need on a frequent basis. I will tell others about it's benefits.

What do you like best?
I like how easy it is to take a PDF and be able to type what I need to, change colors and fonts
What do you dislike?
I wish that the erase tool would be able to go in different directions, not just left and right but to be able to use it more freely to erase easier.
What problems are you solving with the product? What benefits have you realized?
benefit in using this for my business is keeping documents clean and not having to print them out hand write on them scan them back in and email it, I can do it all in PDFfiller and keeps my documents clean, and is a lot easier.

Functionality Functionality. But some links could be more clearer. For example, how to delete an entire line from a pdf? I figured it out but took some trial and error.

Experienced user back for more I've used pdfFiller in the past and it has always fulfilled the needs I've had of allowing me to fill in documents just as if I had been sitting at a typewriter (I know I'm dating myself by saying that). The ability to do so and add signatures, save documents to a cloud folder, print the documents when needed, or even have the documents notarized or submitted to the IRS is a major time-saver! I trust that the team behind this product will continue to find ways to save people like me time without costing great sums of money. Do that and I may be able to continue to find room in my tight budget for you!

What do you like best? It's ability to upload pretty much any type of document What do you dislike? I cannot really say anything I dislike about the product What problems are you solving with the product? What benefits have you realized? The biggest problem we have is that we receive uneditable documents that we are able to edit easily with PDFFiller. It's super beneficial because it saves us so much time.
