Loving the tool. It would be great if you could add an eye dropper feature so that if I alter text or numbers that are over a color background I can erase the copy fill in the area with the original background color and then revise the copy over the background fill

I would give it a 5 except that when I go to edit a template, it shows up with over 1/2 or 3/4's of the page covered up! I have to keep closing it & reopening it to maybe finally work! Very frustrating.

I wish I could change the location of saved files. Everything saves to downloads even when I choose desktop.
What problems are you solving with the product? What benefits have you realized?

est money spent Filling out forms on the daily used to be such a pain. Now it is easy! so much better than printing a page, filling it out, getting my boss to sign it, scanning it, and emailing. upload a signature, fill it out, email or save to computer. easy peasy Honestly nothing. If I HAD to complain, scrolling from page to page on a multi-page document isn't always smooth scrolling.

A very useful tool for paperless office work. It helps me to save paper and electricity by not using physical papers for my office documents. I do most of my office work online only with the help of this software. It allows me to get e-signatures on my office documents. Being a cloud based program it allows me do all my pdf related work online only. I don't find auto save feature in this application. I had to lose my unsaved work many time when I closed my system accidentally.

I am having some difficulties with the…formatting and printing I am having some difficulties with the form printing properly. The formatting does not transfer for printing to landscape and thus loses portions of text contained within the form.

I've been using PDFfiller regularly for over 2 years now, and it works wonderfully. I'm able to upload documents, add fillable lines, and get electronic signatures seamlessly. Customer service is also great - prompt and friendly in attending to any questions or issues. Makes running my business that much easier.
