First time trying this app/website. So far it has worked perfectly for what I needed it to do. So only time will tell in order for me to find out if it'll work good for any other different edits I may need in the future. Only downside so far is when I first used it I just used it on their website and after I finished my first edit I went and searched pdffiller in the app store and I downloaded the app and I started my second edit thru the app. I noticed that when editing in/thru the app I didn't have at least 1 of the features that I had/used when I was doing my first edit so I ended up closing the app and finishing my second edit thru their website bcos the main reason I needed an edit document app was so that I could delete the pages from a few documents that werent needed to shorten the document itself and in the app it wouldn't let me delete any of the pages. The only option the app would give me that had to do with the pages was if I wanted to change the order the pages were originally in then I could choose what order I wanted the pages in but there wasn't any delete pages option but other then that I love pdffiller so far! Although I really wish/think the account subscription price in order to actually use the app should be cheaper. Which for the cheapest/bare minimum options they give you is $8 monthly which I think is expensive considering. I personally think it should be at the most $4 monthly. Or have an option where it's $2 monthly and then depending on how often you use it and what you have to use it for, then there should be a small $.75¢ - $2.00 charge/fee depending on what you'll be editing and how many tools you'll be using and then that should be how the company decides how much to charge per edit and then the customer can decide what exactly they want to do for edits and what they don't etc. I don't know I just think $8 monthly is really high especially for someone like me that will likely only use it a couple times a year and I'd be more likely to keep the subscription and not just do the free trial if it was lower then $4 a month otherwise it's not worth it for me to keep the subscription after the 30 day free trial but that's just me personally

It's the best experience on pdf editors, the only thing is that i passed 10 minutes just to find how to change the color of the text, i suggest to modify the icon of the text color for better user experience and as a back-end developer I thank you for the work you are doing, work for your project, believe on it and you will have more success. I hope you share my comment with all your team, this will motivate them to do more effort for pdfFiller. have a nice day, stay positive and good luck.

Only allows PDFs. What problems are you solving with the product? What benefits have you realized? It is not possible or difficult to e-sign your documents by using other websites or applications. Best website for e-sign.
