Once you get used to the typing sequences - it is the bomb!!! DITTO but at first it is extremely frustrating & if do not use it on a regular basis - you always recall the truly pain in the ----- re this aspect.

It can be great, but it's a little buggy at times. The signature feature often crashes the signer's device, whether mobile or desktop, and the API integration with Zapier is very finicky as well.

I looked through all of the court libraries, many online results, etc to find what I needed to represent myself in court against my ex to defend my parenting rights, and this was the only place a found the form I needed, that was writable and downloadable. I appreciate this so much in such an already stressful situation, thank you pdfFiller.

I am very happy with the customer services of pdfFiller. I am very happy with the services of pdfFiller.com Their customer service is excellent. A payment was automatically made from my credit card. However, after talking to the customer service, I got my refund which I never thought would be possible.

Communication & follow through on point. Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and an effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed up for the 1year subscription. I contacted the help desk, and advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. Their reply communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month, refunded the difference $114 and cancelled my future subscription. I would happily use this again. Thank you very much.

Worthwhile and a pleasant suprise! Was originally looking for something to modify a PDF with but with this website, I got more than I could ask for!

I love the fact that a function stays the same until you change it, eg. a font size and format. However, I would like the option to use all the Fonts that I have installed on my own computer. When a page is duplicated, I'd love it if the 'changes' made to the original using pdfFiller, could also be duplicated rather than simply a duplication of the original document. I also can't seem to find a way to cut and paste text to apply it in a different area of the document, which means that the process of replicating a change is more time-consuming, but this could be my current unfamiliarity with the software. I was impressed that within a couple of hours of use, I was offered the option to attend a webinar to improve my understanding.
