For several years I used this service as I ran an on-line business and felt that the ability to create pdf files, for ordering processes would be of a significant help. I am now retired, but like the ability to modify medical health forms rather than filling them out by hand repeatedly.

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.

Excellent, efficient, immediate, professional service by *********. Very impressed with th level and quality of handling my request for refund as I only had to use the service one time, but let the "Free Trial" time frame lapse. The subscription charge was immediately refunded on the day it was debited for a one year subscription.

Impressive customer service (LIVE support) I did not realise that my free trial expired until I got a charge for the month of December. I contacted 'live support' (which popped in in 20 sec) and Thomas was the most helpful I've ever experienced in customer service. He found out I had 2 accounts and when I explained to him that I actually only used the service once, he promptly offered me refund. I did not even expect one because I honestly thought this is another website that makes money by offering a trial and then charge you once trial is finished (which many of us would forget and only cancel when it is too late). But no, refund is already action, and he also cancelled my account as per my request with no fuss! Thomas, thanks for being extremely prompt and helpful! I will surely use this service next time. Thank you!

Great software Loved the ease of this software - it saves lots of time. This software is so so easy to use and makes filling out forms then saving those forms so much easier. I found no cons with the use of this software. It was so easy to use and eliminated filling out by hand.

You can increase the resolution of images to ensure that a photo you want to use can be adapted to your project. Resizing a low-resolution image doesn't add the additional detail that would be apparent in a high-resolution original photo, but it increases the usefulness of many images.
