Thank you for providing a quick easy and accessible way of editing pdf files that have permissions blocking from editing the file itself
Very helpful for merging and deleting un needed pages in documents! Only issue is loosing the ability for the fillable spaces I created when I upload.
I had a billing issue and customer…
I had a billing issue and customer support identified my problem and solved it with ease, no hassle, and immediately. Just good customer support. That makes the entire experience worth it, and the product worth paying for in my opinion.
All trials have been very satisfactory. It has been easy to learn the use of the various features. Especially the relatively small size of the ready documents is appreciated.
Even Adobe editor couldn't help
I needed to change one document and even adobe software couldn't help. The only possible way was to sign up for a free trial. I forgot to end the trial and when I was charged, I contacted the support centre and they return me my money straight away. Very happy with the product and their support service. Would be happy for an option to pay for a single-use, as I'm editing pdf files only a few times per year.
