New to this site...just begun 30 trial. So far so good. Getting used to it but already I like much better than Adobe.

Prompt and Efficient Response
They responded to my request for chat support quickly. When on line they worked to get me what I needed. My need was fulfilled satisfactorily, even though it took quite some time. My lack of knowledge may have contributed to the length of time for the matter to be resolved. All agents were prompt.

It has a lot to offer and I love the app I just want to familiarize myself a bit more so that I can utilize all it has to offer. This app really looks as though it has everything covered. I REALLY like that!!

Easy to import edit
Easy to import edit- wished I had this a long time ago! I was desperately trying to find a way to send my Doctor forms. Scanner/Printer was knocked out from the storm.

It took a like while for me to figure out how to do what I wanted to do. But once I did, I was able to create the doc I needed. The part I liked best was the guidelines to put the fillable boxes in line with the other boxes in the document.

Why is my PDF poor quality?
If you start with a low-resolution image or other file, the resulting PDF may look blurry or pixelated, especially if printed out. PDF converters can't make your finished document look any clearer than the original. Use files with resolutions of at least 72 dots per inch for Web display and 200 to 300 dpi for printing.
How do I refine a PDF file?
To refine a PDF, click the corresponding icon on the toolbar to highlight, redact or erase any content or image. To refine your PDF further, click the 'ADD WATERMARK' and the 'VERSIONS' tabs on the right or the 'PAGES' tab on the left. When you're done revising, click 'DONE' and email, share, print or save your form.
