The software is very user-friendly and FAST! I have purchased several PDF software programs through the year and many times Nuance Scansoft PDF (ver. 2, 3, 4, 5, 6, 7) and have purchased the Foxit (Phantom PDF) one. I can say that the ease, the speediness of filling out PDF forms and its online platform make PDF Filler my number ONE PDF software now. I have only one recommendation. If you could make a tryout period available for the Professional and Business versions, that would be awesome!

pdfFiller is great so far pdfFiller is great so far, but I would like a bit more comprehensive editing tools. For example better alignment options for fields, even spacing, more flexible sizing options, and maybe support for tables. Also, right-alignment of fields works on-screen, but always prints left-aligned. Other than that, the ease of use and clean interface are a pleasure to use.

This morning my subscription to PdfFiller was automatically renewed. Once I realized it, I notified the company to cancel my subscription and to provide a refund. Within a short time, I received a response confirming that the subscription was canceled and that the charge was reversed. I would definitely recommend this company and would use them again if I had a need.TL
