What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
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!

I LOVE THIS SERVICE SO FAR. IT HAS ALLOWED ME TO CREATE THE DEMOGRAPHICS FORM FOR TAX PAYERS IN THE LAY OUT THAT I ALWAYS DESIRED. THE BONUS TO THE LAYOUT IS THE PDF FILL IN THAT ALLOWS YOU TO INSTRUCT THE CLIENT RIGHT WITHIN THE CELL. THE SEND TO SIGN FEATURE IS AMAZING IT ALLOWS ME TO OFFER A FASTER SERVICE WITH OUT HAVING TO HAVE A PERSONAL INTERVIEW.

Best Friendly user software It was great, very useful when it came to modify and add wordings to documents or even signatures. I like the availability to modify and edit your documents, it's very easy to use and it has so many features to get your documents corrected, sent, faxed, emailed and more. I didn't like when adding texts to your documents, sometimes it will freeze and close the program. Then again it was the free trial.

I somehow allowed my subscription to renew, when I actually do not need this service. A quick contact with customer service handled the problem for me and I got a full refund. I was aided by a representative named ***. No hassle!
