What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
It seems it is a bait and switch deal. You think you are getting a month for free but to really use the form without watermarks like SAMPLE across it, it seems you have to pay.

Some of the text sizes seemed to change when editing, and the positioning of the text didn't always seem to be consistent with existing and added text

Had an issue with billing today (a Saturday) however after emailing their customer service team I got a very quick response and kept getting help and support until the issue was resolved, on the same day. The person I was in contact with was very polite, understanding and genuinely wanted to help. The service itself is great and I would recommend it to any business that needs to edit and sign documents online .

Great support from the team, especially Kara
Over two days I talked to several agents. Kara was able, with great patience and time commitment, to solve my problem. Anything I have paid for the program and year subscription was was worth the service I got. I hope she is recognized as the best! Thanks to the program but most of all to her. Great job!

There are few issues while importing already filled up PDF files. I would recommend to import the empty form and start filling.

VERY EASY TO USE PLUS ONE SUGGESTION
VERY EASY TO USE. THE ONLY THING I THINK NEEDS TO CHANGE IS THAT WHEN I SAVE THE DOCUMENT, INSTEAD OF SAYING IRS FORM 940 (OR SOMETHING CLOSE TO THAT) I THINK THE YEAR OF THE FORM THAT WAS WORKED ON. FOR EXAMPLE: IRS FORM 940 2019
