What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
The forms are good but they would be much better if the user could "snap to" the proper location when typing into a box. Without a "snap to" type guide it is difficult to place the cursor in the correct location within a box and especially difficult to get columns to line up.

I am happy with PDFfiller for the most part. It is a very good editor that makes a normal document look sophisticated. My only complaint is the price. 15$ a month for this? I mean it is a good editor, but 175$ a year is to much for me. Overall, it is a great app for editing with a great package of fun.

The form was fairly easy to alter and… The form was fairly easy to alter and print. However, I did have a lot of difficulty inserting text into the box below the name of my company. I was not able to make the font different sizes for highlighted text which was even on different lines. I did not make the form the way I would have preferred but I am overall satisfied.

Working Experience With PdfFiller i am using this software for about 8 to 9 months. the best thing i found in this software was its feature to send the file online without makuing sure to save first and then send. other feature i liked the most is that i can easily edit the pdf format by using this software. it is really very favorable feature to avoid the conversing to word file for editing. in my opinion, there must be improvement with the font size of editing text to make it more compatible with text. i face a problem to make the ediding in the same font size . Althorugh, it is same as that of text but it seams different. it makes the file less professional.
