What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
On first blush,this is a fine tool. I have a limited number of documents. So this works great. Simple. Easy to follow. Support answered some not so obvious questions quickly and easily. Well done. I have one question or suggestion..I would like to merge a couple of my documents...but don't want to pay for a full upgrade for just two or three uses. Can you offer a "yeah we'll let you do this" one off pricing for someone like me? Would be very helpful. (I will also say I tried several of the competing products...and this was far easier to use)

Better and more powerful document management and editing on the web Editing my PDFs without difficulty This PDFfiller tool for online use is very useful since most PDF editors are paid and not all people can pay for such software. It also allows you to upload the documents you have in your Google Drive account, Dropbox and other tools I do not find you disadvantaged, because you are covering the need of users who can not afford desktop software, to edit a PDF document

I am using it time to time for to fill the pdf. I got this because IRS fillable from will not let me I have used IRS form like 1099 and 1096 and other forms. Easy to move PDF and update. Also I can save filled PDF to my folder. I really like the filled and sign.

I was a bit unsure about whether non alphabet/numbers should be added. I was also unable to add my initial after my surname (just typing it) as the filler kept on opening the initial (as in signature) block.

Tons of functionality for a great price. Excellent customer response time. Feedback: when using the "home"/"end" keyboard buttons, it immediately takes you to the top/bottom of the form instead of beginning/end of the text box you are editing. Just an unintuitive and weird feature. Also, it would be great if there was a way to save LinkToFill settings so that they can be applied across other documents. Overall really happy with this product!
