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.

After a slow start and feeling misled by the "fill in your form for free" and then having to pay, I did get a full refund. The tech support was excellent - they were the only ones, that I could find, that could get me the rather complex fill in form from NY State Tax authorities (RP-5217). I still feel I should not have to pay a third party to file a required tax form - but that is an issue I'll have to take up with NYS, wish me good luck with that one.

I have been having trouble finding forms, and then getting the fill-in fields to work. While I like the end product I'm frustrated that it is not more user friendly.

Great service! Could use some updates though. The site is rather slow at times, and when changes text size there seems to be a bug where the page needs to refresh or reload. Also, general improvements on loading time would be nice. Also, please make the process of saving to PDF less steps and less clunky. I don't need to be shown where the pdf will be once downloaded.

Easy to use online PDF editor This is an easy to use app, which allows the editing of PDF files from any source with multiple tools to work on any pdf document of the company, it is a solution for filling out forms, it allows inserting comment or image. I can also combine, divide and reorder, cut, place header and footer, watermark text or image in my documents and has a preview panel. As it is an online editor it does not consume resources on my pc and it is compatible with all browsers You can edit documents from any device but it is mandatory to have an internet connection to use it, so you can not have it as the only editing tool.

PDFFiller I liked being able to create customizable fillable forms for our company. Overall, it is easy to use and responsive. PDF filler is great for a digital signature and saves your previous signature for efficiency. the customizable form feature sometimes lagged and caused minor issues.

Great service. I thought my subscription had expired but the tech support hooked me back up in a jiffy! I prefer to use PDFfiller program rather than the Acrobat Reader DC program. I will always renew my subscription in the future.
