What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
There's no instructions of what forms are available. I use two that I've researched and used but a listing of all forms and a more convenient method of printing would be helpful.

This program has been THEE most useful tool for me in my professional life. I am still finding useful surprises. I can't imagine what I would do without it.

What do you like best?
It offered me a complete fillable PDF forms using data from spreadsheets in a matter of minutes. It Kept all of my completed forms secure and organized in one folder and I could easily access them anytime from its desktop software or its mobile application. PDFfiller’s add-on for Google Spreadsheets spared me tons of time I would use filling out multiple forms with data from my Google Sheets by hand. PDFfiller instead allowed me to automate the entire process by quickly merging data collected from the spreadsheet’s cells with fillable fields in the forms. It also helped me to easily share completed forms with my teammates and colleagues directly from it instead of having to download and share on various platforms separately.
What do you dislike?
It's a bit slow and too many requirements to return to the dashboard to make a new order or start over. It's a little difficult to use and I didn't really find the editor interference convenient at all. Also if you're using it online you should have a medium to fast internet connection as it works terribly with slow connections and lags a lot.
Recommendations to others considering the product:
It helps you export spreadsheets into PDFs in secs and saves you all the effort and time you'd have to go through if you tried to do it manually. I totally recommend it.
What problems are you solving with the product? What benefits have you realized?
I personally use a lot and to solve many issues I go through with spreadsheets. I deal and work with spreadsheets very often be it for registration of events we organize in ASCE student chapter or for our technical work in construction filling in dimensions, quantities and/or areas. I would always face this problem when I have to export the spreadsheet in a PDF format as every time the pdf file ends up being incomplete and I lose a lot of my spreadsheet data because the spreadsheet has no size restriction as in PDF; Landscape A3 or Letter A4 sizes and even if it put all of the spreadsheet content in the PDF, the font size is becomes very small and unreadable. So I used this software ad ever since It became really super easy to export sheets into PDFs without losing any data and only with a few clicks.

Web based PDF signing tool I use PDFfiller for signing purchase orders or sending proposals for clients to digitally sign. It's great because users can sign documents in their browser without needing to download anything. PDFfiller's editing tools leave much to the imagination. I don't use the editing features as I can accomplish what I need with other programs.

The support team was incredibly responsive and helpful. They added 2 days of free access to my account, allowing me to continue using the service while the issue was being resolved. This gesture was very much appreciated and made a significant difference. Thank you for your excellent support!"

No Scanning! I'm just PDF Filling It makes capturing my customer's signature hassle-free as my business is online. No do-overs! Thank you! Because I make it mandatory for them to sign after placing an order. If they decide to change the order, within the specified time, they can sign to that too. What I like least about this software is that when actually filling in the blanks, the words do not align with the original text. This is an area that needs improvement.
