What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Easy to use, a little misleading on the web site "try for free" and then it wants to charge me to save / print, but live chat was quick and the chat agent (Anne) was awesome and provided me a 7 day free trial so I can see if this will be worth the subscription. Hats off to the chat agent, awesome customer service, GIVE her a RAISE! LOL

Really good, not sure how I would be at editing large amounts of info on a PDF with the website but I could be surprised if I went through the online training.

Two main issues I have with PDF:
1) not being able to change the names on the forms,
2) easily finding a form to download to My Forms (referring to Acord forms mainly, you would think your company would have a direct link to Acord forms draw from)

Seems user friendly for the most part. It would be nice if the documents could be automatically opened in Drive without all of the signing in process each time

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 .

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.

Multiples fonctionnalités, facile et pratique d'utilisation, surtout pour les formulaires
Que la période de gratuité soit comme telle, il faut que ça soit effectivement gratuit

Great communication and customer service!
I haven’t used their service but I was being charged yearly by mistake for whatever weird reason, and they immediately gave me a refund and apologized. These guys are on the ball! Couldn’t complain if I tried.

working great so far, any difficulties are due to my lack of knowledge. My only suggestion is to hire one really dumb guy, and make it so its easy for him. Would you like me to send my resume'?

Why is my Excel file size suddenly so large?
This is what makes the file so large: Excel is picking up a lot of empty cells and thinks there's data in them, which then it tries to save into the XLSX file on disk, and because it needs to keep references to all those hundreds or thousands of cells, the file size gets overblown.
