What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Customer support was top notch. They resolved my print issues with my form. The reason I did not give it 5 stars and would not recommend is that I Googled for a form to fill out for a US Passport. I didn't expect to find one i could fill in on line. What was not apparent was that ONLY AFTER SPENDING 30 MINUTES FILLING OUT THE FORM did I find out I had to pay $20 to print, save, fax, email or share the form. Customer service was great, but did not want to sign up for a monthly pdf service or pay $20 for 1 form.

It is a very easy way to fill out your form, however I did have difficulty retrieving my document after signing up. I contacted the customer service which gave a different website to use.

It was really easy to modify the text but it didn't allow for modifying the form itself. When I ran out of blocks (Employee Review Form), I couldn't add any lines to the bottom or even take away some of the "Reviewer comments" to give me space to add more lines for categories.

Slick tool. Nice editing capabilities. Some of the menus are confusing - for example: finding where to update an existing link to fill document is challenging.

What do you like best?
The support team is very helpful and responds quickly.
What do you dislike?
The product was excellent our company is too small to make proper use of their services. I would have appreciated being able to purchase the service to use on an as-need basis.
What problems are you solving with the product? What benefits have you realized?
This product allowed me to make pdf forms that could be filled out online/electronically rather than printed, manually filled out and scanned.

Very useful tool Useful app for managing all your pdf tasks. I always use this app to sign. Very recommended. It doesn't have many free features, you have to pay for the good ones.

Took me a while to figure out how to… Took me a while to figure out how to delete an entire page. My one suggestion would be to leave the previously used tool activated. I get tired of having to click on "eraser" when I'm trying to erase multiple blotches on a scanned article.

So far, I like it. If this app does as it looks so far, I can cancel 2 subscriptions for a pdf editor and digital signature app. This will consolidate our work into 1 location. I'm still learning the app but so far, I like it.
