What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It'd be helpful if there was a visual display on the side when selecting a document, so that I could see what I'm looking at and have the ability to rename it without completely opening it.

I took away one star because this is not an intuitive program at all. I have spent hours trying to figure out very simple tasks but once I figured it out it everything went very smothly.

What do you like best?
The ease of adding fields etc to current
What do you dislike?
Would like to visualize the entire page on screen.
What problems are you solving with the product? What benefits have you realized?

What do you like best?
This just helps a ton when I need to edit a pdf on my computer. I used to export PDFs as a jpeg and edited the photo and it was super stupid but this is perfect because I never have to try to remember how I edited a PDF the last time I did it.
What do you dislike?
It’s a little clumsy and took a bit for me to figure it out, which means I’m not excellent at explaining how to use it to other people that aren’t technologically inclined, but it still works really well.
What problems are you solving with the product? What benefits have you realized?
I need to edit release forms and vouchers on a daily basis for my models and it’s a breeze with this extension on my laptop.

pdfFiller for Easy Fillable PDF Files I am a 78-year-old with a partially paralized right hand. I started using this product to make fillable PDF files for English as a Second Language students I volunteer to teach online. With the instructions found on the site I was able to upload a five-page document and then add text boxes to the pages. I opted for the automatic text box creation, an extremely quick process, and only had to do some minor clean-up of extra text boxes. Overall, love the program.

At first I had difficulty understanding how to use PDF Filler maybe because the way the dashboard was set up was that there were too many icons that made it seem too overwhelming.

Great Customer Service I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named Anna was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)

So far so good. I like the friendly interface and the different options of sending processed files. I would like to request developers to incoporate "rotating page" for some documents that may be uploaded upside down
