What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Great. However, I need to type vertical on the forms I am filling out and am not sure PDFfiller allows this process. There are two pages that I prefer to print on one page but I do not see this option when I am ready to print.

Would like to have available stand-by the form I am working on. Have to use the same for different companies and each time I start a new one, have to go back and search for it.

What do you like best?
PDFfiller actually has lots of online tools that can help with many general document editing tasks. We can convert PDF files to lot of different document formats such as DOC files, which are files I use often at work. For document signing, editing and adding fillable fields is not complicated. The toolbar has tools that are neatly laid out and easy to access. There are lots of click-and-drag features that make using PDFfiller comfortable, even with hours of editing. There are also helpful collaboration options that let internal staff communicate about document edits.
What do you dislike?
From an admin perspective, it's been a delight working with PDFfiller, but some people that receive our digital documents can sometimes have trouble accessing the files and knowing how to sign them.
Recommendations to others considering the product:
PDFfiller can be a valuable solution if you need to make lots of edits to PDF files and don't have a much experience with more advanced software like Adobe Acrobat. It seems to be designed for beginner users, but can also work for more expert document editors.
What problems are you solving with the product? What benefits have you realized?
Even though I know how to use various popular PDF and document editing software, I often turn to PDFfiller to allow for more intuitive editing features and its abilities to work with just about any PDF we load into it. It's a versatile editing solution that lets us quickly format our documents to our specifications.

Great Value for the features included PDFfiller has all of the features I need. The ability to combine documents, fill forms and add signatures. Navigation is not intuitive and the user interface is cluttered.

Great way to electronically complete forms! I hate printing and re-uploading forms. This is a great way to eliminate that. Also good for converting static files to dynamic documents! It can be finicky and annoying to use if the computer doesn't have the right software.

This application solved my work! I am constantly receiving email with PDF attachments which I must review immediately and in many cases merit that I fill or edit them, for which I had to download the mail file and manipulate it to send it again. Well that I finish since discovering this extension for my mail, through it I open and edit online from my mail the file received. This speeds up the tasks. The only thing I should mention is that being an online job, the Internet connection must be constant and efficient so that the work flows quickly.

It was easy to navigate tools. It was easy to navigate tools. But I would suggest some additional edits for the photos such as free clockwise rotation when necessary

What do you like best? I love how easy it is to navigate. the User-functionality makes it very easy to use and know how to create new content. What do you dislike? I wish there was a more user friendly version in IOS or Android App Store. Recommendations to others considering the product: There is so much this Program can do. If you have the time, watch videos and contact the support team to ask questions about how to use this effectively. What problems are you solving with the product? What benefits have you realized? I have not had many problems because of how easy it is to use. I wish there were more payment options to choose from though.
