What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Excellent tool, but the only negative about this is. You should have highlighted that this is not free at the very beginning of the process. initially it says free trial, but when i complete the form & try to save or print or do anything can be done only post enrollment & paying. this is not fair & is misleading. Try to change this alone pls

I just started to use PDFfiller and like the ease of completing pdfs, and logical flow of the app! Also love the send fax feature although while it seemed to work well from the desktop app, it seemed to hang when faxing from my galaxy Note 4 (just kept spinning and I had to force stop the app)-- will have to try faxing more to see if it was a device or app issue.

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.

Useful for filling out applications. Its been so useful for applications that I'd otherwise have to write by hand. I have arthritis and writing information in tiny spaces is painful and there's never enough room for the answer. This has solved this problem.

To make the column or row expand itself to whatever the biggest cell is, double-click on the right of the column or row. To expand or shrink the row yourself, click on the line after the column or row that you want to resize and drag it up/down or left/right.
To make the column or row expand itself to whatever the biggest cell is, double-click on the right of the column or row. To expand or shrink the row yourself, click on the line after the column or row that you want to resize and drag it up/down or left/right.
For example, there is no simple and direct way to change cell width without affecting the whole column. While it's easy to change the width a column, the only way to adjust Excel cell width for one cell and not the rest of the column is to merge the cell with one next to it.
Generally, every cell in a row or column has the same size, so you can't adjust the size of a cell individually without affecting the others in its same row or column. You can merge adjacent cells to create larger compound cells, however, and you can set rows and columns to automatically adjust to fit text.
Cells > Format > (Column Width or Autofit Column Width or Default Width) Double-clicking on a Right-Hand-Side line between 2 columns. In Image below, if we Double-Click on a line between A and B then it will set the width of Column A to fit the widest value in that column.
