What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I love this application! It has made my life so much easier in filing medical claims. I used to have to write or type them out (yes with a typewriter!) but now I just do them on PDFfiller and it takes me less than 1/2 the time! Thank you!

cool but needs a more user friendly interface. like small pdf for example. An easy converter option, with a file compress option would be cool. But as far as functionality and edit ability, PDF filler produces superior edits and is why I choose it over other products.

What do you like best?
PDFFILLER has been one of the best platforms I’ve used in client document transmission. The price is unmatched for the services available and the HIPAA compliance seals the deal.
What do you dislike?
The only downside is how long some forms such as registration can take to complete when adding in the initial fillable fields.
What problems are you solving with the product? What benefits have you realized?
Many of my clients are throughout the country, so the ease of securely transmitting documents while maintaining HIPAA compliance is the best problem solved. I recently discovered the ability to have documents faxed digitally through the services and it’s cut down on my physical paperwork.

Convenient and easy tool!
I've used pdfFiller since 2016. Easy to use, and has been great for converting, editing and merging documents and forms. I love that unlike programs like Adobe Acrobat I can access and use pdfFiller from anywhere. It has been convenient for work and home use. Had to convert and digitally sign legal documents from Word to PDF today and no one involved had any suitable programs, but I had the solution with pdfFiller!

PDFfiller is the best app ive found so far for editing and creating fillable forms. I've tried one which is very inferior to it. Definetly gets the job done. Would recommend to anyone.

What do you like best?
I love how I can neatly complete compliance filings that don't have a fillable PDF format using PDF filler. I can type on the form in PDF filler instead of having to print a hard copy and hand write or use a typewriter - who even has access to one of those anymore, lol?
What do you dislike?
It can be tricky to get the alignment just right and then save the completed document.
Recommendations to others considering the product:
Great tool for using to complete documents that don't have fillable format.
What problems are you solving with the product? What benefits have you realized?
Completing compliance filings for various States that don't offer fillable PDF forms.

Very practical application that serves as a daily option when I don't have a printer readily available. Its become an essential part of my work flow, especially since it allows me to work from my computer without have to go out to send mail from the post office.

Why is my Excel file so large with little data?
It happens many times that we import data in Excel file for temporary use but forget to remove it. This increases the size of the Excel file. To reduce the size of Excel file identify the data that you don't really need. Delete those ranges and save the file.
What causes Excel file size to increase?
It is also possible that changes in any macros attached to the workbook could have greatly increased the file size. Finally, if you changed the format used to save the workbook, then the file size can increase. Check to make sure that you are using the proper file format for the version of Excel you are using.
