What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I am a self represented defendant in a small claims case. I cannot afford an attorney. With the robust capabilities, and plenty of time on my hands, I can plow through the case law and ca civil codes, but I can't readily find and fill out forms. PDFfiller has the forms I need and does a credible job of filling them out.

Easy to use It has made life much easier for my clients to receive what they need in a more timely manner Easy to upload specific documents for editing. When a field needs to be erased, the program always resets to add text. You have to re-select the erase button after each erased field.

Simple tool that increases productivity in office I'm a software engineer and have to deal with many documents everyday. Having a simple tool that has all the features needed for me to edit and handle all my documents makes my life easier. At the same time it saves me time to look up new tools and ways everyday. The UI is simple and intuitive, and it's easy to attach files, download and share it as needed. Overall it makes me more productive in office. My favourite feature is the electronic/digital signature feature. As a person in the IT department, I have to work with numerous documents and sign many of them. And this tool made that really easy for me. Also, the signature looks blended out and not out of place. Other than that the merging tool and conversion tool are also very helpful. Depending on my needs, sometimes I can convert a ppt into a pdf for easy access or for sending it to anyone. I also get to attach different pdfs together in whatever order needed. I don't have any major concerns. The only small problem I've had is regarding character recognition from scanned pdfs. Sometimes it is not entirely accurate. Though it is manageable for me.
