What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Works great. I would have give a 5 stars if there's a way to copy and replicate the entire form. Also the ability to rename file name would be nice.

The system worked very nicely overall. I have uploaded several documents now and found it very nice for completing PDF and Pre-made fillable Word documents as well. I only had one minor glitch the first time I used it, but have not seen it repeated in several usages since. Overall I would definitely recommend this if you have to regularly fill and edit forms.

So far, I really like PDFfiller and have used it to edit several documents that I needed to revised for others but previously could only leave comments for users. Using PDFfiller has made me so much more productive.

Over all really helpful, especially with me filling out awards and scholarships for grade 12. Only issue I had was when typing the text box wouldn't fit as nicely as I would have liked it to, so lines ran through the text and made it a bit harder to read.
