I preveiously gave the program a low rating before technicians showed me that my problem was user error. I find PDFfiller a great addition to my daily work. I can fill the forms in and also go back and edit. Love it!

great customer service - sam great, easy to use, saves us a fortune on an extra phone line for a fax. Great customer service, I always use live chat and get answers and resolution within a few minutes. I have only had to use support 3 times in a year because the program is so user friendly.

PDFfiller is the best, hands down I've used just about every PDF filling service I can find and although PDFfiller is on the pricey side, I've found them to be the best because of their drawing features, beautifully organized website on both desktop and mobile, and super fast customer support. If you need to fill out PDF's regularly, I'd say PDFfiller at $6 per month is easily worth the money.

PDFFiller saved my books! PDFFiller saved my books! As a young author, I had no idea what I was doing and deleted my original documents once the books were published. I only kept the print-ready PDFs. Years later, I realized there were a lot of spelling mistakes and errors in them, and wanted to re-publish. Since the books had photos, I couldn't simply convert to a doc. Most PDF tools online didn't work, or put on watermarks. PDFFiller allowed me to edit the text in the PDFs, to correct the spelling mistakes, and merge the documents into one cohesive PDF again. I was able to republish an edited book without the original documents, thanks to PDFFiller. The one thing I missed that could make this a fantastic tool- the original book was 8.5x11. I wanted to republish at 6x9. I ended up having to resize it through a different tool, which simply shrunk everything instead of being able to directly resize the content. Due to that, the book appears much smaller on the pages than it should, and I've received some complaints that it's harder to read. If PDFFiller had a viable PDF resize tool that worked to resize the content versus simply shrinking the document, it would be a stellar addition to the repertoire.

Pleasant PDFiller! I use PDFfiller almost daily. I work in Accounts Receivable and customers frequently like to have additional information added to their invoice. This is something our accounting program cannot do. Very user friendly. Very appealing to look at. I don't have any cons. I haven't found anything that I don't like about it.

Filling in the pdf was great, however when I saved the file using "Save As" the text was not spaced out in the boxes but overwritten making it difficult to read.
