Great service! Could use some updates though. The site is rather slow at times, and when changes text size there seems to be a bug where the page needs to refresh or reload. Also, general improvements on loading time would be nice. Also, please make the process of saving to PDF less steps and less clunky. I don't need to be shown where the pdf will be once downloaded.

Would prefer that it not open docs when I load them so that I can upload multiple docs without having to go back to "my documents" so often.

fantastic Pdf Editor. I have been using PDFfiller for a while now and its very easy to use. its highly eeffective to modify and edit all your document. very fast and a time saver. My only problem is that sometimes slows down when uploading a large file. but when that is done the rest works like magic. if you haven't tried this yet then you missing out. what an easy way to edit all your documents. i urge you to just try it. you will never regret it.

Look no further than pdfFiller! As a person 70+ years old, new programs are usually a challenge for me. However this was not the case with pdfFiller, it was so easy to click on the area and type and being able to alter the text size to fit was a bonus. I highly recommend this program and can vouch for customer support who are there to help.

Bravo! I was just on the phone and wrote back to congratulate the customer service rep on my call. I was very nervous about making sure my document was sent properly because a 5 year deal is riding on it. She helped calm me and understand things were handled properly. Bravo!
