Just started using the program today. Easy so far. A little problem with the aligment of fields. It would have been great to use the "tab" key to toggle between fields.

Easy to use, creates clean, professional looking documents, allows you to upload any form or document that needs to be filled out and fill it in as if you typed it, without needing the typewriter! Whether you scan a form, upload a text or spreadsheet document, even image files, you can fill in any information needed and customize fonts, size, color, highlight sections, even verified signatures and PDFfiller will align your input horizontally and vertically. You can even create templates of your forms. Easy to use intuitive interface. A definite value for the money.

It's makes working with PDF so easy. It does exactly what I need it to do with out the complications for using adobe pro. I am in real estate and this helps so much.

Loving the tool. It would be great if you could add an eye dropper feature so that if I alter text or numbers that are over a color background I can erase the copy fill in the area with the original background color and then revise the copy over the background fill

A thank you I was looking for options for a one off issue I had with PDF forms and signed up to PDF Filler for the 1 month free trial. I realised shortly after this that I would have little use for this facility in the future but neglected to cancel the subscription within the free trial period. At the conclusion of the free trial period I was billed for the annual subscription, however I contacted the company via Customer Services live chat and without much trouble they cancelled the subscription and refunded the fee. Excellent service and very professional advisors.

pdfFiller is a useful PDF editor and e-signing tool pdfFiller is a very easy tool to use if you find yourself needing to sign or edit PDF documents, but don't want to spend a lot of money on more expensive software. I appreciate how easy pdfFiller makes it to electronically sign documents or edit and convert PDF files. The instructions are easy to follow and within minutes you can merge, split or sign documents without to much effort. All in all I can't complain about the software. There were a few instances where I would download my signed document for it to turn out completely blank (in the free version), but then I'd just download it again and that usually solves the issue.

What do you like best? PDF Filler helped me when I inherited a bunch of learning material that referenced outdated case studies and I needed to update for class. Because I didn't have Adobe or photoshop, this was a great alternative to help me quickly update the decks. Erase text allowed me to "white out" the outdated information without compromising design quality. What do you dislike? If you are adding text and trying to use text box, it will show a box around what you replace. When using the text feature to replace text, of course, you won't have an exact match unless you know the current document's font and size. Nonetheless, PDF Filler makes it easy to drag, drop and align so that you'd have to really stare at the document to notice the differences between the original text and your replacement text. What problems are you solving with the product? What benefits have you realized? Needing to edit PDF's that were previously created, and provided no access to the original version. Better ease of use//less learning curve than Photoshop. Cost-friendly alternative to Adobe.

So far this program is a game changer. I wish it was cheaper (a discount for teachers on a year subscription would be wonderful!!) but I like what I am seeing so far;)
