pdfFiller scores top ratings on review platforms
good solid editor-- would like to see other payment choices, like a quarterly option, and even instead of relying on automatic renewal, send a reminder email prior to the renewal to ensure the user is still consistently using product
Your guy was good - but I really didn't get the result from the program I expected. I thought it would convert to word exactly. I understand why it didn't - just makes the program less than what I had thought I was buying. I don't do this type of work often and will probably just discontinue the program.
It was easy to sign and save...
It was easy to sign and save my document with no interruptions or gemecs in between. I thought it would of been hard to get it sent via email but that was even more of a breeze.
Go to Tool for pdf Editing
Overall experience has been great ! This tool helps to merge, convert to pdf as well as edit pdfs as needed on the fly. The software has came in handy to sign documents electronically, quickly edit portions of pdf.
Great tool for editing pdfs. I mean you could edit very little detail in the pdf and you wouldn't even know if it was changed. All in one package that gives tremendous flexibility with converting word documents to pdf, editing scanned images by converting them to pdfs as well as getting and authorizing with ability to get electronic signatures. With this software you don't need Docu Sign !!
Cant erase back ground color for edited text. Edited text should appear seamless and not show signs of editing. Cursor movements and moving of text boxes needs alignment and calibration for more accuracy. There needs to be a way to revert back the changes done. Payment processing and charges need to be clear and upfront without any disguise.
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PDF Filler helped me when I inherited a bunch of learning material that referenced outdated case studies and I needed to update for class.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 Erase text allowed me to "white out" the outdated information without compromising design quality.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.
Great program. I want to especially compliment the customer service. Excellent! Resolved my issue within minutes - Ray was understanding and concise. I feel like good customer service is rare these days. Highly recommend PDF filler.
