pdfFiller scores top ratings on review platforms
The only problem I have is, if I highlight a word or group of words and I want to take it off, it is very difficult to undo. I spent 2.5 hours last night trying to do just so.
Everything has been great, with the exception that it takes a while to open up the documents on mybox. There should be a feature for ''QUICKVIEW" of the document you want to open.
I am so thankful for its many abilities. I am glad that I can skip the conversion to Microsoft Word first before I can fill the form or edit a document. It has saved a lot of time for me.
What do you like best?
Ability to use templates was the most helpful. I like PDF filler because I can encrypt and decrypt documents, merge PDF files, crop or rotate PDF pages. It's fairly easy to use but the interface isn't great.
What do you dislike?
The user interface is not intuitive for me. I liked all other features and don't have much bad to say. I'll continue to refer people.

It is the best website if you are working from home if you are an environment lover and want to save the earth by not printing paper and also save money.
What problems are you solving with the product? What benefits have you realized?
We are in the transportation business, so we have to send the documents for the Border clearance.
Earlier, we used to print the documents and then put a border sticker and write notes with a pen on it.
But, with the help of this, we are saving a lot of paper. Just upload the docs to pdffiller and copy, paste border sticker, and write notes with edit text icon. Everything is easy now.
