Basically a good PDF editor, the one failing is that formatting is not preserved during cut and paste. Could not get the correct formatting with the tools in PDFfiller.

I really like PDFfiller and it really easy to use. My only suggestion would be that you offer some way to delete or erase Fillable Names etc. that are saved if we choose. (i.e. Wrong spellings or no longer needed information.)

I lost all my forms that I filled out. I have to get blanks and start over. I'am not compurter literate. I could not retrieve my filled forms. What a waste of my time, No body bothered to let me know how l could retreve them. Only worried about what grade they would get.

Everything is wonderful Everything is wonderful, however with my bad eyes and being slow, i still say it is great.Sometime I have a little trouble moving from are moving to the area to get going to the PDF. It is not you it is me just a little slow. Can not see that good. I am good enough to get my job done.

Are you one that needs to easily sign documents and return by email? this is the software to use None I really liked how the software navigates you through the document so quickly so you don't forget to fill in any information, and it tells you if the recipient receives it. It's supposed to have just about any document you would need or want but I couldn't find any of the ones I needed. It was frustrating trying to look for a document and not be able to figure out where the list was.

several clunky features There are several clunky features I did not like. (1) My first issue was that when editing text, the font would change from Times New Roman to Arial within the edit box. The user had to "tell" the computer to switch back to Times New Roman. (2) Another issue I spotted is that if I want to italicize ONE word on a line of text, the entire line will become italicized. This was cured by deleting the italicized word, then creating a separate text box with the italicized word in it. The italic text box was dropped into the line of text with the plain text around it. (3) When editing text, the size of text will drop down a size or two. The writer must "bump" up the text size with the upward arrow to get it to match the text in the original document. Otherwise, I like using PDFfiller. Of course, PDF editing is not as simple as ordinary word editing. Or perhaps PDF editing gets easier after continual practice.

Must Have! This program is awesome for creating new contracts or clients, you can even email it and have them sign online. It automatically charges you for a year so make sure you choose monthly billing if you would like to be billed differently than annual.

Just like last year! I must file my church's taxes for our employees every year. I found this site last year. I love it! I prints the information I need. I can make copies and send it. I could send directly to IRS but chose not to do that route!!

organization I wish the updates had an option to keep the title and not make duplicates. I like to keep "my documents" organized and not all the downloads unless I want to save it as multiple copies. I love that it combines pdfs w other docs. I love the highlight and annotate features.

Why pdfFiller is a better alternative to your current PDF editor

When you choose a PDF editing platform for business and personal needs, you must choose one that allows to create, edit, share and convert PDF files fast. You'll need to convert dozens of files of various formats into PDF and vice versa, which means your solution should do so without any quality loss. It is a fact that this functionality has already been widely represented on the market. But what qualities really win the hearts of users?

Although every individual is judging PDF editors by how good are they at, actually, editing PDF files, nowadays, it's just not enough. From document creation to putting a digital signature on it, you need a solution that does it all in a single browser tab.

pdfFiller is a browser-based tool that gives you access to every feature you need for your PDFs from any device, whether desktop or mobile. It securely saves your forms to the cloud, so it's possible to get back to the previous version of your form whenever you need to.

pdfFiller subscription comes with many features, such as:

05
