very intuituve. quick and easy to learn. i operate mobily so i like the fact that i can use it on any of my 4 computers any where in the world. Very easy to drop text in. I like the erase and highlight feature. I tried at least 6 other platfroms and they were too dificult to use.

A little difficult navigating. There is no clear description of what some of the functions are. Would be helpful to maybe add a description as you hover over a button, or at least give a description of what the function does when you click on it.

I found it really easy to use, but all of the boxes did not have specific instructions. I struggled with boxes 16-18. Through google, I discovered that I should leave them blank.

Program great, easy to use. Difficulty processing payment. Had to call/email support to get assistance. That was super frustration when I was ready to finish up.

I've been a customer of ********************** for almost 2 years now. The program has completely upped my game from writing business letters, filling out pdfs, faxing important documents - there is no limit to what you can do with a program like PDFFiller. But, what really pulled me in, other than the superb professional look and quality that PDFFiller gives my correspondence, was the help I received when I needed it. For example, I needed help with merging two documents that I needed to fax. I received help via the Chat Box within seconds of asking for assistance. It's like having your own IT team 24 hours a day! I also just found out that outbound faxes are included in the price and, if you want your own inbound fax number, $20.00 a month gets you your own fax number! The list goes on and on. I can't say enough about PDFFiller! Complete professionalism, confidentiality, and customer oriented. Try **********************! You will not be disappointed!

I have never needed a pdf filler before… I have never needed a pdf filler before but this website has made everything super easy to understand and use.

What do you like best? I like that PDF Filler is user friendly and it's easy to navigate. I love that I can create a template and then just fill in what I need to for each customer and we can send them a form digitally for them to sign. What do you dislike? Occasionally customer's take a while to sign a document because they think it is spam. Recommendations to others considering the product: Easy to use program. Creat templates you can use over and over which is great! What problems are you solving with the product? What benefits have you realized? It's a fast, easy way to be able to send documents for our customers to sign without having to sign in person. We have also been able to streamline some of our processes better by using PDF Filler to create documents.

Having to make the check boxes into… Having to make the check boxes into check marks instead of x takes while when you have twenty on the page. It would be nice if you could decide for the whole page.

It happens many times that we import data in Excel file for temporary use but forget to remove it. This increases the size of the Excel file. To reduce the size of Excel file identify the data that you don't really need. Delete those ranges and save the file.
Do you want to know how to reduce your Excel file size? First, audit your large Excel file. Tip #1: Remove conditional formatting. Tip #2: Crop each worksheet to its used range. Tip #3: Remove unnecessary formulas. Tip #4: Compress pictures in Excel. Tip #5: Clear data formatting. Tip #6: Delete watches.
You can shrink or enlarge a worksheet for a better fit on printed pages. To do that, in Page Setup, click the window launcher button. Then, click Scaling > Adjust to, and then enter the percentage of the normal size that you want to use.
Right-click on the Excel File. Hover your cursor on the Send to option. Click on the 'Compressed (zipped) folder' option.
It is also possible that changes in any macros attached to the workbook could have greatly increased the file size. Finally, if you changed the format used to save the workbook, then the file size can increase. Check to make sure that you are using the proper file format for the version of Excel you are using.
