It's great. My kids have a lot of form for school that we have to print, sign, and then scan back into the computer. This prevents them (or me) from having to do this, great software!

Great pdf editing software PDF Filler is an awesome piece of software. It is so good being able to edit docs online and save them without having to worry about retyping information because the pdf provided was not able to be edited There is no version history which means if you make changes to the pdf you can backtrack to an earlier version unless it was saved separately
Travis K.
PDFfiller was easy to use. PDFfiller allowed me to edit and submit my application easily without much effort. PDFfiller allowed me to move the curser to start typing over the form questions. While this was not a hindrance it did take time to get the curser back to where it needed to be to complete the application. This small flaw was not enough to prevent me from using the application.

It served my purposes It served my purposes. There were a few instances where it would not properly let me check a box. Also, inputting dates, did not always work as expected. I was not always able to manually type in a date. It forced me to use the calendar. Sometimes. It's a good tool.
Elaine
I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.

This review is primarily for the customer service. This company had extremely quality customer service. FAST responses. I would definitely recommend trying it out for that alone, they will work through and address any issues you have. You won’t be disappointed. Great job.

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.
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.
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.
Excel has a used range for every sheet in your workbook. The larger this is, the bigger the file size becomes. Especially in older files, even if cells are blank and have no formatting, Excel may be treating them inside the used range, leading to a larger file size for no reason.
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.
