Easy-to-use program once you fiddle with it awhile. Would like ability to edit text also (portions that are inapplicable rather than striking through).

Works extremely well Super easy to figure out Very intuitive On the minus side I don't have enough PDFs monthly to justify the cost. Maybe there could be a 'per page cost' for the infrequent needs.

some good some bad cause need to change size of pics as my constant contact only takes jpeg. can't use your address book as i don't use my mac mail use verizon so not friendly with this stuff makes it harder to use overall.

I really like it. I have not read all of the instructions, but have used it on several forms. Would like to know how to print a form, without all of the background being printed. I mean, I upload a form. Fill it in and then try to print to the form that I have. It prints everything, when I just want to print what I filled in. For instance, had a problem with my QuickBooks. Wanted to print a check, quickly. Thought I will just upload a check, fill it in and print in on my check. It wanted to print everything. Of course, the bank will not take that, because if it just isn't quite right, it can look altered. Is there a way to do it? Of course, as you know everyone just wants to start working and not read the instructions. Thank you

Excellent!!! If this doesn't help you in today's busy office nothing will. I compare it to driving downtown. You know where you want to go but can't because of all the 1-way streets. It opens up all the roads.

As a landlord in a 2-family house, it's easy to create a lease. However, it's impossible to alter standard terms and conditions - this is a drawback.

pdfFiller is a Great pdfFiller is a great idea, "Not one software fits all." With so many different computer sources and digital platforms out there. We lose track what is compatible, what's not. Not using adobe frequently outside of work, this is amazing.

FAQs

If you can't find what you're looking for, please contact us anytime!
This is what makes the file so large: Excel is picking up a lot of empty cells and thinks there's data in them, which then it tries to save into the XLSX file on disk, and because it needs to keep references to all those hundreds or thousands of cells, the file size gets overblown.
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.
Switch to full or normal screen view in Excel To switch to full screen view, press CTRL+SHIFT+F1. To return to normal screen view, press CTRL+SHIFT+F1 again.
Compress the File (ZIP IT) Right-click on the Excel File. Hover your cursor on the Send to option. Click on the 'Compressed (zipped) folder' option.
Reduce the number of worksheets If you have worksheets with data that you're not using—and that don't contain any formulas you're using—delete them from the spreadsheet. The more data points you have in your workbook, the larger your file size will be. Removing unused data will reduce your file size.
Another reason for large file size is having many unused or hidden worksheets in your Workbook. Each Excel Worksheet has it's own share of metadata, more importantly, however, you may be keeping sheets with similar datasets, copies or unnecessary Pivot Tables that also take up a lot of space.
