My experience Pryor to contact customer support via online chat wasn't a pleasant experience. However my representative went over and beyond in my opinion to resolve the issue for me. If customer support is this affect and expressed concern the way he did on a daily or frequent basis... then definitely purchase this product. Hands down.

I am unfamiliar with these programs and so I struggle. I was unable to increase the size of the text in one of my forms and it looks awkward on the form after printed.

I really liked the variable size eraser. I needed to send my bank statement out and I did not feel the party needed to know my balance when they were only looking for a particular debit.

Logging issue troubleshoot I was having issue logging into pdfFiller with the password that I remember, at the same time could not receive any email to reset my password. Harmhon, the live chat agent from pdfFiller, has patiently understand my situation. Although most of the time is user's issue that they don't check on junk mail or they have some instruction/rules listed in their setting. But Harmhon is able to figure that my email address was actually not being whitelisted in your company whitelist. That being said, after Harmhon inserted me into the whitelist, i am able to login without any issue again. I really appreciate Harmhon's patient and service. He is definitely a precious asset to pdfFiller! Keep up the good work!

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.

The biggest contributor to bloat is not actually the amount of data or the number of cells containing data on a sheet, but rather the size of the area of cells which Excel thinks are being used in some way. This is called the 'Used Range'.
Save in binary format (. xlsx or . xlsm) without specifying. Choosing the binary format (. xlsb) while saving the file can dramatically reduce the file size.
How to reduce JPEG file size on Windows Open the JPEG file with a double click or Right-click file > Open With > Photos. Click the three dots in the top right corner and select Resize. Choose the recommended settings or Define custome dimentions to resize the JPEG file manually.
