I am delighted that I found this PDF filler own line. I tried Adobe; however, I could not understand how it works. This is simple and easy to use. It is not difficult to drag and drop a file and then begin to fill in the proper document.

Using this site to fill out divorce paperwork. Sometimes the text is too big for the field I'm in, but other than that I think that the site is awesome.

What do you dislike?
I do not dislike anything. If I had to pick my least favorite thing, I’d say that sharing documents via is not as straight forward from the website. I usually save a local copy and email from that to avoid confusion.

Wonderful and fast support team!
I was in need of this service and it worked seamlessly and has a lot of options during the free trial that I had access to. I was not in need of the 1-year subscription that I was charged for. I reached out to their support team when I saw the charge come through and they canceled my subscription as well as fully reversed the charge with no hassle at all. This is a very useful service for those who need to edit pdfs frequently! Anna from their support team did a wonderful job and was very pleasant to work with.

I've been very happy with this product!
I've been very happy with this product! It has helped me tremendously file insurance claims and do work since my husband has been in the hospital since 5/30/20. I did the free trial but will be purchasing it for the year.

Honesty and integrity are not something…
Honesty and integrity are not something I align with online trial subscription. Most will hope you forget so they can charge you anyway. But PDFfilIer holds to a higher standard. I am NOT an employee forced to write a review. This for real just happened like 10 minutes ago.
I signed up for a trial to complete a job for my employer. Forgot to cancel before the trial ended. I don't make much, so $96 was a hit I wasn't expecting or able to pay. Support had already approved and completed the refund and cancelation of my subscription before I had even finished explaining my situation to the rep in chat (Aiden). The email came from "Sarah from PDFfiller" explaining that it was taken care of while I was still chatting with the rep.
I was expecting a battle. Now I expect to either sign up with PDFfiller when I have a more consistent need or get my boss to pay for the service. The platform was quick and easy to navigate. Based solely on this experience, I would recommend this platform if you are in need of creating these types of documents.
The only thing I would change is that I couldn't find my payment options in my account info to see what card was used. Nor could I find an avenue to change my payment options.

How can I reduce my Excel file size?
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.
Why is my Excel file size suddenly so large?
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.
