What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
You have to carefully choose where to type, the format functions are limited and the printing is a little awkward as you cannot alter the margins. However, it is easy to use.

i am very surprised at how easy it is to retrieve and add new pdf's to my account. I originally paid for pdfiller because i wanted to send in a release of liability to the dmv. 1 year later and I am now using it for court paper work and have downloaded many forms i can fill out any time I want. Thanks. I am very happy and surprised at this application. I am glad i didn't cancel my monthly payments to pdfiller.

I first tried PDFfiller with a trial subscription and to be honest, I really just wanted it so I could add text to a document and I didn't plan to extend my subscription. But after trying it, I liked it so much, I continued the subscription after the trial and my subscription expires in 2 days and I plan to renew for another year. I'm a freelance paralegal and often need to add text (and complete forms) in .pdf format. The program is also very easy to use and has many great features (like "erase" and different font styles and sizes). My subscription has more than paid for itself and I would - and do - highly recommend PDFfiller to anyone looking for this type of program.

I have used PDFfiller to fill out PDF forms which wow dave required my either purchasing a piece of software or otherwise some other form of complex document manipulation - PDFfiller has made PDF document handling a breeze for me.

Wish there was a way to make all fields NOT-required, and add the required feature to the one I want, rather than undoing. Also, wish there was a way for the app to add fields where they seem to belong.

What do you like best? I love that I can fax items as well as the W-2/1099 features that are integrated into the IRS system! It makes my roles as a small business owner much easier with these tools. What do you dislike? I wish more features, such as sending documents for signatures, were added. Even just 1-2 documents a month would be helpful for my small business. A fax number included would also be helpful. I have been able to get a fax number for virtual faxing for much cheaper elsewhere. It would be nice to have an all in one for less than $25 a month or so. Recommendations to others considering the product: Great way to keep costs low while still running with the bigger companies and their larger budgets. From creating my own documents to faxing things for clients- great investment for virtual tools in your business! What problems are you solving with the product? What benefits have you realized? The IRS integration have helped me navigate some of the tax paperwork I need to do for my employees. The fax feature is super helpful for getting paperwork out for our clients.

Fast Refund! I was charged the $199 yearly subscription when I had forgotten to cancel due to personal reasons. The customer support agent quickly and easily handled cancellation and the refund. Thank you guys!!

I really like the capability of downloading forms, completing them and signing to send off. I wish I did not have to log in each time. That would be a great plus as I work for several clients and need the quick ability to do a form and send to them. Thank you Alice

Excel contains over one million rows – 1,048,576 to be exact.Here's how to do it. Navigate to Data >> Get & Transform Data >> From File >> From Text/CSV and import the CSV file. After a while, you are going to get a window with the file preview. Click the little triangle next to the load button.

Limiting Scroll Area Right-click the sheet tab for the sheet on which you want to place a limit. In the resulting Context menu, choose View Code. If the Properties window is not visible, press F4. In the Properties Window, place the insertion point in the box to the right of the Scroll Area property.
A good way to reduce your Excel file size is to get rid of the empty rows and columns. Here's how to do that: Select all unused rows and columns (Shortcut = Ctrl+Shift+Right/Down Arrow) Right-click > Delete.
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.
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.
