I completed a passport application. The document was easy to fill & very professional in quality which made it very easy to be understood during processing.

In grad school, much of my reading comes from pdf files my professors post. Prior to PDFfiller, I would print out hundreds of papers in order to annotate. Now, I can annotate while conserving resources and I have access to the files no matter where or what device I use.

It is easy to use and very helpful. I just started so I am a bit slow in getting the documents made or using it. I would have liked it a bit more straightforward, but I like it so far.

What do you like best?
I like the fact that live Customer service is always there to guide you if there's a problem.
What do you dislike?
The only thing I dislike if when a large corporation wants a form filled out and you use PDF Filler they come back and tell you their shop uses Adobe Acrobat and to please fill out the form once again using Adobe.

Fast, helpful assistance from their support team I forgot to cancel my subscription with them. The money came out unexpectedly, and I was honestly pretty worried because it was the full year's subscription and I have had issues with internet companies not wanting to refund subscription fees in the past even when I asked for it immediately, without using it during the period I asked for the refund for. PDFFiller was great, though. I emailed them early this morning (late for me) and woke up to their response, which was that since it was less than 24 hours after the payment came out, they were able to just void the transaction. Assuming my bank is cool about it, I'll have my money back today.5/5 Do trust.

What do you like best? The customer service was the best I have experienced . Very fast solutions to my questions and overall very nice system support along with billing support What do you dislike? The most amount of pages you used to be able to merge was five but they have since changed this so I have no dislikes with the product What problems are you solving with the product? What benefits have you realized? I used it to fill out contracts and pay applications along with notarized documents with my commercial construction company

organization I wish the updates had an option to keep the title and not make duplicates. I like to keep "my documents" organized and not all the downloads unless I want to save it as multiple copies. I love that it combines pdfs w other docs. I love the highlight and annotate features.

Ways to Reduce Excel File Size Remove unnecessary worksheets, data, and formulas. The number of worksheets and the amount of data contained in an Excel file are directly related to the size of the file. Remove formatting. Remove Pivot Cache. Save in binary format (. Compress the file.
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.
Remove unnecessary images, formatting and macros. Save the file as a recent Word version. Reduce the file size of the images before they are added to the document. If it is still too large, save the file as a PDF.
