This is an excellent tool to use to complete paperwork to save and email or fax back on the fly. You can print afterward, or as soon as you complete your paperwork. Saves so much time, and paper, as you don't have to print.complete.scan and then send.

The forms are very easy to fill out. I was unable to comments in a few places where I ran out of room for heirs and needed to include a comment to refer to an additional page.

I am happy with PDFfiller for the most part. It is a very good editor that makes a normal document look sophisticated. My only complaint is the price. 15$ a month for this? I mean it is a good editor, but 175$ a year is to much for me. Overall, it is a great app for editing with a great package of fun.

An easy to use program, great features, that allows you to complete and edit PDF forms. I'm no computer expert, but found this program straight forward to follow. Makes completing forms online so much easier than printing onto paper and filling out the long way. Would highly recommend it.

Made filling out forms easy without the hassle of physically filling anything out and submitting to places in person. I can just email whatever documents I make from pdffiller directly to where I need. Thanks, PDFfiller!

This is amazing! It is simple to edit a PDF document and also has so many other option to use. I was just going to do the trial, but now I will be subscribing to this service.

Life made easy If you fill a lot of forms, it is worth it. Otherwise you might not want to pay for the subscription for just one form. It makes editing and filling out forms so quick. The tools are great and the UI is easy to use and clean to look at. Once you fill the form, you have to pay or else you cannot save or print. This is not made clear from the start.

Convenient, Easy, and Potentially Free! I edit a lot (A LOT) of PDF documents. I love that I can edit, fill, sign from anywhere - on the go, on my phone, in the car, in the hotel. I can get it done and quickly. One of my most used tools hands down. I would like to see the website redesigned to be slightly more user friendly.

Michael Brown Search Engine Optimization: What is the optimal PDF file size for a website? The short answer to this question is small. I suggest no more than 1,024kb. Google prefers that PDFs be rendered, indexed, and ranked similar to what it is done with websites.

Answer: To optimize a PDF usually means to reduce the size of the files so that they are more optimal for Internet use. If you work with PDF files, there is a good chance this will be useful to you. By shrinking the size of the file, you can now send the PDFs as email attachments or even a bulk of them.
Locate the PDF file you want to make smaller. Click on and hold the PDF file. Drag the PDF file to the Drop PDF here icon on the screen. The file will upload and begin compressing. Scroll down and click on Download File Now. ... Select the location where you'd like to save the file. Click on Save.
