I preveiously gave the program a low rating before technicians showed me that my problem was user error. I find PDFfiller a great addition to my daily work. I can fill the forms in and also go back and edit. Love it!

Great Value for the features included PDFfiller has all of the features I need. The ability to combine documents, fill forms and add signatures. Navigation is not intuitive and the user interface is cluttered.

Easy to use Easy to use. I wish I came across this solution first because with it I was able to do in 10 minutes what I couldn't do in hours with the other editors I tried, not counting all the time trying to find them.

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.
Choose File > Print. From the Page Scaling pop-up menu, select one of the following options: Fit To Printable Area Scales small pages up and large pages down to fit the paper. ... Click OK or Print.
