I like the online webpage. However, I have trouble using the app. It doesn't have my saved signatures and it won't link to my OneDrive (Office 365) properly.

It was difficult for me (86 years old and somewhat "ok" with Windows 10) to figure how to send the document to my partners vie email for their markup, etc.

PDF Filler is a must for me! I love it! As a small business owner who strives to maintain a professional business image (website, business cards, etc.) , PDFfiller does just that for the proposals I create for my customers ... both future, and repeat. I know for a fact my customers appreciate the quality and professionalism of the proposals they receive from me - they've told me so! Thanks PDFfiller! I love the ability to quickly, and easily, create/copy professional proposals for my customers. I then save each file as a PDF (with my logo embedded at the top left of each document), and attach via e-mail for completing my estimation process with each customer. The only thing I've discovered is with the particular template I use for my particular proposals - my template has an area that indicates "Page 1 of _" ... well, there are no additional pages that are affiliated with my template, so I end up either having to re-edit to ensure my entire proposal fits into "Page 1", or I have to continue additional pages outside of PDFfiller.

sometimes the app freezes and takes a few minutes to load which can be inconvenient when files are needed quickly. Also some features also drag for example the signature portion. Overall great app which I use daily for my work.
