I use this to do my tenant leases
Overall, I have to have access to a software program like this. Some landlords issue leases on ancient old pdfs that are hard to work with. This program allows me to alter, merge, and arrange these in a fairly intuitive way. It took a minute for me to be comfortable with the document storage setup that pdffiller uses, but I am happy with it bc I can access these documents from anywhere!
I love the way you can just insert a text box, or erase. Wow its so nice to be able to do this with documents.
I find merging to be hard. I had to get help early one Sunday morning from support. The support was there and ready to instruct me. It just wasn't intuitive. I might even have to ask how to do it again.

To enhance the effectiveness of watermarks and passwords in your PDFs, ensure the watermark is prominent yet unobtrusive, blending well with your document's design. Use clear, bold text that conveys your brand message without compromising readability. When selecting a password, avoid common phrases and aim for at least 12 characters with a mix of letters, numbers, and symbols. Regularly update passwords and inform users of any changes, ideally using secure communications. This holistic approach maximizes your document's security and brand integrity.
