A must have!! This is a must have for anyone that uses PDF's alot. It can save you a ton of time. This software is awesome, I love that you can take any PDF and alter it. It is easy to use and comes in handy. I wish this software was more set up like Word, as in the features and where things are located. Some of the features are hard to find.

I usually do not leave reviews but this tool is sensational Ease of use, the functionality is greatly appreciated. Gliding through forms is of ease. Moving from box to box is a cinch The save feature to my computer can be a little friendlier. It can take several try to find the forms after I save them

If you have a lot of digital documents, you should use pdfFiller My overall experience is great! It's free and very easy to use, and I strongly recommend it for any student, teachers or professors, colleagues from work, and even for managers because during this pandemics, we all had to adapt our documents to digital format, and print them at home could be an issue for many people. I love to use this software because it's free and it allows me to sign digital documents from anyone in my company without having to print everything, sign it all, and then scan it, and e-mail it to the recipients. It's great because it has other checkmarks so you can add little details in case you are reading a contract or a file that needs reviewing. Positively, there are no cons for this software, as I have been using it for work and college matters, and it solves a great deal of signing important documents!

Could be worse! Cheap, handy, available on all my devices. Billing department works very fast and efficient. Glitches and crashes while I am doing offline editing. What do you think about this review?

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.

Combining two files was relatively easy once I read... Combining two files was relatively easy once I read the How to Guide three times to figure it out. But editing text in the file resulted in a change in the font that was not particularly satisfying and could not be corrected.

Secure URLs indicate that the information transmitted from the browser to the server is not able to be intercepted by hackers or other unwanted prying eyes. SSL certificates are most commonly used by online businesses and e-commerce websites that need to protect credit card details while processing transactions online.
Look at the URL of the website. If it begins with HTTPS instead of HTTP it means the site is secured using an SSL Certificate (the s stands for secure). SSL Certificates secure all of your data as it is passed from your browser to the website's server.
As the other answers have already pointed out, HTTPS “URLs” are indeed encrypted. However, your DNS request/response when resolving the domain name is probably not, and of course, if you were using a browser, your URLs might be recorded too. Entire request and response is encrypted, including URL.
1) A secure site builds your customers' trust And if you collect payments or give your customers the ability to log in to your site, a secure site is a must to make sure their passwords and other sensitive information stays safe. It's just the right thing to do in this day and age where digital security is paramount.
By default, every file/folder you store in OneDrive is marked private by default. As an alternative, you can invite others to access your OneDrive files by a specific invite that only they can use. This is one additional level of security for your files if you are concerned about shared links getting out in the wild.
You can use OneDrive to share photos, Microsoft Office documents, other files, and entire folders with people. The files and folders you store in OneDrive are private until you decide to share them, and you can see who a OneDrive file is shared with or stop sharing at any time.
