What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
My only disappointment with PDFfiller was that I did not know it was a subscription based service since I clicked through a google link to a specific form. I made customer care aware of my concern and they were immediately responsive and apologetic fir the issue. Completing, saving, and printing the forms I needed was easy to learn and do.

Would like it if curser could "snap" to alignment, both vertical and horizontal, and then being able to maybe 'nudge' characters after typing using arrow keys. The red dashed line is very helpful, but getting things looking perfectly aligned takes careful precision with the mouse.

Very easy to use That I could fill it in immediately and be able to upload it and save it somewhere else. Also that the formatting remained the same That I had to save it twice in order to get what I had wrote. I also hate that the text box does not stay within the area you type in.

It's too early to comment. It's too early to comment about my experience. I started using this software today. Whatever I work I did today . with the software was a satisfactory. I need to try many other features and train myself using this software, before I can comment about my overall satisfaction.

I subscribed to the PDF filler app on… I subscribed to the PDF filler app on Google. And without asking me they charged me. Then I contacted them and they didn't want refund my money until I told them that I was going to let everybody know about their app.

It includes everything I needed to do, and then some. Its much more user friendly then even Adobe itself. But, for the price, and my specific needs, it works great.

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.
