Its a real good software, I think that people really can used it, maybe there should be a program that pay by used not a regular monthly charges. I am a every six month user.

It's probably just me but it's hard to figure out what does what.Also trying to figure out what I can move on a PDF and what I have to erase and fill-in again. Otherwise I think it's one of the best. I should also say seems be working with my Dragon NaturallySpeaking

There was one issue- the orange pen would pop up when highlighting a word or sentence, suggesting an edit I assume. I would click it then stare at a blue circle waiting waiting waiting. I would just close the entire website and come back.

I've been using PDFfiller regularly for over 2 years now, and it works wonderfully. I'm able to upload documents, add fillable lines, and get electronic signatures seamlessly. Customer service is also great - prompt and friendly in attending to any questions or issues. Makes running my business that much easier.

Many thanks to your "support" crew as I… Many thanks to your "support" crew as I found the first time through this in a long time is difficult to figure out. I will be filing this form on Monday so will let you know if we got it right!

Excellent Service I did the 30 day trial period and was very satisfied with the process.I used the product for about 10 different documents within a 2 day period. I forgot about the trial period and was charged for an annual subscription and was emailed the confirmation. I went online and requested to cancel the subscription due to not needing the product and received the cancellation with 5 minutes, very satisfied.

As good as DocuSign Allows you to create pdfs that with blanks in order to easily fill out. There are no free versions, so you pretty much just hope that a business has taken the proper steps to acquire this and utilize it.

What do you like best? The ability to upload documents as templates, to work on completed documents, whether changing page order or add/modify information. What do you dislike? I find it challenging to change fonts and text color. I'm not even sure it's possible. What problems are you solving with the product? What benefits have you realized? Simplification of creating clear, typed forms that elevate the professionalism of everythign we do.

A certificate stores the public key component of a digital ID. For more information about digital IDs, see Digital IDs. When you secure a PDF using a certificate, you specify the recipients and define the file access level for each recipient or group.
On the Protect tab, in the Certify Document group, click Certify. On the Certify Profile Wizard, choose the actions you want to permit from the Permitted actions list. Click Next. Select a digital ID to certify with, and choose whether to make the certificate visible. Click Next.

An electronic signature, on the other hand, is merely an image of your signature overlaid on top of a PDF document. You can do it with all kinds of apps, and it's what most people will require when they send you a document to sign. Send them a PDF file with a digital signature, and they won't know what to make of it.
