It is a little hard to figure out how to size and arrange the words so they will all appear on the printed document. I had to redo this several times.

I found that access to and filling out of standard forms was very easy. I liked that editing and saving was also easy. Being able to log on and access your work from anywhere is a bonus

I preveiously gave the program a low rating before technicians showed me that my problem was user error. I find PDFfiller a great addition to my daily work. I can fill the forms in and also go back and edit. Love it!

No hassle customer service
I accidentally ordered this product, but I have no need of it. I requested a refund and received it immediately with courtesy and absolutely no hassle. If the product is as good as the customer service, you will have a good experience here.

Awesome software!
Very easy to use and great to help fill PDF's and create them. I use this software very often and I rarely have issues.
Sometimes it lags and it can be a pain, but overall this is a great software to use and I don't have many cons.

Easy to use!
Easy to upload files and edit them. Can add text, check boxes and even add wet signatures. All files kept in one place and can be easily downloaded back to my documents once edited!

It could be a little better if you put hints on tools that explained how to set and adjust them, but only if the person hovers over the tool without clicking it.

What does signing an assembly mean?
When signed, the name, version number and other assembly details are encoded using the keys to generate a hash value or cryptographic digest. When a signed assembly is loaded on the end user's system, the validity of the digest is checked using a similar process.
What is Assembly signing?
Assembly manifests are hashed and signed with a private key. The public key is by design incorporated into the assembly when it is signed, so your clients can verify the strong name. A. NET Framework SDK utility, the Strong Name tool (Sn.exe), is used to build strong-name key files.
What is a strong name assembly?
A strong name consists of the assembly's identity its simple text name, version number, and culture information (if provided)plus a public key and a digital signature. A strong-named assembly can only use types from other strong-named assemblies.
What is delay signing an assembly in net?
Delay signing is a technique for signing assemblies outside the build process. A delay signed assembly is marked with a blank strong-name key: it basically reserves space for the key to be added later, by an authorized user.
How do I know if assembly is signed?
To detect whether the assembly file is signed or not, right-click on the file and click the 'Properties' from the context menu. If you see a 'Digital Signatures' tab in the properties window, that means, the file is signed by a digital signature (as shown below).
