PDF Signer

PDF Signer is a simple-to-use software application designed to help you digitally sign multiple PDF documents at the same time.

It does not come equipped with complex features or configuration settings, making it accessible to all types of users, regardless of their level of experience.

The setup procedure does not take a long time to finish, nor require special attention from the user's behalf. As far as the interface is concerned, PDF Signer keeps it plain and simple, going for a standard window with a neatly organized structure.

You can digitally sign a single PDF document or an entire directory, point out the saving folder, mention a signing reason and location, select a digital certificate from the Windows Certificate Store or a PFX file, as well as pick the hash algorithm between SHA1, SHA256 and SHA512.

New certificates can be created on the Microsoft Certificate Store or on a password-protected PFX file by setting the name issued to, organization name, title, organizational unit, email address, validity period, along with RSA key and signature algorithms.

As far as the signature appearance is concerned, it is possible to tweak its position and font size, place an image on the signature box, and so on. Plus, you can apply a time stamp to the documents, as well as encrypt them to restrict the access of other users.

The tool does not put a strain on PC performance, as it runs on low CPU and RAM. We have not come across any issues throughout our evaluation, since PDF Signer did not hang, crash or pop up error messages. This app comes packed with rich options for digitally signing PDF docs in batch mode, catering to all user levels.
