Can I make changes or add notes to the scanned documents?

Not directly onto the CD. CD’s are a read-only medium, which protects your images from being deleted or changed. You can annotate or otherwise edit Word documents once you copy them to your hard drive or other read/write media. However, only limited editing of PDF documents can be accomplished. PDF documents can be made password-secure upon your request. WeScanFiles can convert your digital media into a Word Document that you can save to your computer and edit as needed.
