Yes, a scanned copy can be edited but it depends on the type of file and the software being used.
If you have a scanned copy in a PDF format, you can edit it using Adobe Acrobat software. You can add, delete or modify text, images, and even whole pages. Additionally, there are other PDF editors available on the internet for free or at a cost, and they all can offer the same PDF editing features.
However, if you have a scanned copy in an image format such as JPEG or PNG, you will need to use an image editing software such as Adobe Photoshop. The process is a bit more complex here as you will have to use Optical Character Recognition (OCR) technology to convert the scanned text into actual text that can be edited. Once the text has been converted, you can make the changes you want.
It is important to note that editing a scanned copy may result in a loss of quality, so it is advisable to make a copy of the original document before making any edits. Furthermore, the accuracy of the OCR technology is not perfect, and may result in mistakes or errors. So, it's a good idea to double-check the edited copy.
In summary, scanned copies can be edited, but it depends on the format of the file and the software being used. PDF files can easily be edited using Adobe Acrobat or other PDF editors, while image files such as JPEG or PNG, require an image editing software like Adobe Photoshop, and the process involves OCR technology to convert scanned text into editable text.
