Free Scan to PDF is a tool that scans paper documents and converts them into PDF files.
The program has a modern and well-organized interface. All its options are clearly defined, making your work a lot easier. By using this application you can also import images and edit your files before the conversion. It allows you to change the zoom of the picture, rotate it and even crop an area. If you make a mistake, you can always use the 'Undo' or 'Redo' options, so you don’t have to worry about it. After you have finished editing the image, you can turn it into a PDF document with a single click. An advantage of converting images is that the program supports a huge variety of formats.
Another important aspect is that this software can also be used as a PDF previewer. It has all the basic options, such as 'Document properties', 'Zoom in & out', 'Fit Width', 'Fit height', 'Print', and etc. However, I think that a drag and drop feature could be more efficient.
In my opinion, the most interesting feature of this program is an ability to add passwords and digital signatures to a PDF file, so you can protect your privacy and your important documents. The application comes with a 'Remove Open Password', which removes the password you have already set.
I think this tool combines its previewing mode with its ability to scan and convert paper documents in a very organized way. You don’t need advanced knowledge to use it and it has lots of advantages. The best thing is that this application is free.
