how to edit a scanned file to make it smaller
There are many ways in which you can make scanned documents smaller. You can do this by choosing the right format while the scanned document is being saved. For instance, when you scan images, you can save it in JPG format in a resolution which you prefer.
When documents are scanned, their size varies depending on the scan settings that you use. This might sometimes result in the output being too large. To make such scanned documents smaller, you can convert the scanned file into PDF format. This reduces the size of the document to a great extent.
