Start with your scanner and document
Check support for your installed WIA/TWAIN driver, the page size you use and any feeder or duplex requirements. These options depend on the device and driver.
Try a representative page
Collect one page, inspect clarity and page order, and save a PDF. Test the controls you need before preparing a larger document.
Choose by the task you need
Scanner acquisition, PDF editing, OCR and digital signing are different tasks. The current free scanning app focuses on acquisition, page arrangement and image-PDF output; use a tool that explicitly supports any additional task.
All included application features are 100% free. No registration or activation is required.
