Technical Specifications & System Requirements
Software notes
Features
- Works with virtually any scanner through TWAIN and WIA drivers, rescuing perfectly good hardware from abandoned vendor software.
- Built-in OCR in more than 100 languages produces genuinely searchable PDFs, not picture-only scans, at no cost.
- Saved scan profiles turn repeat jobs — receipts, contracts, ID cards — into one-click operations with the right DPI, color mode, and output every time.
- Handles automatic document feeders and duplex scanning properly, including blank-page skipping and page reordering for big digitizing jobs.
- Free and open source with no ads, no watermarks, no scan limits, and a portable version for shared or locked-down machines.
Considerations
- The interface is functional rather than polished, and first-time users must spend a few minutes learning profiles and driver selection.
- Image cleanup tools (despeckle, advanced deskew, background removal) are basic next to commercial scanning suites bundled with high-end hardware.
- When a vendor's TWAIN driver is buggy, NAPS2 cannot fully compensate — some cheap all-in-ones still misbehave with duplex or feeder modes.
About & Overview: NAPS2 for Windows PC
NAPS2 (Not Another PDF Scanner 2) is a free, open-source scanning application that turns any TWAIN or WIA scanner — including the all-in-one printer already on your desk — into a clean document-digitizing station. Scan pages to PDF, TIFF, JPEG, or PNG, reorder and rotate them, and run OCR in over 100 languages to produce searchable PDFs. It supports duplex and feeder scanning, saved profiles for one-click jobs (receipts at 200 dpi, contracts at 300 dpi with OCR), and batch scanning for archives. There are no ads, no watermarks, and no page limits; the project is donation-supported.
