NAPS2

NAPS2 (Not Another PDF Scanner) is a free and open-source scanning application for Windows, Mac and Linux. It focuses on one job: getting paper documents from your scanner into clean PDF, TIFF, JPEG or PNG files with as few clicks as possible. Where the software bundled with printers often hides scanning behind accounts, upsells and cluttered menus, NAPS2 keeps one clear window: pick a profile, press Scan, save. It is the kind of tool you reach for when a stack of receipts, a signed contract or an old family document needs to become a file you can keep.

Works With the Scanner You Already Have

NAPS2 talks to scanners from Canon, Brother, HP, Epson, Fujitsu and many others. On Windows you can choose between WIA and TWAIN drivers, whichever behaves better with your device; on Linux it uses SANE, and it also supports driverless ESCL scanning. Flatbeds and automatic document feeders are both covered, including duplex scanning when your hardware allows it. Settings like DPI, page size and bit depth are saved as profiles, so the next batch of the same kind takes a single click.

Clean Up and Rearrange Pages

Once pages are scanned, drag and drop them into the order you need. The interleave tool is built for a common real-world case: scanning a two-sided document on a one-sided feeder, where you scan the fronts, flip the stack and let NAPS2 merge the pages in the right sequence. Pages can be rotated by hand or automatically deskewed, and simple image tools crop or adjust brightness and contrast before you save.

Searchable PDFs With OCR

NAPS2 includes optical character recognition based on Tesseract, in over 100 languages. Run OCR on a scanned contract or receipt and the resulting PDF carries a text layer: you can search inside it, copy passages out, and find the document months later by its content instead of its filename. For anyone digitizing a paper archive, this is what turns a folder of images into a usable library.

Built for Offices and Power Users

Behind the simple default window, NAPS2 offers an optional command-line interface for automation and scripting, an MSI installer with application-level configuration for group policy deployment, and portable builds that run without installation. Scanners can also be shared across a local network, so one USB scanner can serve a whole household or small office.

Things to Know Before You Rely on It

Results depend on your scanner's drivers: a device with poor WIA or TWAIN support may take some trial and error, and very old or exotic models can fall back to limited modes. OCR quality follows scan quality; a skewed, low-resolution scan of faint text will not recognize well. There is no built-in cloud storage integration, mobile app or account sync - files stay on your computer, which some will count as a feature. The interface is deliberately plain.
