NAPS2 Modern is a free, open source document scanning app for Windows 11. It scans from WIA, TWAIN, and eSCL scanners, then saves to PDF, searchable PDF, TIFF, JPEG, or PNG. It is an unofficial fork of NAPS2 (Not Another PDF Scanner) that keeps the same scanning engine and adds a redesigned Fluent interface built with WPF and .NET 10.
- Scan from most scanners: WIA and TWAIN drivers, plus eSCL for network scanners
- Save your way: PDF, TIFF, JPEG, and PNG
- Make PDFs searchable: optical character recognition (OCR) with Tesseract
- Organize pages: reorder, rotate, and edit pages before saving, and print or email the result
- Reuse your settings: scanner profiles, batch scanning, and auto save
- Windows 11 design: Fluent icons, Mica, your system accent color, and light and dark themes
- Screen reader names: pages and toolbar dropdowns have meaningful accessible names

NAPS2 Modern is based on NAPS2 8.6.0.
- Download the
win-x64zip from the latest release. - Extract it to a folder you can write to, because your settings are saved there.
- Run
NAPS2.Portable.exe.
There's nothing to install, and you don't need to install .NET.
The builds aren't code signed yet, so Windows SmartScreen may warn you the first time. To continue, select More info, then Run anyway.
For a good quality document scan, set your profile to 300 dpi and your paper size. New profiles can start lower.
You need Windows and the .NET 10 SDK.
git clone -b feat/modern-ui https://github.com/nelitow/naps2.gitcd naps2dotnet build NAPS2.App.Wpf -c ReleaseThen run NAPS2.App.Wpf\bin\Release\net10.0-windows\win-x64\NAPS2.exe.
Yes. It costs nothing and is licensed under the GNU GPL 2.0 or later, the same as NAPS2. The full source code is in this repository.
Yes, as long as Windows can see the scanner. NAPS2 Modern scans through the scanner's standard WIA or TWAIN driver, or over the network with eSCL, so it doesn't need the manufacturer's scanning app. A USB scan was tested on an HP DeskJet 2600 using WIA.
No. Scanning doesn't ask for your location or an account. A search of the source code finds no location APIs and no telemetry libraries. Connecting a Gmail or Outlook account is only for the optional email feature.
Yes, scanning and saving work without an internet connection. It only goes online for things like downloading OCR language files, or checking for updates if you turn that on. The update check currently looks for official NAPS2 releases.
Any scanner with a WIA or TWAIN driver, and network scanners that support eSCL. That covers many models from brands such as HP, Canon, Epson, and Brother, but this fork has only been tested with the HP DeskJet 2600.
It has been tested on Windows 11 x64. Other versions and Windows on Arm haven't been tested. Mica requires Windows 11.
This fork only changes the Windows interface. For macOS and Linux, use official NAPS2.
No. NAPS2 Modern is an independent fork and isn't affiliated with or endorsed by the NAPS2 project. Please report problems with this fork here, not to the NAPS2 developers.
The scanning engine, file handling, and most of the app come from NAPS2 by Ben Olden-Cooligan and its contributors. You can support the original project by donating to NAPS2.
NAPS2.Sdk is the scanning library from upstream NAPS2, supporting WIA, TWAIN, SANE, and eSCL scanners on Windows, Mac, and Linux.
