NVDA Screen Reader Download for Windows – Free & Open‑Source Accessibility Software

NVDA (NonVisual Desktop Access) is a powerful, open‑source screen reader developed by NV Access, a non‑profit organization committed to making computing accessible. Designed specifically for visually impaired and blind users, NVDA converts on‑screen text and interface elements into speech and braille in real time, empowering users to operate Windows computers independently. Unlike expensive proprietary solutions, NVDA is free to download, install and use, making it one of the most popular assistive technologies worldwide.

NVDA’s commitment to openness extends to its GitHub repository, where developers and volunteers contribute to ongoing improvements. Whether you’re looking for a simple screen reader to navigate the web or need advanced accessibility tools for work, NVDA offers the flexibility and features to meet a wide range of needs.

What Is NVDA?

NVDA stands for NonVisual Desktop Access. It is a screen reader that allows users with no or limited vision to interact with their Windows PC using synthesized speech and braille displays. Developed in Python, NVDA’s architecture supports modular app modules, global plugins, and gestures that can be customized to suit individual preferences. The program runs on Windows XP through Windows 11, with ongoing updates keeping it compatible with the latest operating systems.

NVDA’s mission is clear: deliver a free screen reader that rivals premium products in functionality while promoting accessibility for everyone. The software has won multiple awards and is used by individuals, schools and organizations around the world.

Free Screen Reader for Windows

One of NVDA’s strongest selling points is that it is completely free and open‑source. You can download the latest version from the official NV Access website without registering or paying a license fee. NVDA is supported entirely through donations, grants and volunteer contributions. Users can also download a portable version that runs from a USB drive—ideal for use on shared or public computers without installation.

Because it’s open source, NVDA has no hidden costs and no unwanted adware bundled in the installer. This makes it a safe choice for schools, businesses, nonprofit organizations and individual users seeking a virus‑free screen reader.

Installing NVDA on Windows

Download & Installation

• Visit the NV Access website to download the NVDA installer. Choose the appropriate version for your Windows system (most modern PCs use 64‑bit).

• Run the installer (nvda_setup.exe) and follow the on‑screen prompts. The setup will guide you through language selection, voice settings and optional components.

• NVDA can be installed as a standard application or run in portable mode without modifying system files. The portable build is useful if you need NVDA on a work computer where you lack administrative privileges.

System Requirements

• Operating System: Windows 7, 8, 8.1, 10 or 11 (both 32‑bit and 64‑bit). Windows XP and Vista are no longer officially supported, but older releases are still available.

• Hardware: NVDA is lightweight; a modern dual‑core CPU and 1 GB of RAM are generally sufficient. It works well on laptops and low‑resource PCs.

• Storage: 100 MB free disk space for installation; less for the portable version.

Updates & Versions

NV Access releases major updates roughly twice per year, with interim point releases to fix bugs and improve compatibility. You can check for updates within NVDA or download new versions from the website. In‑place upgrades preserve your user settings.

Key Features of NVDA

Speech Synthesis & Voice Settings

NVDA includes eSpeak NG, a lightweight speech synthesizer supporting dozens of languages. Users can also install SAPI5 voices or third‑party synthesizers (e.g., Microsoft Speech API, Eloquence) to suit personal preferences. Speech options allow you to adjust rate, pitch, inflection, volume and punctuation levels for optimal comprehension.

Braille Support

NVDA integrates with more than 50 braille displays from manufacturers such as HIMS, Freedom Scientific, Alva and HumanWare. It supports USB and Bluetooth connections, UEB (Unified English Braille) and Nemeth math braille codes. Users can read text via braille and input commands using the braille keyboard. Braille output includes context information like focus and cursor position.

Object Navigation & Review Cursor

NVDA’s object navigation model lets users explore the Windows interface and web pages by traversing elements such as menus, dialogs and controls. The review cursor allows you to move independently of system focus to read text, examine status bars and review content without changing the active control. There are two modes of operation:

• Focus Mode: Sends keystrokes to the active application, useful for editing documents or typing emails.

• Browse Mode: Navigates web pages and documents using single‑key shortcuts to move through headings, links, tables, lists, landmarks and more.

Virtual Buffers & Web Browsing

When reading web pages, NVDA creates a virtual buffer—a flat representation of the page that allows quick navigation and reading. The screen reader works well with modern browsers like Firefox, Chrome and Edge, providing a rich set of commands to jump between headings, landmarks, form elements and tables. NVDA also supports Mathematical Markup Language (MathML) for reading equations via speech and braille.

Keyboard Shortcuts & Gestures

NVDA offers an extensive set of keyboard shortcuts to perform tasks quickly. Users can customize these commands or create new ones. For touch devices, NVDA supports gestures such as one‑finger and two‑finger swipes to navigate, activate and read content. This is especially useful on Windows tablets.

Add‑Ons & Customization

The NVDA community has developed numerous add‑ons that extend functionality. Popular add‑ons include:

• NVDA Remote Access: Provides remote control between computers running NVDA, enabling one user to assist another over the internet.

• OCR Support: Uses Windows OCR or third‑party engines to extract text from images and inaccessible PDFs.

• Extended Object Navigation: Adds features for exploring complex applications.

• Themes & UI Tweaks: Customizes NVDA’s interface, including dark mode and high‑contrast options.

• Scripting & Python: NVDA’s architecture allows developers to write scripts, app modules and global plugins to tailor behavior to specific applications.

Add‑ons are installed via NVDA’s Add‑on Manager and can be enabled or disabled individually. Developers can contribute via Python, and extensive API documentation and tutorials are available on GitHub.

Training & Documentation

NV Access provides a comprehensive User Guide, quick start tutorial and training materials. There are keyboard shortcut reference cards and audio tutorials available for free or purchase. NVDA offers certification and training courses for organizations that want to build accessibility skills. Online communities such as the NVDA forum, NV Access Blog, mailing lists, and Reddit offer peer support.

Language Support & Localization

NVDA is translated into more than 50 languages. Localization teams work continuously to keep translations up to date, making the software accessible globally. Users can switch languages on the fly or install additional language packs.

Secure Desktop & UAC Prompts

NVDA reads content at the Windows login screen and secure desktop (e.g., User Account Control prompts). This ensures continuous accessibility even when administrative privileges are required. Secure desktop support helps blind users install software and change system settings without assistance.

Audio & Visual Alerts

NVDA provides configurable audio cues and braille indicators to signal changes such as focus shifts, progress bars, errors or new dialogs. You can adjust the verbosity and choose whether to announce punctuation, layout, formatting and spelling mistakes.

Performance & Low Resource Usage

NVDA is recognized as a lightweight screen reader. It starts quickly, runs efficiently on older hardware and uses minimal system resources. This makes it ideal for netbooks, virtual machines and older laptops where heavy software like JAWS may slow down performance.

NVDA Add‑Ons and Development

The NVDA add‑on ecosystem allows users to customize their experience. Add‑ons can:

• Integrate OCR for text recognition in images and scanned PDFs.

• Provide additional braille display support or enhance existing drivers.

• Add touch gestures for tablets and convertible laptops.

• Implement scripts for specific applications (e.g., NVDA modules for Microsoft Office, Adobe Reader, Mozilla Thunderbird).

• Extend NVDA’s support for gaming accessibility through custom commands.

Developers interested in writing scripts can use Python for NVDA. The NVDA API includes classes for speech output, braille display control, input gesture handling, object navigation, UI Automation and more. Contributions are welcome through the NVDA GitHub repository, where bug reports, feature requests, pull requests and localization updates are managed.
