Free online tools for testing and securing your PC

Free browser tools from gHacks to test your devices, create strong passwords, count words, scan QR codes and check your IP address. No account needed.

gHacks tools are free utilities that run in your browser. Test your webcam, microphone and keyboard, black out your screen, generate a strong password, count words or scan a QR code, with no account and nothing to install.

The privacy promise is simple: what you type, record or scan is processed on your device, never uploaded and never stored, and every tool states on its page what, if anything, leaves the device. IP lookup is the one exception by design: it asks the gHacks server for the address your connection uses, because only a server can see it. Every tool is built and reviewed by the gHacks editorial team, which has covered PC software since 2005.

Passwords and security

The password generator creates random passwords of 8 to 64 characters in your browser with the Web Crypto API, and shows the entropy in bits plus an estimated crack time for each result.

Device tests

Device tests check whether your webcam, microphone, keyboard and display work, and show what each device reports to the browser. The camera and microphone open only after you click to start, and video and audio never leave your device.

  • Black Screen

    Turn your screen pure black, with timer and keep-awake.

  • Mic Test

    Check your microphone level, noise and playback in your browser.

  • Webcam Test

    Check your camera: live preview, real resolution and frame rate.

Text and QR codes

The word counter counts words, characters, sentences and reading time as you type, and the QR code scanner decodes codes from your camera or an image and flags risky links before you open them.

  • QR Code Scanner

    Scan QR codes from camera or screenshot and check links safely.

  • Word Counter

    Count words, characters and reading time in your browser.

Network and IP

IP lookup shows the public IP address your connection uses right now, IPv4 or IPv6, with an approximate country and a plain explanation of what the address reveals. The result comes from the gHacks server, with no third party involved.
