PS Controller Calibration

Calibrate PS5 DualSense and PS4 DualShock 4 analog sticks using WebHID hardware access. Recalibrate resting center zero-points online free.

Connect PS5 DualSense or PS4 DualShock 4 via USB to enable WebHID calibration...

No WebHID Controller Connected

STEP 1

Connect WebHID Mode

Click below to request direct USB WebHID hardware access to your PlayStation controller.

STEP 2

Center Sticks Zero-Point

Let both analog sticks rest naturally in their resting center position without touching them.

STEP 3

Calibrate Outer Range

Slowly rotate both sticks in 3 full 360-degree circles along outer boundary edges.

CALIBRATION STATUS

Ready for Connection

Firmware-level calibration eliminates persistent stick drift without modifying in-game deadzones.

WebHID Calibration Guidelines

WebHID calibration requires Chrome or Edge on Windows or macOS over a direct USB-C connection.

How to Get Started

Just three steps to run a complete controller test and understand your controller's health status.

Connect Controller

Connect your controller to your computer via USB cable or Bluetooth. If the browser doesn't respond, press any button on the controller to activate the connection.

Button Detection

Press each button in the visual interface and confirm the corresponding area lights up on screen. This helps troubleshoot unresponsive or double-clicking buttons.

Sticks & Vibration

Rotate the sticks to check linearity and drift issues; click the vibration test button to feel if the left and right motor feedback is working properly.

What would you like to do next?

WebHID Firmware-Level PlayStation Controller Calibration

Traditional deadzone adjustments only mask stick drift in software. WebHID zero-point sampling reads raw 16-bit analog stick values directly from the DualSense hardware microcontroller.

Limitations & alternatives

This tool calibrates the base PlayStation 4 DualShock 4 and PlayStation 5 DualSense models over USB in Chromium browsers (Chrome, Edge). It does not support the DualSense Edge, PS VR2 Sense controllers, or restoring factory calibration.

For those models — and for quick + four-step calibration, expert mode, and restore/reboot — we recommend the free, open-source dualshock-tools (v2.27, actively maintained), which covers DualShock 4, DualSense, DualSense Edge, and PS VR2 Sense controllers and is widely recommended by the repair community on r/consolerepair.

Frequently Asked Questions

Everything you need to know about testing your controller.

How do I calibrate stick zero-point offsets on PS5 DualSense or PS4 controllers?

Connect your PlayStation controller to your computer via USB cable, click "Connect DualSense via WebHID", rest the sticks in center position, and click "Sample Center Offset".

What is WebHID hardware controller calibration?

WebHID is a modern browser API that communicates directly with Human Interface Devices (HID). It enables low-level memory sampling for DualSense and DualShock controllers without installing third-party software.

Does WebHID calibration fix PS5 stick drift permanently?

Yes! Re-centering software zero-point offsets recalibrates resting center values, resolving minor stick drift caused by spring wear without requiring soldering.

How this test works & its limits

This test reads your controller through the browser's standard Gamepad API — no drivers, no installs, nothing leaves your device.
Readings depend on connection mode: Bluetooth reports at lower rates than USB. Compare like-for-like (wired vs wired).
We measure the input reaching the browser — display lag and game-engine queues are outside this test's view.
A clean reading now does not guarantee no drift in-game: deadzones differ per game, and wear develops over time. Use the Drift Timeline to track yours.
This is a diagnostic, not a hardware-lab certification. For repair or RMA decisions, confirm with a second run or second tool.
