Can I hide my GPU info?

Limited. Firefox resistFingerprinting returns spoofed values. Brave randomizes some parameters.

Why do integrated/discrete GPUs differ?

Different rendering pipelines and drivers. Laptops show the active GPU's fingerprint.

Do driver updates change the fingerprint?

Yes. Updated renderer strings produce new hash values.

Is this the same as canvas fingerprinting?

No. Canvas captures rendering output. WebGL queries GPU parameters directly. They are complementary vectors.

WebGL Fingerprint

Free online WebGL fingerprint checker. View your WebGPU/WebGL fingerprint hash and see what GPU model, driver version, and graphics capabilities trackers can extract from your browser.

Free online WebGL fingerprint checker. View your WebGPU/WebGL fingerprint hash and see what GPU model, driver version, and graphics capabilities trackers can extract from your browser. Open the tool -- your WebGL fingerprint is analyzed automatically. Review the SHA-256 hash of your GPU vendor, renderer, and capabilities. Check the specific values exposed: GPU model, driver, max texture size, shading language version. Use the fingerprint hash to compare across browsers and privacy configurations. Uses the WebGL API to query GPU vendor, renderer, shading language version, and texture limits. These values are combined and hashed to create a fingerprint that can identify your device across websites. 100% client-side.
