Want to reduce this signal? Here's how to reduce your browser fingerprint →

WebGL values can reveal GPU and browser rendering details. This is one local signal only; it does not prove you are uniquely identifiable.

Direct answer

WebGL Fingerprint Test: answer first

Inspect local WebGL fingerprint signals such as renderer, vendor, and capabilities. Use the result as an observable public-signal check with stated limitations, not as an absolute guarantee.

Last updated

What the WebGL Fingerprint Test checks

The test creates a local WebGL context and reads browser-exposed graphics values such as vendor, renderer, versions, limits, and extensions.

Some browsers restrict detailed renderer data. When that happens, the page labels the value as browser-limited.

Limitations

  • No comparison dataset is used, so rarity is not measured.
  • Private browsing modes, browser settings, and GPU drivers can change the result.
  • Extension lists can be long, so the page shortens long display values.
  • The result stays in this browser page unless you copy it.

Reduce exposure

What to do next

WebGL exposure is controlled by browser privacy settings and graphics feature availability.

  1. Use browser fingerprinting protections where available.
  2. Review whether disabling or limiting WebGL is acceptable for your browsing needs.
  3. Keep graphics drivers and browser versions current.

Supporting evidence

Use this WebGL and GPU capability signals as one browser signal, not a full verdict

Run this subtest before and after one browser/privacy setting change when you need focused evidence. For a combined IP, DNS, WebRTC, IPv6, fingerprint, and User-Agent view, use the Public Exposure Report.

BaselineRun the subtest before changing browser, extension, GPU, font, or privacy settings.
RetestChange one setting, restart the browser if needed, and rerun the same subtest.

About this checkWhat it checks, what it cannot, and how to read it

Check my browser/privacy

What this checks

Visible browser/session signals such as public route, DNS/WebRTC/IPv6 behavior, fingerprint traits, user-agent, or public IP context.

Limits

What this cannot check

It cannot certify anonymity, inspect every app, or prove that a VPN, ISP, device, or account is safe.

Read results

How to use the output

Treat results as review signals for this browser/session or public target. Re-test after one change, then use Safe Copy or notes that avoid raw identifiers.

Quick reference

WebGL Fingerprint Test: what this tool does

Checks local WebGL renderer, vendor, extension, and capability signals.

How to use

  1. Run the test and read the vendor and renderer rows first.
  2. Note whether the page reports unmasked renderer info or a browser-limited value.
  3. Re-run after changing a WebGL or hardware-acceleration setting.

What the result means

The page opens a WebGL context and reads vendor, renderer, version, shading language, maximum texture size, precision hint and the supported extension list, then hashes them. An unmasked vendor and renderer name the GPU fairly precisely; a browser-limited value means the browser withheld that detail.

Known limitations

  • Where WebGL is disabled or blocked the test reports it as unavailable. That is a browser state, not a score.
  • The extension list is shown truncated on the page while the hash covers the full list, so the two are not read the same way.
  • GPU driver and browser updates change these values on their own, without anything changing about your privacy setup.

WebGL Fingerprint Test — Common Questions

What information does WebGL expose about my hardware?

The WebGL API exposes your GPU renderer string (e.g. "ANGLE (NVIDIA GeForce RTX 4070 Direct3D11)"), vendor, supported extensions list, and maximum capability values. The renderer string alone often uniquely identifies a GPU model and driver version — making WebGL one of the most identifying signals in a browser fingerprint.

How should I use WebGL Fingerprint Test results?

Use the result to decide what to review next, make one change at a time, and retest in the same browser, network, domain, or provider context when possible.

What does WebGL Fingerprint Test not prove?

It does not prove anonymity, full security, complete deliverability, full reputation cleanliness, search ranking, or AI citation. It only reports the visible signals available to this tool.
