How to Check Browser Fingerprint Using BrowserLeaks, Pixelscan, and CreepJS
When managing multiple online accounts from a single device, checking the browser fingerprint is a technical step that cannot be overlooked. Modern platforms rely not only on IP addresses but also on hardware and software parameters to create a unique identifier.
If these parameters conflict or duplicate, your accounts may face verification issues. This article guides you through the nature of browser fingerprints and how to use tools like BrowserLeaks, Pixelscan, and CreepJS.
By combining these testing tools with specialized software like PUR Browser, you can actively control hardware parameters and ensure a stable online workflow.

The Nature of Browser Fingerprints and Why Testing Is Necessary
A browser fingerprint is a collection of information shared by your browser when visiting websites. Unlike cookies which can be easily deleted, fingerprints are synthesized from screen resolution, installed fonts, graphics cards, browser versions, and time zones.
Each connected device creates a nearly unique parameter set. When businesses operate multiple accounts for marketing or customer care on the same computer, duplicate fingerprints cause systems to flag them as a single entity.
Regular fingerprint testing helps you detect configuration weaknesses early, allowing timely adjustments to protect your work sessions and avoid disruptions.
- Screen resolution and hardware configuration
- Graphics info via Canvas and WebGL
- Font lists and AudioContext
- Language and system time zone settings
Important Note
Testing browser fingerprints helps you understand what information your device is leaking externally.
Evaluating Hardware Parameters with BrowserLeaks

BrowserLeaks is one of the most popular websites used by engineers to check detailed information leaked by a browser. It divides data into sections like IP, DNS, WebRTC, Geolocation, Canvas, WebGL, and TLS.
When accessing BrowserLeaks through an account management browser, you must closely observe WebRTC and DNS to ensure your real IP does not leak. If using a proxy, info displayed here must match the proxy's location.
Additionally, Canvas and WebGL show graphic rendering data. Reliable antidetect software injects consistent noise into these parameters to create distinct profile values without breaking visual rendering.
- Check for WebRTC and DNS leaks
- Evaluate GPS coordinates and time zone consistency
- Review Canvas and WebGL rendering parameters
Testing Tip
Always check the WebRTC section first as it is the most common cause of real IP leaks when using proxies.
Checking Overall Reliability with Pixelscan
Pixelscan helps you evaluate whether your browser configuration resembles a real user. Unlike basic parameter checkers, Pixelscan analyzes logical relationships between various factors.
For example, if your browser language is Vietnamese but your time zone and IP belong to a European country, Pixelscan flags this inconsistency. Contradictory parameters attract attention from moderation systems.
Using Pixelscan helps you verify whether profile configurations are fully synchronized before starting work, which is useful for agencies and marketing teams.
- Evaluate IP and geographical location sync
- Check HTTP Headers consistency
- Detect abnormal configuration signs
Operational Suggestion
Ensure all parameters from language and time zone to proxy are synchronized to a single region before testing on Pixelscan.
Advanced Uniqueness Analysis with CreepJS
CreepJS is considered one of the most advanced and rigorous browser fingerprint testing tools. It runs hundreds of hidden tests to evaluate spoofing levels and device uniqueness.
Results from CreepJS include trust scores, warnings about modified APIs, and browser prevalence on the internet. If a configuration is too perfect or missing core APIs, CreepJS flags anomalies.
For professionals, CreepJS results help understand how anti-detection technologies interact with hardware layers, guiding appropriate noise injection levels.
- Score overall device trust
- Detect anomalies in core APIs
- Test browser responses to hidden scripts
Managing and Optimizing Fingerprints with PUR Browser
Manual testing via the tools above becomes highly effective when combined with a professional profile manager like PUR Browser. It is designed to help businesses operate multiple independent accounts securely.
PUR Browser allows creating unlimited browser profiles with separate cookies, caches, and login sessions. Its core strength lies in hardware fingerprint tampering, injecting consistent noise into Canvas, WebGL, AudioContext, and fonts.
Furthermore, assigning HTTP/SOCKS5 proxies with auto-matched time zones, GPS, and languages resolves parameter conflicts. Data is stored locally on the user's machine, ensuring privacy and teamwork efficiency via RBAC.
- Manage unlimited independent profiles
- Consistent hardware fingerprint noise injection
- Auto-match time zone, GPS, and language with proxy
- Secure local data storage and team permissions
Practical Experience
You can download the free version of PUR Browser at purbrowser.com to test configurations on tools like BrowserLeaks yourself.
Step-by-Step Profile Testing and Configuration Workflow
To ensure all profiles operate stably and pass technical checks, you should apply a standardized workflow before putting accounts into active use.
The first step is creating a new profile on the management software, then assigning an appropriate HTTP or SOCKS5 proxy. Always check proxy speed and latency before opening the browser.
The next step is opening the profile and visiting testing sites like BrowserLeaks, Pixelscan, and CreepJS sequentially to validate all parameters from IP and WebRTC to Canvas and time zones.
- Step 1: Create a new profile and assign a precise proxy
- Step 2: Check proxy latency and country
- Step 3: Open profile and visit BrowserLeaks, Pixelscan
- Step 4: Validate time zone and GPS synchronization
Operational Warning
Do not use profiles immediately after creation; always spend a few minutes thoroughly checking technical parameters.
