What is this tool?
This device info tool shows the details of the phone, tablet, or computer you open it on, starting with one plain-English sentence such as which browser and Windows, macOS or Android version you are using. Where the browser allows it, it reads client hints for the exact OS version, CPU architecture and Android model. Below that are Browser & system, Screen & viewport (sizes, pixel ratio, colour gamut, HDR), Device (type, model, CPU threads, memory, GPU, battery, storage for this site), Preferences & privacy (dark mode, reduced motion, contrast, Do Not Track, Global Privacy Control), Media playback (H.264, HEVC, VP9, AV1, AAC, Opus, FLAC) and about 30 Supported features such as WebGL, WebGPU and WebAssembly. Copy link for tech support creates a shareable report link, and Copy full report or Download .txt gives a text version. Everything is read from browser APIs locally.
How to Use
- Open the page on the device you want to check. Details load automatically.
- Read the plain-English summary at the top, for example which browser and operating system version you are using.
- Scroll through Browser & system, Screen & viewport, Device, Preferences & privacy, Media playback and Supported features for the full list.
- Resize the window or rotate your phone. The sizes update, or click Refresh.
- Click Copy link for tech support to share the report as a link, or Copy full report / Download .txt for a text version.
Frequently Asked Questions
What is the difference between screen size and viewport size?
Screen size is the full display measured in CSS pixels. The viewport is the part of the browser window that shows the page, and it shrinks when toolbars and tabs take up space.
Why doesn't it show my exact iPhone or iPad model?
Safari does not share the exact model with websites, so the tool can only report iPhone or iPad. On Android the model is read from the user agent or browser hints when the browser provides it.
How do I send my device details to tech support?
Click Copy link for tech support and paste the link into your email or chat. The details are packed into the part of the link after #, which browsers never send to a server, so nothing is stored by Wivrix. Whoever opens the link sees your report, clearly marked as shared.
Why does it say Windows 10 or 11, or no macOS version?
Browsers freeze parts of the user agent. Chrome and Edge share the exact Windows and macOS version through client hints, which this tool reads. Firefox and Safari do not, so the tool tells you when the version cannot be known.
Why is the screen resolution lower than my phone's specs?
Browsers report sizes in CSS pixels, not physical pixels. Multiply by the device pixel ratio to get the physical resolution. For example, 390 x 844 at 3x is 1170 x 2532.
