How Our Tools Work
A result is useful only if you know what produced it. OGadget includes calculators, browser input tests, image utilities and personal workspaces. They do not all perform the same kind of check.
Calculations use the values you enter
The PPI Calculator uses horizontal pixels, vertical pixels and the display diagonal. It does not discover the physical size of your monitor. A 1920 × 1080 panel at 24 inches works out to about 91.8 pixels per inch; the same resolution at 27 inches is about 81.6 PPI.
The Download Time Calculator combines a file-size assumption, download speed and a throughput allowance. It does not run a connection test. Installation, unpacking and later updates can take additional time. Likewise, a printing-cost estimate includes only the material, electricity and other costs you supply.
Changing a number on the page changes the scenario. It does not change a device setting, make a purchase or verify a product specification. Pay attention to units: Mbps is not MB/s, and a battery’s mAh rating is not an energy value in Wh without a voltage.
Browser tests observe what the browser receives
The Keyboard Tester listens for key events while its test area has focus. A shortcut handled by the operating system may never reach the page. A missing event alone does not prove a broken key.
Display tests put patterns or steady colors on screen for you to inspect. They do not scan the panel, repair a pixel or certify color accuracy. The Refresh Rate Test measures browser animation callback timing, which should not be confused with a calibrated hardware refresh-rate measurement.
Camera and microphone tools request access when you start them. The implemented engines use the browser’s media APIs for a local preview or signal reading; they do not record or upload those streams. Stop ends the session’s media access. Device selection, browser permission and operating-system settings can still affect the result.
Selected images are processed by the image tools
The current color picker and converter decode the selected image in the browser. The picker samples a rendered canvas; the converter creates a new browser-encoded output. Their engines do not send the selected image to a conversion or color-analysis API.
The original file remains important. Resizing, browser encoding, transparency and source quality can affect the output. A converted image is not a promise to preserve animation, metadata, profiles or the editability of a source document.
Saving, exporting and importing are different actions
Some GTA 6 workspaces save records in browser local storage. Others, such as a simple calculator, only hold the current inputs in the page. A save in one browser is not an account or cloud backup, and the tools do not read Rockstar accounts or game saves.
A JSON export is a file you choose to keep. It can contain notes, progress, coordinates or a processed personal map image, depending on the workspace. Import controls check the supported structure before merging or replacing records; read the confirmation because the scope differs by tool. Keep a current export before restoring another version.
Private browsing, disabled storage, storage limits and clearing site data can prevent saving or remove an existing record. Moving from a preview address to OGadget.com also changes the storage origin; data does not move automatically.
Local processing is not an anonymous website visit
The current tool engines we reviewed do not rely on paid calculation or file-processing APIs. Some pages show a bundled, dated factual snapshot and links to external sources. Opening a source link is a separate visit to another website.
Serving the page still involves the website’s hosting, WordPress and delivery services. Google Analytics is enabled through Site Kit, and a Cloudflare browser measurement script is present. Those services are distinct from the calculation or file-processing engine. Their role is described in the Privacy Policy.
Browser support is another boundary. Fullscreen access, media permissions, file formats, input events and local storage vary. If a result looks wrong, report the page, inputs and conditions through Corrections & Feedback rather than treating a browser limitation as a hardware diagnosis.
