About OGadget
OGadget is a collection of free tools for the small technical questions that come up when you own, use or make things with technology. Check which keyboard inputs reach your browser. Compare the dimensions of two displays. Estimate the cost of a print or the time a download might take. Keep a personal plan for your next game session.
The point is to give you something you can use, with enough explanation to understand the result.
A tool should do a specific job
A monitor’s diagonal does not tell you its width. A power bank’s capacity label does not tell you exactly how many times it will charge a phone. A browser can display a screen test, but it cannot examine the electronics behind the panel. Those distinctions shape the applications here.
Our PPI Calculator connects resolution to physical screen size. The Keyboard Tester shows input events received by the browser. The Image Converter prepares an output file from an image you select. They solve different problems, so their methods and limits are different too.
The collection spans smartphones and devices, hardware diagnostics, digital and creative utilities, maker calculations, and gaming. Some tools return a number. Others provide a visual check or a place to organize your own information. None of those results should be read as more than the application actually measures or calculates.
Rebuilt under new ownership
OGadget.com previously belonged to another owner. The current OGadget site is a new build centered on interactive technology tools. Earlier material associated with the domain should not be taken as a description of the current platform or its publisher.
The familiar connection to gadgets remains practical: screens, batteries, keyboards, images and the everyday decisions around them. The site is not presented as a testing laboratory, a manufacturer’s support service or a certification body.
Available applications and work in progress
An available tool has a working interface for the function described on its page. That does not mean every possible device, browser or data source is supported. The instructions explain the inputs required, and the method explains what a result means.
Applications under development are a separate category. A planned feature is not an available feature merely because it has a name or a proposed page. We do not want you entering information into what looks like a finished tool only to discover that its essential function is missing.
Gaming tools need another distinction. Some GTA 6 workspaces already support personal checklists, budget assumptions and locally saved plans. Others contain a limited sourced snapshot alongside personal entries. A working planning interface does not make an incomplete vehicle list exhaustive or an assumed download size official.
Check the method, then use the result
Most of the useful detail sits beside the application: units, formulas, examples, source dates and limitations. Start with How Our Tools Work if you want to understand browser processing and local saving. Our Editorial & Data Standards explain how factual claims and estimates are treated.
If something is wrong or difficult to use, send a correction or a reproducible bug report. A page is more useful when its limits are clear and its mistakes can be reported.
