meinove is a small collection of browser-based tools, calculators and games. It exists because the same handful of everyday tasks — shrinking an image, merging two PDFs, checking a JSON payload, working out what a loan really costs — are served mostly by sites that want an account, impose a daily limit, or upload your file to a server for no technical reason.
The one rule the site is built around
Your files stay on your device. Every tool here processes data using APIs built into your browser — the File API, Canvas, TextEncoder, and a PDF library that ships with the page and runs locally. There is no upload endpoint anywhere on this site. There is no database of user files, because there are no user files to store.
You do not have to take that on trust. Open any tool, wait for the page to finish loading, then switch off your internet connection and use it. It will work. A tool that uploads your file cannot do that.
There is exactly one exception, and it is stated on its own page: the currency converter fetches exchange rates from a public API, because an exchange rate is information that has to come from somewhere. It sends only a request for the rate table — never the amounts you type.
How the site is built
Static HTML, one stylesheet, and a small JavaScript file per tool. No framework, no tracking scripts, no cookie banner, because there are no cookies to consent to. Pages are a few kilobytes and load essentially instantly, including on a slow mobile connection.
This is not minimalism for its own sake. A tool you reach for once a week should open before you have finished thinking about what you wanted to do with it.
How it is funded
Advertising, through Google AdSense. Three ad slots per page, in fixed positions, with the space reserved in the layout so nothing jumps around while you are reading or working. No pop-ups, no interstitials, no ads overlapping the tool controls, and no auto-playing anything.
Stating this plainly matters more than it might seem. Ad-funded means our incentive is pages that people find useful enough to visit and return to — not pages engineered to keep you scrolling. If a tool here does its job in ten seconds and you leave, that is the tool working correctly.
Editorial approach
Every tool page explains what the tool does, how to get good results from it, and what it deliberately does not handle. The compound interest calculator says outright that it ignores inflation, fees, tax and volatility, and explains how much each of those matters. The image compressor explains why converting a photo to PNG makes it larger. The typing test notes that consecutive attempts vary by several words per minute, so small changes are noise rather than progress.
Overstating what a tool can do wastes more of your time than a tool that is simply slow. Where something is not viable in a browser — batch-converting camera RAW files, editing text inside an existing PDF, live tick-level exchange rates — the page says so and suggests what to use instead.
Accessibility and devices
Pages are built mobile-first and tested at 360 px width. Interactive controls meet the 44 px minimum touch target, every input has a real label, the games are keyboard-navigable, and light and dark themes both follow your system setting. If you hit something that does not work with a screen reader or keyboard, that is a bug worth telling us about.
