oof.tools

Every tool runs in the browser. Your file is opened by the page you already have loaded, worked on there, and handed back — it is never sent anywhere, because there is no server-side step to send it to.

That one decision writes most of the rest of the product. There are no uploads to queue, no storage to pay for and no retention policy to argue about, so the tools can be free and can stay free. It also means the privacy claim on the front page is a description of the architecture rather than a promise about our conduct — a thing a visitor can verify by watching their own network tab.

The obvious tools are there — JSON, Base64, regex, diff, image compression and conversion, PDF merging, minifiers. So are the ones nobody else bothers with: VHF marine channels, Beaufort wind scale, port-to-port distances, boat running costs, catering staff counts, a Serbian net-salary calculator.

Those are the ones people actually search for and cannot find, and they are why the library is organised by what you are doing rather than by what kind of file you have.

Each tool is its own page with its own explanation, so it can answer a search on its own terms rather than depending on the home page. There is a blog of tutorials and format comparisons behind it, and a comparison page that sets out, plainly, what most other tool sites do with your file.

Every tool can also be shared as a link, shared with its result, or embedded in someone else's page.
