Convert between world currencies at daily rates.

This one isn’t a wiring job — the calculator engine needs live exchange rates. A static table would silently misprice money the day after it shipped, and fetching daily rates means calling a third-party API — which this product’s "nothing leaves your device" promise treats as a product decision, not a wiring gap. Saying so beats a dropzone that quietly does nothing.
The rest are live — try convert lengths, convert temperatures or work out a loan.

Questions about currency converter
Yes — no watermark, no daily cap, no signup. Pro raises the file-size and batch limits, but the tool itself is not gated.
No. This tool runs entirely in your browser. Open your network inspector and watch while it works — there are no file uploads, because there is no upload endpoint.
Up to 10 files at 15 MB each. Everything runs in your browser, so the real ceiling is your device’s memory — the cap keeps a large file from exhausting the tab.
