Small conversions come up constantly in day-to-day engineering: reading a hex dump, checking whether a permission mask is right in binary, working out how many GiB a quota really is, or turning a PNG screenshot into a lighter WebP for a README. These converters handle those jobs instantly, without a server round-trip.
Every converter on this page runs entirely in your browser. Numbers are converted with JavaScript BigInt, so very large values keep full precision. Images are re-encoded with the Canvas API on your own device — the file is never uploaded anywhere.
