Hey Product Hunt 👋 I built NullTools because most "free online tools" quietly upload whatever you paste to a server. Every tool here runs entirely in your browser — no uploads, no accounts, no trackers. It is 31 tools now: JSON, Base64 and URL/HTML encoding, hashing, JWT, UUID/ULID, QR codes, image compression and conversion, colour tools, text diff, regex, Markdown, plus a few general ones like unit conversion and word counting. The test I like: open a tool, then disconnect from the network. It still works. Would love to know which tools you would actually use, and what is missing.
