NullTools
Free online tools that run entirely in your browser
31 free tools — JSON, Base64, hashing, JWT, QR codes, images, colour and text. Everything runs client-side, so nothing you paste or upload ever leaves your device.
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.
