Asset and equipment labels
Serial numbers, service dates and part codes readable by any phone, with no asset system to log into.
No link, no format, no app: whatever you type is what the scanner reads. The right choice when the code has to carry words rather than send someone somewhere.
No manual required — but here's the whole flow, start to finish.
Type or paste the text you want the code to carry
Watch the preview — the more you type, the denser it gets and the harder it is to scan
For anything long, raise the printed size rather than shrinking the code
Download the SVG for print, and scan it to confirm the text reads back exactly
Pump 4 — serviced 12 Mar 2026. Next service due Sep 2026. Filter type B. Nothing at all is added: no scheme, no prefix, no wrapper. The scanner shows the text exactly as typed.
Serial numbers, service dates and part codes readable by any phone, with no asset system to log into.
Longer label text than a plaque can hold, without needing a signal in the building.
Inside a panel or on a meter, where nobody could read printed small text.
Anything a person needs to read on the spot rather than be taken to a website for.
In theory a few thousand characters. In practice, keep it under a couple of hundred: past that the squares get so small that ordinary phone cameras in ordinary light start failing. If it does not fit, put the text on a page and encode the link instead.
Only if you control who can see the code. A QR code is not encryption — anyone who photographs it reads the text. Treat it as writing on the label, just in a font people cannot read.
Yes — the text is encoded as UTF-8, so Hindi, Arabic, Chinese, Cyrillic, emoji and accents all survive. Non-Latin characters take more space, so the code will be denser for the same number of characters.
No. The code is drawn in your browser with JavaScript — nothing you type is sent to AroraLabs or to any other server, and nothing is stored. You can prove it: load the tool, go offline, and it still works.
PDF utilities, image editors, calculators, dev tools and more — same rules: no login, nothing uploaded, no watermarks.
