Ordiveo

Ordiveo is a set of browser tools built on a single constraint: nothing you open is ever uploaded. Compressing a PDF, converting a photo, generating a QR code — the work happens inside the browser tab, on your own machine, and the file never reaches a server.

That constraint is the point rather than a feature. The documents people put through tools like these are contracts, payslips, bank statements and passports, and the ordinary way of doing it means handing all of that to somebody whose access logs you cannot see. The site has a page explaining how to check the claim rather than asking anyone to take it on trust — open the network tab, or disconnect from the internet and keep working.

Alongside the tools sit reference tables for engineering work, computed at build time from the standards themselves rather than transcribed from another site. That turned out to matter: the rebar weight chart shows that the familiar d²/162 shortcut runs about 1.2 kg high per tonne, and that two of the eleven bar masses circulated everywhere disagree with the geometry in opposite directions, so they cannot both be right. The cable size table shows 12 AWG sitting 17% under 4 mm² — and, at the other end of the range, 1 AWG sitting 21% over, so no rule of thumb survives the whole table.

Every calculator names the standard it follows and offers both conventions rather than quietly assuming the American one, which is the difference between a number you can put in a bill of quantities and a number you have to check. The whole site is published in English and Arabic.
