How TrustyBench works

Every tool on this site does its work inside your browser. When you pick a file, it is read by your own device and never sent to a server. You can check this yourself: open your browser's developer tools, go to the Network tab, and run a tool. You will see no upload.

What we don't do

No ads. No tracking cookies. No accounts. No daily limits. No watermarks. We use a cookieless page counter so we know which tools people use, and nothing else.

Calculators

Every calculator shows the formula or table it used and where that came from. Trade calculators name the code edition they follow. They are references, not a substitute for a licensed professional or your local authority.

Works offline

Once a tool page has loaded, it keeps working without a connection. On a phone you can add it to your home screen.
