Free Online Tools
Without the Data Uploads

Most of what people need from the web is unglamorous. An image is four megabytes and the upload form will only take two. A JSON payload arrived on one line and is unreadable. A loan quote needs checking before it gets signed. None of that warrants installing software or creating an account, and yet the usual route is a site that wants your email address before it will resize a photograph.

ToolForge is 215 of those small jobs, each on its own page, each free, and each usable within a second or two of arriving. There is no dashboard to learn and nothing is held back for a paid tier — the tool you land on is the whole tool.

The design decision underneath all of it is that the work happens on your machine. When you compress an image here, your browser reads the file, re-encodes it on a canvas, and hands it straight back to you; the bytes never travel anywhere. That matters most for the files you would think twice about handing over — a passport scan, a signed contract, a screenshot with a customer’s details still visible in it. It also means there is no queue and no file-size ceiling set by someone else’s disk.

The exceptions are the thirteen tools that genuinely cannot work that way. A DNS lookup or a WHOIS query has to ask a server somewhere. Those tools say so on their own pages, and the methodology page lists all thirteen alongside the service each one contacts and precisely what gets sent.

The largest group here is the calculators, and they are held to a stricter standard than the rest: each one names the published formula it implements, shows how the result was reached, and says where it stops being useful. A BMI figure is arithmetic, not a diagnosis, and a repayment schedule ignores the fees a real lender will add. Naming the formula is what lets you check the number rather than trust it — which is the only reasonable basis for using a stranger’s calculator.
