About EverydayTools
A small collection of tools that do one thing each, quickly and without asking for anything.
Why this site exists
Most online calculators are buried under pop-ups, demand an email address, or quietly upload your files to a server you know nothing about. EverydayTools is the opposite: 49 tools that load fast, work on a phone, and finish the job in the tab you opened them in.
How the tools work
Every calculator runs in your browser. So do the image and PDF tools, which use the browser's own canvas and PDF engines rather than sending anything away. There is no server that receives your photos, documents or numbers, because there is no upload step at all.
Each tool page shows the formula it used and a worked example, so you can check the result by hand rather than taking it on faith.
How it is funded
Advertising. Ad space is clearly labelled, kept visually separate from the tools, and never styled to look like a button or a download link. Nothing is gated behind an account or a paywall.
Accuracy and limits
The calculators use standard published formulas, but results are estimates for general guidance. They are not financial, medical, legal or academic advice, and they cannot account for your specific circumstances. For decisions that matter, check with a qualified professional or your institution.
