ToolBench brings together the small utilities people search for every day and makes them fast, clear and private. There is nothing to install and no account to create. Open a tool, enter your values or choose a file, and read the result. Almost everything is calculated inside your own browser, which means your documents, photos and text are not uploaded to a server. Each tool page explains how the result is produced, lists tips for getting a good outcome and answers the questions people ask most often.
We test tools against known answers, state the formulas and limits on every page, and avoid claims we cannot support. Calculators for money, health and similar topics provide estimates and are not professional advice. You can read more about our approach on the About page, see exactly how data is handled in the Privacy Policy, or tell us what to build next.
Yes. There are no paid tiers, watermarks or sign-ups. The site is supported by advertising.
No, except in the optional AI cutout mode of the Image Background Remover, which clearly tells you before it sends a single photo to a server. All other tools process files on your device.
Yes. The pages adapt to small screens, and most tools work in current versions of Chrome, Edge, Firefox and Safari. Very large PDFs or videos need more memory and may be slow on older phones.
For routine work, yes, but you should double-check important figures. Calculators use standard formulas and simplified assumptions, and cannot replace advice from a doctor, accountant or lawyer.
