All the free tools
Every tool fastast serves, each on its own page. No account, no e-mail, nothing stored — open one, use it, close the tab.
Every tool here does one thing, on one page, and asks nothing of you: no account, no e-mail address, no cookie banner to dismiss before you can work. Type what you need, read the answer, close the tab. Nothing you enter is kept.
Each tool has its own address, so a link to one is a link to that tool alone. The list below is the whole set, and the search box filters it by name or by what a tool does.
