Why Tooloh?
Tooloh was created to provide a refreshingly fast and simple alternative to bloated, ad-heavy tool sites.
We believe that web utilities should be small, performant, and easy to use.
Most tools do their actual file and calculation work inside your browser, so common tasks stay fast and do not require uploads.
Analytics help us understand what people use so we can keep Tooloh fast and focused.
