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 and advertising help fund Tooloh and keep the site free to use.
