Tip, discount, unit conversion and more
Cake Toolbox is K-K’s free web utilities collection at k-k.page. Where possible, tools run in your browser to reduce unnecessary data transfer; pages that call AI or external APIs explain what is sent. Calculator and converter outputs are for reference only—not legal, tax, financial, or medical advice.
If something looks wrong, email us with the page URL. Many sites offer similar widgets; we aim to add clear context, limitations, and safe-use notes—not just the bare UI.
It varies by tool—read the notice on this page. Many converters and generators run fully client-side.
You may use it for personal or work reference. Uses that harm site operation (e.g. resale, abusive automation) may be restricted under our Terms.
