What You Can Do Here
Shansu Tools provides practical web utilities for common day-to-day tasks: preparing ID photos, editing images, converting PDF files, estimating daily calories, calculating BMI, estimating mortgage payments, and computing date differences. Each tool is built to be fast and lightweight so you can use it immediately from desktop or mobile.
We focus on clear output and low friction: no signup wall, no long setup flow, and no unnecessary forms. For most workflows, your files stay local in the browser instead of being uploaded to a remote processing queue. This design helps reduce waiting time and also improves privacy.
Install as an app: Open any tool, then use your browser’s Install app or Add to Home Screen option (e.g. Chrome menu or Safari Share) to add it to your home screen or launcher for quicker access.
