Our Principles

🛡️

Local First

If the browser can do it, the server doesn't need to. Your files never leave your device.

01
🚪

No Login

99% of tools work without an account. We don't collect data or emails.

02
🎁

Free Forever

No paywalls. Ads, if any, are kept minimal and unobtrusive.

03

Fast

Everything pre-rendered and lazy-loaded. We don't chase feature counts; we chase load times.

04
About

About Shahefu

Shahefu is a collection of products maintained by hebeinanji (a backend engineer) in his spare time, launched since 2024. We believe the best part of the internet is the small things, done seriously — no popups, no tracking, no forced logins. All tools process data locally in the browser by default; all pages are pre-rendered for sub-second loads.
