About IyeTech
A growing collection of free, fast, and privacy-first browser-based tools. No account required. No files uploaded. No data collected.
Privacy by Design
Every single tool on IyeTech processes your data 100% client-side. Your images, text, passwords, and JSON never leave your device. We do not have access to what you process with our tools. There is no backend, no database, and no user tracking — just fast Web APIs running in your browser.
Our Principles
Zero Data Collection
None of your files, text, or inputs are ever sent to a server. Everything is processed locally in your browser using standard Web APIs.
Instant & Fast
Tools run directly on your device — no round trips to the cloud. Results are immediate, even offline.
Always Free
All tools are free to use, forever. The site is sustained by non-intrusive display advertising (Google AdSense).
Works Everywhere
Built as a fully static site deployed on Cloudflare Pages — globally distributed, fast, and highly available.

How IyeTech is Funded
IyeTech is funded through Google AdSense display advertising. Ads are shown in designated slots (top banner, bottom, in-content) and are clearly separated from tool content. We will never place ads that interfere with tool functionality or user privacy.
All tools remain completely free regardless of ad revenue. There is no premium tier, no paywalled features, and no account required.
