About Utilifyer
Free, fast, and private online tools for everyday tasks. No sign-up, no installs, no data collection.
Our Mission
We built Utilifyer because we were tired of opening five different tabs to do simple tasks — converting units, calculating percentages, generating passwords, or checking color contrast. Every tool we needed was buried behind sign-up walls, ad-heavy interfaces, or paywalls.
Utilifyer puts everything in one clean, fast place. Every tool is free, works instantly, and runs entirely in your browser — your data never leaves your device.
Fast
Tools load instantly. No accounts, no loading spinners, no waiting.
Private
All processing happens in your browser. We never see your data.
Free
Every tool is free forever. We keep the lights on with non-intrusive ads.
What We Offer
Utilifyer is home to a growing collection of tools across many categories:
Built to be Trustworthy
All tools are built using standard web technologies and run 100% in your browser using the Web Crypto API, Canvas API, and other native browser capabilities. Sensitive operations like password generation use crypto.getRandomValues() — the same cryptographically secure source your browser uses for HTTPS. We do not use any server-side processing for tool computations.
