Lightweight calculators such as biorhythm, sleep rhythm compatibility, age/time calculators and other helpful daily tools.
Formatters, encoders/decoders (Base64, URL encode/decode), HTTP header readers, and other utilities that speed up development tasks.
Our mission
We build simple, fast, and privacy-conscious tools that solve everyday problems. Our goal is to minimize friction: no complicated signups, clear interfaces, and results you can download or copy instantly. We believe useful web tools should be accessible to everyone — developers, designers, students, and casual users alike.
Principles & privacy
- Speed: Lightweight pages and efficient processing for fast results.
- Usability: Clean interfaces and sensible defaults so tools work for beginners and experts.
- Privacy: We do not store files or personal data longer than necessary. For sensitive content, we recommend using local tools or private workflows.
- Transparency: Clear explanations, sample commands, and guidance so you understand what each tool does.
How to use the site
Navigate the top menu or home page to find the tool you need. Most tools accept drag-and-drop uploads, offer common presets, and provide downloadable results. For developers, we offer command-line examples and suggested workflows to integrate conversions and optimizations into build pipelines.
Who is lfacys.com for?
Our audience includes web developers, content creators, small business owners, students, and anyone who needs quick, reliable web utilities — from compressing dozens of images before publication to checking a domain’s WHOIS record or generating a strong password.
