About OmniToolbox
OmniToolbox is a collection of fast, free, privacy-respecting online utilities. No clutter, no sign-ups, no dark patterns — just tools that do one thing well and load instantly.
Tools
Every tool is designed to be the clean, fast alternative to bloated or ad-heavy versions elsewhere. Current tools cover network diagnostics, security, developer utilities, and text processing:
- My IP & Privacy Audit — public IP, location, DNS leak, WebRTC leak, browser fingerprint, TLS version, and a full privacy exposure score
- VPN & Proxy Checker — detect whether your connection looks like a VPN, datacenter, or residential ISP
- WHOIS Lookup — domain registration info, age, expiry, and registrar details
- SSL Certificate Checker — inspect TLS certificate validity, issuer, and expiry for any domain
- HTTP Header Inspector — view all response headers returned by any URL
- Website Down Checker — test whether a site is reachable or down for everyone
- Password Generator — strong, customisable passwords generated entirely in your browser
- File Hash Verifier — compute and verify MD5, SHA-256, and SHA-512 checksums locally
- JWT Decoder — decode and inspect JSON Web Token headers and payloads
- JSON Formatter & Validator — pretty-print, validate, and minify JSON
- Regex Tester — live regular expression tester with match highlighting
- Cron Expression Builder — build and explain cron schedules in plain English
- Base64 Encoder / Decoder — encode or decode Base64 strings and files
- URL Encoder / Decoder — percent-encode or decode URL components
- UUID Generator — generate UUIDs in v1, v4, and v5 formats

Our approach to privacy
Wherever possible, tools run entirely in your browser — your data never leaves your device. When a tool needs server-side information (such as reading your public IP or fetching response headers), it reads only what is necessary to show you the result and stores nothing.
How the site is funded
OmniToolbox is free to use. It is supported by unobtrusive advertising via Google AdSense and occasional affiliate links. This keeps the tools free without paywalls or feature limits.
