Web tools
A collection of privacy-friendly utilities that run in your browser.
Every tool runs locally; nothing is stored on the server.
Password generator
Choose strength and character sets and generate up to six secure, easy-to-use passwords at once.
BASIC auth passwords (for .htpasswd)
Build Apache-compatible lines from a username and password in your browser, then collect and save them as .htpasswd.
SSH public and private keys
Generate RSA or Ed25519 key pairs entirely in your browser. Copy the public key straight into authorized_keys and similar.
JSON converter & formatter
Format or minify JSON, export as PHP-style array(…) text, convert literals or CSV to JSON, with validation and tree preview — all in the browser.
Markdown editor and cheatsheet
You can check common Markdown syntax and preview the rendered result in your browser. You can also upload a .md
IP & DNS record lookup
You can check the IP address and DNS records from the URL or domain name. The browser queries Google Public DNS (DoH JSON API).
URL encode & decode
Percent-encode or decode URL and query strings in your browser. Switch between URL and full (component) modes with automatic detection.
