URL Shuttle

A small web app to parse, build, encode, validate, and edit URLs. Everything runs on the WHATWG URL API in the browser; no data is sent to any server.

Features

• Encoder / Decoder – percent-encode or decode with explicit buttons, encodeURIComponent / encodeURI modes
• Parser – break any URL into protocol, host, port, path, query parameters, and fragment
• Builder – assemble URLs from parts with automatic encoding
• Query editor – add, edit, sort, and bulk encode/decode query parameters
• Validator – batch-check URL lists, one per line, with specific issues reported
• Slug generator – turn titles into clean SEO-friendly slugs (stop-word removal, separators, case)
• Bilingual – English and Chinese UI
