Free Online URL Parser & Query String Manager

Overview

A clean, professional, and efficient browser-based tool designed to parse, analyze, and manipulate URLs and query strings. It provides a visual interface to break down complex URIs and reconstruct them for testing, development, and debugging purposes.

Feature List

• Real-time URL Parsing: Instant breakdown of a URL into Protocol, Domain, Port, Path, Hash, and Search parameters.
• Dynamic Query Editor: Add, remove, or edit key-value pairs within the query string with an intuitive UI.
• URL Encoding/Decoding: One-click functionality to URL-encode or URL-decode specific parameters or the entire string.
• Reconstruction Preview: An automatically generated, up-to-date output URL that reflects all changes made in the editor.
• Clipboard Integration: Dedicated "Copy" buttons for the full URL and specific parameters.
• Zero-Storage Architecture: Designed to work entirely in-memory, ensuring compatibility with sandboxed iframe environments.

UI Layout

• Header: Simple and clean title with a brief explanation of the tool.
• Main Input Area: A large, responsive textarea for pasting the source URL with an auto-clear button.
• Component Breakdown: A card-based display showing non-editable components (e.g., protocol, origin, hostname).
• Parameter Management Table: A vertical list of rows for query parameters, each featuring an "Input" (Key) and "Input" (Value), along with a "Delete" button.
• Results Section: A read-only, highlighted box showing the final reconstructed URL with a "Copy to Clipboard" action.

Color Palette

• Primary Surface: White (#FFFFFF) with light gray (#F9FAFB) backgrounds for sections.
• Primary Action: Energetic blue (#2563EB) for primary buttons.
• Surface/Card: Neutral gray (#E5E7EB) borders with subtle shadows (shadow-sm).
• Text: Dark slate (#1F2937) for readability, lighter gray (#6B7280) for metadata.
• Interactions: Subtle hover states (darker blue for buttons) and soft transitions.

Implementation Directives

• Single File: All logic, structure, and styling must reside within a single HTML file.
• Vanilla Stack: Use plain JavaScript and HTML5. Tailwind CSS should be pulled via CDN for styling efficiency.
• Browser Storage: ABSOLUTELY NO localStorage, sessionStorage, or cookies. All application state must be stored in standard JS objects/variables.
• Responsive Design: Ensure input textareas and parameter tables stack gracefully on mobile devices (e.g., mobile = column, desktop = grid/flex).
• Performance: Minimize DOM re-renders by using light-weight update logic when parameters are added or removed.
