About

**TextFlow** is a lightweight Chrome extension built for content creators, students, developers, and everyday browsers. No need to switch apps or open online tools — process, convert, and extract web content directly in your browser with one click.

**Core Features**

📊 **Word Count** — Supports both selection and full-page modes. Accurately counts Chinese characters, English words, total characters (with/without spaces), paragraphs, sentences, plus images, videos, and links on the page. An essential tool for writing, translation, and editing.

📝 **Markdown Export** — Convert web content to standard Markdown format with full support for headings, lists, links, images, tables, and code blocks. Features source/preview dual view with one-click copy or `.md` download for easy note archiving.

📋 **Plain Text Extractor** — Intelligently filters ads, navigation bars, sidebars, comment sections, and other distracting elements to extract clean body text. Optional merge blank lines and preserve link URLs for pure reading and citation.

🔲 **QR Code Generator** — Quickly generate high-definition QR codes from selected text or the current page URL. Copy to clipboard or download for easy sharing.

🔤 **Case Converter** — Switch between 9 naming styles: uppercase, lowercase, sentence case, title case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE. Perfect for developers and writers.

🔄 **Text Reverser** — Four reversal modes: reverse all, reverse words, reverse internal, and mirror reverse. Fun and practical.

📑 **Text Dedup / Sort** — Deduplicate and sort text lines with combined operations and optional blank line ignoring. Efficient data cleanup.

😄 **Emoji Converter** — Transform text into emoji keywords, regional indicators, circled letters, number emojis, and emoji art for more expressive communication.
