Copy Cleaner

Copy selected webpage text as clean plain text or lightweight Markdown.

Page Exporter is a Chrome Manifest V3 extension that runs entirely in your browser. There is no remote server, no sign-in, and no web app bundled alongside it. When you open the toolbar popup on a supported web tab, it shows the current page title, a synced preference (“Use selected text when available”), and four actions: Export Page as Markdown; Export Page as Text; Export Links as CSV; Export Images as CSV. A status line reports success or a readable failure message when the tab cannot export (for example protected chrome:// pages). Exports are orchestrated through the MV3 service worker (background.js) using message passing: - The popup (or context menu handler) asks the extension service worker to export from a specific tab. - The service worker sends a one-shot EXPORT message to the tab’s injected content script (content.js). - The content script returns extracted text/data. - The service worker triggers chrome.downloads.download using a UTF-8 data: URL constructed in the worker (blobs/Object URLs are avoided because extension service workers do not provide URL.createObjectURL). Markdown and plain-text exports include a short document header with the page title and URL when exporting the readable region or a selection. CSV exports use standard columns: - Links: text, url, domain - Images: alt, src, width, height Content selection uses a lightweight “readability” style heuristic implemented in content.js: prefer document article, then main, then body; strip script/style/nav/footer/header/aside and a few banner/navigation-related role attributes before conversion. Results depend on site structure; dense single-page apps may still surface UI chrome or need the user to select text manually. Right-click context menu entries (registered in background.js in the extension service worker) mirror key actions: - Export this page as Markdown (page, frame, or link context) - Export selected text as Markdown (selection context) - Export all links as CSV (page, frame, or link context) The “Use selected text when available” setting is stored in chrome.storage.sync under the key useSelectionWhenAvailable (default: on when first read). When enabled, Markdown and Text exports prefer the current text selection when it is non-empty; otherwise they fall back to the readable region. Privacy stance in plain terms: Page Exporter does not ship browsing history or page contents to the developer—we do not operate backend infrastructure for this product. Exported files are written only where the user’s browser downloads settings send them. FEATURE SUMMARY (EXPORT MODES AND UI) ------------------------------------- Popup actions: - Export Page as Markdown — readable region or selection (see toggle); includes title/URL header and Markdown body. - Export Page as Text — plain text from readable region or selection. - Export Links as CSV — links discovered within the same readable subtree used for extraction (columns: text, url, domain). - Export Images as CSV — images discovered within that subtree (columns: alt, src, width, height). Context menu actions: - Export this page as Markdown — full-page style export (does not consult the popup selection toggle path; always uses the content script’s page export mode for markdown). - Export selected text as Markdown — selection-only Markdown wrapped with the same title/URL header pattern. - Export all links as CSV — same links CSV extraction as the popup. Download filenames use a sanitized page title plus a date-time stamp (see background.js).
