Preview for Gmail & Chat: HTML, Markdown, JSON

Description

Preview HTML, Markdown, and JSON attachments from Gmail and Google Chat, and save any preview as a PDF. Tired of your inbox showing HTML attachments as raw source code? This extension renders HTML, Markdown, and JSON attachments the way they're meant to look — in a clean, full-screen viewer — without downloading them or leaving your inbox. • Web pages are rendered exactly as designed, in a secure sandbox. • Markdown documents are formatted with headings, tables, code blocks, and links. • JSON data opens as an interactive, collapsible tree with search, a raw-text toggle, and one-click copy. Common variants of these formats are supported too. • Print what you are reading, or save it as a PDF containing just the document — no mail-client furniture around it, and named after the file itself. How it works: Hover any supported attachment — in Google Chat, an open Gmail message, or your inbox list — and click the eye icon that appears. The file opens in a full-screen preview, ready to read, print or save. Press Esc or click Close to dismiss. Private and secure by design: • No accounts, no servers, no analytics, no tracking — nothing ever leaves your browser. • Files are rendered inside an isolated sandbox with no access to your Google account or session. • The extension only ever talks to Google's own file endpoints to fetch the file you chose to preview.
