Features & Capabilities

QRCGen generates QR codes directly in the browser side panel — no popups, no new tabs, no interruptions.

FEATURES

  • Side panel UI — always accessible, doesn't block the page
  • Instant preview — QR codes generated locally, no network needed
  • Ultra-lightweight SVGs — ~5 KB each, single optimized path
  • Share links — permanent URLs at qr.qrcgen.com with global CDN caching
  • Embed snippets — HTML, Markdown, React, Vue formats ready to paste
  • History — recent QR codes stored locally for quick access
  • Dark and light theme — with auto-detection
  • 2 languages — English, Russian
HOW IT WORKS
  1. Click the extension icon — the side panel opens with a QR code for the current page
  2. QR code is generated locally — instant, works offline
  3. Copy the share link, download the SVG, or grab an embed snippet
  4. Share links resolve to edge-cached images that load instantly worldwide
PRIVACY

QRCGen runs entirely in your browser. QR codes are generated locally — no data is sent for the preview. The only network request is a cache-warming fetch so share links load fast for recipients. No accounts, no tracking, no analytics.

PERMISSIONS

  • Side Panel — to display the extension UI
  • Storage — to save your settings and history locally
  • Active Tab + Tabs — to read the URL of your current page

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
