QRCGen — QR Code Generator — 301.st

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.
