QR Code Generator & Scanner

Generate and scan QR codes. Custom colors, logo embed, vCard / Wi-Fi / event templates, bulk CSV export, and history.

Generate QR codes and scan QR codes inside your browser, no signup, no expiration, no watermark, no scan limit. The free QR code generator handles URL, plain text, vCard, Wi-Fi, calendar event, payment, and geo. The QR code scanner decodes QR codes from any image on the page or an uploaded file. Your data never leaves the browser. 🚀 🚀 WHY THIS QR CODE GENERATOR & SCANNER Most online QR code generators pull a bait-and-switch. The QR code looks free until you print 500 flyers, then a "subscribe to continue" page hijacks every scan. Or the QR code expires after 14 days. Or the QR code carries a watermark that only shows up on the printed copy. Or the QR code generator demands an email for what your browser can do locally. This Chrome extension is the opposite. The QR code generator runs 100% inside the popup, the scanner runs 100% inside the popup, and a static QR code you generate today still scans in 2030. Pro adds dynamic QR codes with real scan tracking for users who actually want analytics, but every QR code is yours forever once you click Download. It is fast. It is offline-first. It is privacy-respecting. It stays out of your way until you click the icon. ⚡ EVERYTHING IN THE FREE PLAN ✓ Generate from any URL with live preview ✓ Generate from plain text ✓ Wi-Fi template (SSID, password, security type) so guests join in one tap ✓ PNG download at the default size with crisp anti-aliased modules ✓ Scan a QR code from any image on the active tab via right-click ✓ Scan every QR code on the current page in one click from the Scan tab ✓ Auto-detect decoded type (URL, vCard, Wi-Fi, calendar, geo, plain text) ✓ Recent history of the last 5 ✓ Black-and-white default colors with medium error correction ✓ Thirty generations per day, no signup, no email, no credit card 🔓 WHAT PRO UNLOCKS ✦ SVG download for print-quality QR codes that scale perfectly to billboards or business cards. ✦ Full color picker for foreground and background, including transparent backgrounds for layering on flyers and decks. ✦ Embedded center logo with a built-in safe zone so your brand mark sits inside the code without breaking scannability.

Event organizers printing wristbands and signage with one QR code per attendee. Restaurant owners generating a QR code menu they can update each season without reprinting. Property managers generating Wi-Fi QR for guest networks. Real estate agents adding a scan-to-call QR to listings. Conference speakers sharing slide decks via vCard QR. Anyone who has ever typed a 28-character Wi-Fi password into someone else's phone instead of generating a Wi-Fi QR in five seconds. 🛠️ HOW IT WORKS 1. Pin the QR code generator extension to your toolbar after install. 2. Click the icon to open the popup. Generate is the default tab. 3. Pick a template (URL, text, vCard, Wi-Fi, calendar, payment, geo) and fill the form. 4. Watch the preview update live as you type. 5. Click Download for PNG, or scan straight back from PNG; pick Download SVG (Pro) for print quality. 6. To scan a QR code, switch to the Scan tab or right-click any image on the active tab and choose Scan QR in this image. 💡 REAL USE CASES → Print a vCard QR on the back of a business card so anyone who scans it gets your contact details into their phone in two seconds → Stick a Wi-Fi QR on the fridge so houseguests join the network without ever asking for the password → Generate one per ticket holder for a conference in bulk, each encoding a unique check-in URL → Add a SEPA payment QR to a paper invoice so European customers settle with one bank app scan → Drop a geo QR on a real estate flyer so prospective buyers get walking directions to the property → Use a dynamic QR on a printed restaurant table tent so you can swap the menu URL each season without reprinting → Generate one QR per product SKU and stick them on warehouse bins for instant inventory lookup → Decode a suspicious QR sticker on a parking meter without having to point your phone at it → Scan a code from a webinar slide on screen without reaching for a phone 🔒 PRIVACY YOU CAN VERIFY Your content never leaves your browser. All generation, all decoding, all template encoding, and all rendering run 100% locally inside the popup. The only network traffic the extension makes is a license check (a random device ID, no personal data) and an anonymous funnel counter. The dynamic QR feature, which is opt-in and Pro-only, is the only piece that talks to our redirect server, and even then only the destination URL you type and an anonymous scan counter are stored. We never see your content. We never sell your data. We never email you unless you opt in. 📊 PERFORMANCE & BENCHMARKS Generating a typical 25-version code takes under 10 ms on a typical laptop. The scanner decodes a 1024x1024 image in under 60 ms. The bulk QR code generator processes 500 rows in under 6 seconds, including ZIP packaging. The whole bundle ships at roughly 110 KB gzipped (jsQR scanner is the heaviest piece), so Chrome stays light. Every code is rendered in vector form internally, then rasterized to PNG or exported as SVG for print. 🆚 WHY THIS OVER THE ALTERNATIVES ✓ Unlike paid online generators, your data never gets uploaded to a remote server. The QR code is generated in the browser. Your URL stays private. ✓ Unlike subscription services, codes never expire, never redirect to a paywall, and no scan ever fails because of a hidden cap. The QR code generator runs locally, the scanner runs locally, and you never depend on a server. ✓ Unlike tools that demand an email, this extension requires zero signup. Install, click, generate. ✓ Unlike most mobile apps, no ads, no tracking, no upsell modal every third code. ✓ Unlike Chrome's built-in "share this page as QR code", you can encode any text, vCard, Wi-Fi, payment, geo, or bulk batch, not just the current tab URL. ✓ Unlike free generators that only do PNG, Pro outputs vector SVG ready for print at any size. 🛡️ SECURITY Manifest v3. Zero remote code. No external CDN dependencies. The QR code generator (qrcode-generator) and scanner (jsQR) ship inside the bundle. Every release is audited by the lint-remote-code tool before submission. activeTab plus scripting (no host_permissions for the open web) means the extension only runs when you click the icon or right-click an image, never silently in the background. ❓ FREQUENTLY ASKED QUESTIONS Q: Does it work offline? A: Yes. Every free feature works without a network connection. Pro license verification needs network the first time, then caches for 24 hours. The dynamic QR code feature is the only piece that requires connectivity at scan time, because it talks to our redirect server. Q: Will my codes expire? A: No. Static QR codes never expire. The bytes are baked into the image at generation time. The QR code you download today will scan in 10 years. Dynamic QR codes (Pro) keep working as long as your Pro plan is active, plus a 90-day grace window after cancellation. Q: Do I have to sign up? A: No signup, no email, no credit card. Install the extension and start generating codes. The thirty-per-day cap on the free QR code generator is anonymous and resets each midnight. Q: How do I make a Wi-Fi QR code? A: Pick the Wi-Fi template, type your network name (SSID), password, and security type, hit Download. The Wi-Fi QR code joins any phone to your network with one scan, no typing. Q: How do I add a logo? A: Switch to Pro, upload a PNG of your logo in the Design panel, and the generator embeds it in the center with a safe zone and high error correction so the code still scans cleanly. Q: How big a code can the QR code generator produce? A: Up to QR version 40 (177x177 modules), which holds about 4,296 alphanumeric or 2,953 binary characters. That covers vCards, multi-line addresses, small JSON payloads, and Wi-Fi credentials with very long passwords. Q: Can I scan from a screenshot? A: Yes. Open the popup, switch to the Scan tab, and use Upload image to scan. The QR code scanner runs locally on your device. Q: What is the difference between Monthly ($2.99) and Lifetime ($9.99)? A: Same Pro features, different commitment. Lifetime pays for itself in just over four months of Monthly and never charges again. Both are one Stripe checkout, no auto-trial. Q: Can I get a refund? A: Within 30 days of purchase, full refund on request. Email support@peakproductivity.online and we will refund. No questions, no cancellation maze. 🚀 GET STARTED Install the extension, pin it to your toolbar, type a URL into the Generate tab, and download your first QR code in under 60 seconds. From there, try the Wi-Fi QR code template, scan a QR code with the right-click menu, and you will already have used most of what people pay $40 a month for elsewhere. The QR tool every marketer, event organizer, restaurant owner, and small business eventually wishes they had installed sooner.
