What is a qr code generator?

A QR code generator is the modern equivalent of a label maker — a small utility that takes a piece of structured data (a URL, a WiFi password, a phone number) and turns it into something a stranger's phone camera can pick up in half a second. The category has consolidated around a handful of hosted services (QRCodeMonkey, QRServer, the-qrcode-generator), all of which log every payload by default and gate the colour and shape customisation behind a paid tier. That's fine for one-off marketing flyers, but it's exactly the wrong shape for the use cases that actually matter: sharing a guest WiFi password, embedding a vCard on a printed business card, generating event badges in bulk, or wiring up a small thank-you-for-buying-this URL on a product label. For those, the right tool is local — generated once, used many times, with the operator in full control of the colour scheme and the embedded data lifecycle.

Common features

  • Four payload types — URL, plain text, WiFi (WPA/WEP/open + hidden), contact card (vCard 3.0)
  • Auto-https for bare hostnames typed into the URL form
  • Live canvas preview that re-renders on every keystroke
  • Size slider (160 → 600 px) with image-rendering: pixelated for crisp high-DPI display
  • Error-correction toggles (L 7% / M 15% / Q 25% / H 30%) with descriptive hints
  • Download as PNG (rendered at print-friendly resolution) or SVG (lossless)
  • Correct MeCard-style escape for WIFI: payloads — `\;`, `\,`, `\:`, `\\`
  • vCard 3.0 with empty fields skipped to keep the printed symbol small
  • Inline alert if the payload exceeds the current EC level's capacity
  • 100% client-side — no server round-trip on any encode

Real-world examples

Guest WiFi sticker for the office

Operator enters the SSID, password, and encryption type, downloads the SVG, prints it on a vinyl sticker, and sticks it next to the door. New hires scan once on their first day and they're online — no help-desk ticket, no whiteboard scribble of the WPA key.

vCard QR on the back of a business card

Photographer / consultant prints a stack of business cards with a centered vCard QR. Clients tap-and-scan the card, the contact lands in their phone's address book with the right title, phone, email, and website filled in. The H error correction level keeps the symbol scannable even with a small studio logo overlaid in the middle.

Conference badge bulk-export

Event planner extends the template with a CSV-upload mode that takes a list of attendees and emits one PNG per row — one prompt to add. Print pipeline takes those PNGs directly into the badge template, every attendee gets their own scannable vCard.

Why FloopFloop fits qr code generator projects

Hosted QR services exist because the qrcode library is tiny and someone wrapped it in a marketing site with a payment gateway. The unique thing FloopFloop ships is the visual — a CRT phosphor terminal with horizontal scanlines, beveled square-corner buttons, and IBM Plex Mono throughout. The five colour variants (amber, green, red, cyan, magenta) read like the lit screens of a 1989 arcade rather than a 2024 SaaS dashboard. If that's not your taste, the entire CSS layer is one prompt away from whatever does — the rest of the tool is the same qrcode library every paid service is built on.

Build a QR code generator with four payload types: URL, plain text, WiFi network (SSID + password + WPA/WEP/open + hidden flag), and contact card (vCard 3.0). Live canvas preview that re-renders on every keystroke. Size slider and error-correction level toggles (L/M/Q/H). Download buttons for PNG and SVG. Visual: CRT phosphor terminal — black background with horizontal scanlines, amber glow on every text element, beveled square-corner buttons, IBM Plex Mono throughout. No light mode.

Create a QR code maker for sharing WiFi networks. Single-page form with SSID, password, encryption type (WPA / WEP / open), and a 'hidden network' checkbox. Generate the WIFI:T:... payload correctly with backslash-escaped reserved characters. Live preview and one-click download as PNG so the operator can print and stick the code on the fridge.

Build a vCard QR generator for event badges. Form for name, organisation, title, phone, email, website, and optional address. Encode as vCard 3.0 with empty fields skipped (so the QR stays small enough to print at conference-badge size). Default error correction H so a centered logo overlay still scans. Bulk-export mode that takes a CSV of attendees and emits one PNG per row.

Build a QR code generator with theme switching. Encode URL, text, WiFi, or contact card. Five visual variants — amber CRT, green VT100 phosphor, red-alert arcade, cyan synthwave, magenta neon — controlled by a single CSS variable for the phosphor colour. Same monitor + bevel + scanline pattern across all of them so the design holds together.

常见问题

How is this different from a hosted QR generator like QRCodeMonkey or QRServer?
Hosted services log every payload you encode — convenient for them, awful for you if you're encoding a guest WiFi password or a private link. The version FloopFloop generates runs the qrcode library entirely in your browser; the only outbound surface is the /api/health probe. There's no analytics, no per-encode count, no payload retention. You can also customise the visual to anything you want — most hosted services lock the colour and layout behind a paid tier.
Which payload types does it support out of the box?
URL (bare hosts get https:// prepended automatically), plain text passed through unchanged, WiFi (WPA / WEP / open, with hidden-SSID flag and the correct MeCard-style escape for `;` `,` `:` `\"` `\\` so the WIFI: string round-trips on a phone camera), and Contact (vCard 3.0 with full name, organisation, title, phone, email, website, and optional address). Adding a fifth payload type is one prompt — ask for SMS, mailto:, geo:, calendar event, etc.
What's the error correction level for?
Higher correction lets the symbol survive damage or partial overlays at the cost of denser pixel-grid. L = 7% recovery (densest, fastest to scan); M = 15% (default — fine for almost anything); Q = 25% (tolerates dirt or a small sticker); H = 30% (tolerates a centered logo overlay). Pick H if you plan to drop a small logo into the middle for branding.
Will the QR work when printed?
The PNG download is rendered at max(your size, 600px) so even a small on-screen preview prints crisply. The SVG download is lossless and scales to billboard size without pixelation. Phone cameras need around 2cm × 2cm at arm's length for reliable scanning; plan a quiet zone (empty margin) of at least the size of four QR modules around the code if you're embedding it in a design.
Can I add a logo in the middle?
Out of the box no — the canvas renders the symbol cleanly with no overlay. Ask the AI to add a logo-overlay step that uses the H error correction level and draws an image scaled to ~20% of the canvas in the centre after the QR is rendered. The H level's 30% recovery margin absorbs the obstructed modules so the code still scans.
Is my QR data sent anywhere?
No. All encoding happens in your browser using the qrcode npm library — the payload string, the colours, the EC level, none of it touches a server. The page is set to `force-static`, so it's literally a CDN-cached HTML+JS bundle with no API call other than /api/health (which doesn't see your data).
