QR Code Generator — Frequently Asked Questions

UnlimitedQRCodes.com is a free, browser-based QR code generator. It creates unlimited QR codes with no account, no login, no watermarks, and no usage limits. All QR code generation happens entirely in your browser — no data is ever sent to any server. It supports URL, WiFi, vCard, and text QR codes, plus bulk generation from CSV files. Used by businesses in 100+ countries.

Visit UnlimitedQRCodes.com. Select your QR code type (URL, WiFi, vCard, or Text) using the tabs. Enter your content. Optionally choose a colour. Click Download to get your QR code as PNG, SVG, or PDF. The entire process takes under 30 seconds. No account or login is required at any stage.

No. UnlimitedQRCodes.com requires zero registration. No email address, no password, no personal information — ever. Open the site, generate your QR code, download it. We have no sign-up form, no email verification step, and no user database.

Yes — completely free with no hidden costs. There are no premium tiers, no subscription plans, no per-code fees, no watermark removal fees, and no feature gates. Every capability — including bulk generation, SVG downloads, PDF export, WiFi QR codes, and vCard codes — is free for everyone, forever.

Unlimited. There are no daily caps, no monthly quotas, and no lifetime limits. Generate one QR code or a thousand — there is no restriction. The bulk generator handles up to 30 codes per CSV batch; run as many batches as you need.

Four types: URL QR codes (any https:// link), WiFi QR codes (SSID + password + security type, supports WPA/WPA2/WPA3/WEP/open), vCard QR codes (name, phone, email, company, title, website in vCard 3.0 format), and Text QR codes (any plain text message, up to 4,296 alphanumeric characters, UTF-8 encoding).

Three formats: PNG (1000×1000 pixels, 96 DPI — suitable for digital use and standard printing), SVG (Scalable Vector Graphics — vector format that scales to any size without quality loss, the professional standard for print production), and PDF (print-ready single-page document).

Yes. The generator works on all modern smartphones and tablets. The interface is fully responsive and touch-optimised. You can generate and download QR codes directly on your iPhone or Android phone.

Yes — completely private. All QR code generation happens entirely in your browser using JavaScript. No data — URLs, WiFi passwords, contact details, or text messages — is ever transmitted to our servers. We have no server-side processing for QR generation. We do not store, collect, or share any information you enter.

Yes — GDPR compliant by design under Article 25 (Data Protection by Design and by Default). All processing happens in the browser with zero server-side data transmission. We collect no personal data, use no tracking cookies for QR generation, and maintain no database of generated codes. There is nothing to be GDPR-compliant about because no data is processed.

Yes. UnlimitedQRCodes.com collects zero personal information. Under CCPA, businesses that do not collect or sell personal information have no CCPA obligations. We have no user database, no ad tracking tied to user identity, and no data monetisation.

Yes — PIPEDA compliant by design. All QR generation is local to the user's browser. No personal information is collected, transmitted, or stored. This zero-data-collection approach satisfies PIPEDA's core requirement: collect only what you need, and we collect nothing.

Yes. The Australian Privacy Act 1988 and its 13 Australian Privacy Principles (APPs) govern personal information handling. UnlimitedQRCodes.com collects zero personal information — all processing happens in the browser — satisfying the privacy principles by eliminating the need to apply them.

Yes. Your WiFi password is encoded entirely in your browser and stored inside the QR code image itself. It is never transmitted to our servers. We have no record of your WiFi credentials. The security consideration is physical: your QR code image contains the password, so treat the printed or digital file accordingly.

We use no tracking cookies for QR code generation. Standard analytics cookies (Google Analytics) may be present for site usage analytics, but these are separate from the QR generation process and do not capture QR code content.

No. Your QR codes are generated and exist only in your browser's memory and on your device after download. We have no server-side database of generated QR codes. Once you close the tab, nothing persists on our systems.

A URL QR code encodes a website address (https:// link). When scanned by any modern smartphone camera, the phone's browser opens the linked page automatically. URL QR codes are the most widely used type — used for restaurant menus, business card links, product pages, event registration, and marketing campaigns.

A WiFi QR code encodes your network name (SSID), password, and security type in the WiFi QR format (WIFI:T:WPA2;S:NetworkName;P:password;;). When a smartphone scans it, the phone prompts the user to join your WiFi network — no typing required. Works natively on iPhone (iOS 11+) and Android (Android 10+).

A vCard QR code encodes contact information in the vCard 3.0 format. When scanned, the phone prompts the user to save the contact directly to their address book. Fields include: name, phone, email, company, job title, and website. Works natively on all modern smartphones without any app.

A text QR code encodes a plain-text message. When scanned, the text appears directly on the phone's screen — no internet connection required. Used for product serial numbers, instructions, promo codes, and personal messages. Maximum capacity: approximately 4,296 alphanumeric characters (UTF-8 encoding).

WPA/WPA2 (the standard for all modern routers, most common), WPA3 (newest routers, 2019+), WEP (older routers, generally avoid), and None (open networks with no password). Select WPA/WPA2 for the vast majority of home and business routers.

First Name, Last Name, Phone Number, Email Address, Company/Organisation, Job Title, and Website URL. All fields are optional — fill in as many or as few as you need. The vCard 3.0 format is universally compatible with all modern smartphones.

Yes — use the URL tab. For email: paste a mailto: link (e.g., mailto:hello@yourbusiness.com?subject=Enquiry). For phone calls: paste a tel: link (e.g., tel:+14155551234). Include the full international country code for phone links. When scanned, the phone opens the email app or dialler pre-filled.

Yes — use the URL tab. Your WhatsApp link format is https://wa.me/[country-code][number]. For a UK number: https://wa.me/447911123456. For India: https://wa.me/919876543210. Add a pre-filled message with ?text=Hello%20there. When scanned, WhatsApp opens with your number ready to message.

The Bulk tab accepts a CSV file with up to 30 rows. Each row generates one QR code. Your CSV needs at minimum two columns: a Label column (used for naming each code in the PDF and ZIP output) and a Data column (the URL, text, or content for each code). Upload the CSV, preview the codes, and download as a PDF grid or ZIP of PNG files.

30 QR codes per CSV batch. For larger quantities, split your list into multiple CSV files of up to 30 rows each and run each batch separately. Each batch downloads within seconds.

Yes — completely free. UnlimitedQRCodes.com is the only free QR code generator that offers bulk CSV generation. All competitors (QR Tiger, Bitly, Adobe Express, Canva) require paid subscriptions for any bulk functionality. At UnlimitedQRCodes.com, bulk generation is free with no limits on the number of batches.

A standard .csv file with at minimum two columns: Column A = Label (the name for each code, used in PDF labelling and ZIP filenames) and Column B = URL or data. Export from Excel, Google Sheets, or Numbers as .csv format. No special formatting required.

PDF Grid (a print-ready A4 PDF with 6 QR codes per page, each labeled with its row name from the CSV — hand directly to your print shop) and ZIP of PNGs (individual 1000×1000px PNG files, each named after the label column — use when codes go into different design templates).

Yes. The bulk generator supports all QR types including WiFi. Format your CSV with columns for network name (SSID), password, and security type. Generate a unique WiFi QR code per network — ideal for hotel rooms with different WiFi passwords, multi-floor offices, or restaurant chains with separate guest networks.

PNG (1000×1000 pixels): a raster image format. Use for digital channels — websites, emails, presentations, and social media. Also suitable for smaller print sizes. SVG (Scalable Vector Graphics): a vector format that scales to any size without quality loss. Always use SVG for professional printing — business cards, signage, packaging, banners. PDF: a print-ready single-page document. Use for quick home or office printing.

Always use SVG for professional print production. SVG is a vector format that your designer, print shop, or packaging supplier can scale to any size — from a 1.5cm business card QR code to a 1-metre outdoor banner — without any pixelation or quality loss. Send the SVG file directly to your printer.

For reliable scanning by all modern smartphones: 2cm × 2cm (0.8in × 0.8in) is the absolute minimum. Recommended sizes: table tents = 3cm × 3cm, receipts = 2.5cm × 2.5cm, window stickers = 5–8cm, outdoor signage = 8–15cm, billboards = 15cm+. Shorter URLs produce sparser codes that scan reliably at smaller sizes.

Common causes: (1) Too small — increase to at least 3cm × 3cm. (2) Insufficient contrast — dark QR code on white background is most reliable; avoid light colours like yellow or pale blue. (3) Glossy material causing glare — use matte finish for outdoor use. (4) JPEG format — JPEG compression degrades QR modules; use PNG or SVG. (5) URL changed since generation — regenerate with the new URL.

Yes — use the colour picker to choose any dark colour for the QR modules. The key rule: always use a dark colour against a white or very light background. Dark navy, dark green, dark purple, and dark red all scan reliably. Avoid light colours (yellow, pink, pale blue) — they fail in variable lighting. Contrast ratio of at least 3:1 is required.

Generate your QR code at UnlimitedQRCodes.com and download as SVG. In Canva, go to Uploads > Upload files and import the SVG. Drag it onto your design and resize freely — SVG stays perfectly sharp at any size. This works for business cards, flyers, posters, and any Canva design template.

Yes — UnlimitedQRCodes.com is the best free alternative to QR Tiger. It offers unlimited static QR codes with no watermarks, no account, free bulk CSV generation, free SVG and PDF downloads, and complete browser-side privacy — all features QR Tiger reserves for paid plans ($7/month+).

Three features no other free tool offers simultaneously: (1) Bulk CSV generation free — every competitor charges for this. (2) Browser-side privacy — no URLs, passwords, or contacts transmitted to servers. (3) All QR types free including WiFi and vCard — most free tools only support URL codes. Combined with no account requirement and no watermarks, this makes it the most complete free QR code generator available.

ISO/IEC 18004:2015 — the international standard for QR code specification. QR codes generated by UnlimitedQRCodes.com are fully compliant with this standard and are scannable by all modern smartphones globally, including iOS Camera (iPhone 7+, iOS 11+), Android Camera (Android 10+), and Google Lens.

Static QR codes never expire. A static QR code permanently encodes its content — the code itself will work for as long as its linked URL or content is accessible. UnlimitedQRCodes.com generates static QR codes. Note: if the URL a code links to is taken down or changed, the QR code will no longer reach the intended destination — but the QR code itself does not expire.

Static QR codes permanently encode the destination URL or content in the QR pattern itself — the code cannot be changed after generation. They never expire and require no subscription. Dynamic QR codes use a redirect URL that can be changed without regenerating the physical code, and typically offer scan analytics. UnlimitedQRCodes.com generates static QR codes — free with no account. Dynamic QR codes require a paid subscription from providers like QR Tiger or Bitly.

All modern smartphones: iPhone 7 and newer running iOS 11+ (built-in Camera app), Android phones running Android 10+ (built-in Camera or Google Lens), Samsung phones via Bixby Vision or Camera app, and any phone with a dedicated QR scanner app. QR codes comply with ISO/IEC 18004 — the global standard — ensuring compatibility worldwide.

QR code capacity varies by content type: numeric data (0–9 only): up to 7,089 characters. Alphanumeric data: up to 4,296 characters. Binary/byte data (including most text): up to 2,953 bytes. Kanji characters: up to 1,817 characters. For best scan reliability at small print sizes, keep URLs short and text content under 300 characters.

Browser-side (client-side) processing means the QR code encoding algorithm runs as JavaScript in your browser, with no network requests made during generation. This achieves three things: complete privacy (your data never leaves your device), faster generation (no server round-trip), and zero-data-collection compliance with GDPR, CCPA, PIPEDA, and other privacy laws.
