Free QR code generator online: no sign up, no watermark

A QR generator turns a URL, text, vCard, WiFi network or email into a scannable matrix of pixels. It's used to send users to a website without typing, show a restaurant menu, connect to local WiFi or share your contact card digitally.

A QR code (Quick Response) is a matrix of black and white square dots that a phone reads with its camera in under a second. It encodes any data (a URL, a contact, WiFi credentials or text) without the user having to type anything. Created by Denso Wave in 1994 to track car parts, today they are used in restaurant menus, posters, business cards and product packaging.

A QR code stores: website URL, plain text (up to 4,296 alphanumeric characters), vCard contact (name, phone, email, company, address), WiFi credentials (SSID, password, encryption type), email address with subject, phone number for SMS with pre-filled text, and geolocation coordinates.

No. You generate, download and use static QRs without creating an account. Sign up is only required for dynamic QRs and to keep scan history.

Open the codigo-qr.es QR generator, pick a type (URL, text, vCard, WiFi, email or SMS), enter your content, tweak colors if you want and download the file as PNG or SVG. We don't ask for email or account, no watermark, no usage cap.

Static QR codes are free on codigo-qr.es: no sign up, no watermark and unlimited downloads. For businesses that need to change the destination or see analytics, the Pro plan costs 5,99€/month. The free plan also includes 2 active dynamic QRs to try the full functionality.

No. Neither on free nor on Pro. The QR belongs only to the customer. The only optional element is CTA frames like "SCAN ME" that can be turned on or off.

Yes. codigo-qr.es is available in Spanish, English, Catalan, Portuguese (Brazil), French and German. QR codes encode exactly what you type, including UTF-8 characters: Chinese, Arabic, Cyrillic, emojis or any language work without issues.

Yes. Static QR generation runs entirely in your browser, we don't send your data anywhere. Dynamic QRs are stored encrypted in Supabase with per-user access policies, and payments go through Stripe.

codigo-qr.es offers unlimited static QR codes with no sign up or watermark, dynamic QRs with editable destination and scan analytics, and 8 barcode formats. Static QR generation runs in the browser without sending your data to any server.

On iPhone with iOS 11 or later, open the native Camera app, point it at the QR code and wait a second. A yellow notification appears at the top of the screen with the link or action. Tap the notification to open it. No extra app needed.

On Android 9 or later, open the native camera and point it at the QR. Most models detect it automatically and show a notification with the link. If it doesn't work, look for a 'Scan QR' option in camera settings, or use Google Lens, which comes pre-installed on many Android devices.

On iPhone: open the photo in the Photos app, long-press the QR and a menu appears with 'Open link'. On Android with Google Lens: open Lens, select the image from the gallery and tap the QR. You can also use the Google app to search by image, or third-party apps like QR & Barcode Scanner that support loading photos directly.

Yes. The codigo-qr.es online QR reader decodes any QR or barcode from an image, camera or clipboard. Works on mobile and PC, no sign-up required and no data leaves your browser.

Scan it with the native camera on at least one Android and one iPhone, and also test it in low light or printed small. If you are doing a large print run, print one test copy at the final size and material before ordering the full batch.

Yes, on Pro. You can place your company logo at the center, set brand colors, choose dot shapes (square, rounded, dots or lime to cyan gradient) and corner shapes. Free plan covers foreground and background colors, the rest is part of Pro.

Go to the free QR code generator at codigo-qr.es, choose the type (URL, vCard or WiFi), customize color and logo with Pro plan, and download as PNG or SVG with no watermark. For business use, dynamic QRs let you change the destination without reprinting and show scan analytics by country and device.

Yes. Create a URL QR with the link wa.me/XXXXXXXXXXX (no + or spaces). When scanned, the phone opens WhatsApp with that number ready to message. You can add a pre-filled text with wa.me/XXXXXXXXXXX?text=Hello.

A QR code is two-dimensional: it stores up to 4,296 alphanumeric characters in a square dot matrix and supports URLs, text and contact data. A barcode is linear: it stores 8 to 80 characters in vertical bars and is used in retail, logistics and inventory control.

The full URL is enough, including https://. If you want to track where scans come from, add UTM parameters (utm_source, utm_medium, utm_campaign) or use a dynamic QR code with built-in analytics instead of manual UTMs.

No limit. The SVG download is vector and scales to any size without pixelation, from business card to billboard.

Use the SVG format. SVG is vector, doesn't pixelate and prints crisp at any size from a business card to a billboard. If you need PNG for web or WhatsApp, we also export at 1024x1024 px.

Rule of thumb: 1cm of QR per 4 meters of reading distance. For a restaurant table, 3x3cm is plenty. For a 5m poster, at least 12x12cm. If you add a center logo, raise error correction to H to keep readability.

It is the ability of the code to recover data even if part of the QR is damaged. There are 4 levels: L (7%), M (15%), Q (25%) and H (30%). Use M or Q for general use. Always use H for QR codes with a central logo so the code keeps scanning even when the logo covers part of the data.

Yes. Any modern phone's native camera scans the QR. No specific app needs to be installed.

A static QR carries the URL inside the code: if you want to change the destination you reprint everything. A dynamic QR points to a short link codigo-qr.es/r/abc you manage from the dashboard: change the destination URL anytime and the printed QR keeps working.

A dynamic QR points to an intermediate URL managed by codigo-qr.es. When someone scans, it redirects to the real destination. If you change the destination, the printed QR keeps working because the printed URL stays the same.

As long as the account is active. On free you can have up to 2 active dynamic QRs at a time. On Pro they're unlimited and never expire.

Total scans, country and city, device type (mobile, tablet, PC), browser and exact time. On Pro the history is full, on free the last 7 days.

A QR tracking service logs every scan: country, city, device, time and cumulative total. codigo-qr.es includes analytics from the free plan (last 7 days) and with Pro plan you get full 12-month history, comparison with the previous period and CSV export.

The most complete dynamic QR code platforms offer: editable destination without reprinting, scan analytics (country, device, time), logo and color customization, and vector SVG download. codigo-qr.es is the only one that also generates 8 formats of 1D barcode from the same account.

Use a static QR code for data that will never change, like a contact card or a fixed WiFi network. Use a dynamic one if you are printing it on a long-lasting surface (posters, packaging, vinyl) and want to change the destination or track scans without reprinting anything.

Yes, anytime from the dashboard. Dynamic QRs created during Pro keep working until the end of the paid period.
