Build a QR code for a URL, WiFi network, contact card, WhatsApp message, event, or payment link. Add a logo, pick a frame, and export a print-ready file, all inside this browser tab.
Zitly generates static QR codes using the open-source qrcode library, rendered entirely on the browser's own Canvas API. Nothing you type, including WiFi passwords or contact details, is ever sent anywhere.

13 content types, a live style preview, and watermark-free export.
1. Content type
What should this QR code open or do?
2. Website URL details
3. Customize
Every thumbnail below is a real, live-rendered QR code.

No payment screen appears at any point in this flow.
13 options are available. The form below adjusts to match: a URL gets one field, WiFi gets a network name and password, a vCard gets a small contact form.
Each field is validated as you type. A URL has to start with http:// or https://, an email has to match a real address pattern, so nothing broken makes it into the final code.
Pick a frame from the Style tab, set foreground and background colors in Colors, and upload a logo in Logo if you need one. Every preview is a real, live QR render, not a mockup.
Choose an output size from 200 to 1000 px, and an error correction level. Use Medium by default, and switch to High the moment a logo is involved.
Click Generate QR Code. Scan the on-screen result with your own phone before downloading, then export PNG for screens or SVG for print.
Almost every QR code that fails to scan does so for one of these predictable reasons.
The logo covers modules that Medium's 15% redundancy can't fully recover, and the code stops scanning on a share of phones.
Switch to High (H) before adding a logo. Zitly does this automatically the moment a logo file is uploaded — check the Size tab to confirm it stuck.
Scanners rely on detecting a contrast boundary between dark modules and the light background. Low contrast fails on older phones and in bright outdoor light.
Keep at least a 4:1 contrast ratio. Black on white remains the most reliable pairing across every device.
PNG is a fixed-pixel raster format. Stretching a 400×400 px file to fill a 10 cm print area produces a visibly blurred result that can fail to scan.
Download the SVG version for anything going to a printer. It's vector, so it stays sharp at any physical size.
Most phone cameras struggle to resolve a QR code below roughly 2 cm × 2 cm at arm's length, especially a dense one from a long URL or a full vCard.
Stay at or above 2 cm square for anything handheld. For signage viewed from further away, scale up: 1 cm of code for every 10 cm of expected scanning distance.
Every QR code needs a clear margin on all four sides so a scanner can find the corner finder patterns. Placing other artwork right up against the edge breaks that.
The generator includes a safe margin in every export. If it's placed inside a larger design in Figma or Canva, leave at least 4 mm of clear space around it.
A dynamic code routes every scan through a third-party server. If that service shuts down or a subscription lapses, every code already printed goes dead at once.
Use a static code, the kind this tool makes, for anything printed permanently: business cards, packaging, signage.
A quick reference for common scenarios — pick your settings before you start filling in the form.
| Use case | Type | Format | Error level |
|---|---|---|---|
| Website link on a business card | URL | SVG | M |
| Café or venue WiFi access | WiFi | SVG | M |
| Conference badge contact exchange | vCard | PNG or SVG | M |
| Event flyer with a logo overlay | URL | SVG | H |
| Outdoor product packaging | URL | SVG | Q |
| Instagram bio or story link | URL | PNG 600×600 | M |
| Email signature | URL | PNG 300×300 | L |
| WhatsApp customer service button | PNG or SVG | M | |
| Billboard viewed from 5 m or more | URL | SVG | Q |
L = 7% redundancy · M = 15% · Q = 25% · H = 30%. Higher levels produce a denser pattern.
Every QR code carries redundant data, extra encoded information that lets a scanner rebuild the full pattern even when part of it is dirty, damaged, or covered by a logo. More redundancy means a denser pattern for the same content, since more of the grid is spent on recovery instead of data.
Clean digital displays only, no logo, no physical handling. The smallest, least dense pattern.
Example: A code shown on a controlled digital sign or a screen.
The default for most cases: business cards, flyers, product pages, email signatures.
Example: A plain business card code with no logo.
Outdoor signage or packaging exposed to wear, without needing the maximum density of High.
Example: A transit poster or outdoor banner that might get scratched.
Required whenever a logo is embedded. Also a safe default for heavily handled merchandise.
Example: A branded code with a company logo, printed on event merchandise.
This is one of the most common questions when picking a generator, and the right answer depends entirely on the use case, not on which option sounds more advanced.
In practice: use a static code for anything printed permanently, business cards, packaging, signage, merchandise. Reach for a dynamic service only when post-print URL changes or detailed scan data genuinely matter, and budget for the subscription that keeps it working.
Six of the thirteen types, with what makes each one work and what tends to go wrong.
Landing pages, menus, portfolios, booking forms
Tip: Add UTM parameters to the URL before generating, so scan traffic shows up clearly in your destination site's own analytics.
Avoid: Avoid pointing the code at a short link from another shortener. If that service goes down, every printed code breaks at once — encode the real destination directly.
Cafés, hotels, co-working spaces, short-term rentals
Tip: Place the code at the entrance and near the counter. Android 10+ and iOS 11+ scan and connect without a separate app.
Avoid: Don't print the plain-text password right next to the code if privacy matters — the QR handles the handshake; a visible password defeats the point.
Business cards, conference badges, email footers
Tip: One scan saves a fully-formed contact: name, title, company, phone, email, in one tap. Use vCard 3.0 for the widest device support.
Avoid: Skip embedding a photo in the vCard data — it inflates the code's density and hurts scan reliability at small sizes.
Support desks, feedback prompts, contact pages
Tip: Pre-fill the subject line so replies route correctly without the sender typing anything.
Avoid: Don't use a QR-encoded email link for newsletter signups — spam filters treat a pre-composed mailto link differently from a real form submission.
Customer support triggers, appointment confirmations
Tip: Include a short pre-written message so the customer only has to tap send.
Avoid: Always include the full international country code — the wa.me link fails silently without it.
Conference sessions, launches, local meetups
Tip: Scanning adds the event straight to the phone's calendar, no retyping dates or venue details.
Avoid: Double-check the timestamp format before generating — an invalid one creates an event at the wrong time or fails without warning.
Specific applications across three sectors that use QR codes daily.
A code that fails to scan after printing is rarely a generation problem — it's almost always a sizing or material decision made after export.
Direct answers on watermarks, logos, error correction, and file formats.
Yes. Every download is watermark-free, with no account, no paid tier, and no cap on how many codes you make.
No. This tool creates static codes — the destination data is encoded directly into the image, with no redirect server involved on Zitly's side, so nothing about the code itself can expire.
Yes, as long as error correction is set to High (30% redundancy). The tool switches to High automatically the moment a logo is uploaded.
About 2 cm × 2 cm minimum for handheld scanning. For anything viewed from further away, scale up using a 1:10 ratio between code size and expected scanning distance.
PNG for screens: websites, email, social posts. SVG for print — it's vector, so it stays sharp at any physical size, from a business card to a banner.
No. Generation runs in the browser using the open-source qrcode library. WiFi passwords, contact details, and everything else you type stay on your device.
Medium (15%) covers most everyday cases. Move up to Quartile (25%) for anything exposed to wear, and use High (30%) whenever a logo is involved.
Static, the kind this tool makes, for anything printed permanently. Dynamic only if you genuinely need to change the destination after printing or want click analytics, and are willing to keep paying to maintain it.
No signup screen. No watermark on the download. Just a QR code.
Shorten any URL instantly. Browser history, QR export, zero server tracking.
Generate EAN-13, Code 128, UPC, and 15+ barcode formats with full styling.
