QR Code Generator
Generate custom static QR codes instantly, and for FREE!
How to Use the QR Code Generator
1. Enter your URL or text – Type (or paste) the website address, text, or any data you want to turn into a QR code in the “Type/Paste your URL” field.
2. Choose a style – Select a dot shape (Square, Dots, Rounded, etc.) and a corner shape from the dropdowns to give your QR code a unique look.
3. Pick a colour – Click the colour circle to choose any colour, or type a hex code (like #ff5722). You can also click any of the colour swatches below for quick, beautiful presets.
4. Set a background – The background colour defaults to white. Change it if you want a different background, just like the foreground colour.
5. Add your logo (optional) – Click “Choose File” and upload your logo or icon. It will appear centred inside the QR code with a safe margin – perfect for branding.
6. Choose a size – Before you download, use the “QR Code Size” dropdown on the right to select the final pixel dimensions (200×200 up to 500×500).
7. Download – When you’re happy with the preview, click Download PNG to save the QR code image to your device.
Tips
- Always test your QR code by scanning it with your phone before printing or sharing.
- If you change your mind, just adjust any setting – the preview updates instantly.
- No data is ever uploaded; everything happens right in your browser.
🔒 We never store or share your QR codes.
All generation happens instantly inside your browser.
If you ever need the same code again, just come back and create a new one – it’s always free.
The Science of 2D Matrix Codes & Error Correction
Quick Response (QR) codes are two-dimensional matrix barcodes that store data both horizontally and vertically. Unlike traditional linear barcodes that can only hold up to 20 characters, a standard QR code can store up to 7,089 numeric characters or 4,296 alphanumeric characters.
Our generator utilizes standard Reed-Solomon Error Correction algorithms. This mathematical framework allows the generated QR code to sustain physical damage, dirt, or tearing up to a specific percentage threshold while remaining fully scannable by optical camera sensors:
Level L (Low): Recovers up to 7% of damaged data.
Level M (Medium): Recovers up to 15% of damaged data (Standard baseline configuration).
Level Q (Quartile): Recovers up to 25% of damaged data.
Level H (High): Recovers up to 30% of damaged data (Ideal for rugged environmental use or adding custom logos).
Common Practical Applications for QR Technology
URL Redirection: Instantly bridge the physical world to digital assets by routing smartphone users directly to landing pages, documentation, or digital menus.
Wi-Fi Network Credentials: Generate an encrypted string containing network SSIDs and passwords, allowing guests to join secured local networks without manual alphanumeric entry.
vCard Digital Business Cards: Store comprehensive professional profile elements (Name, Designation, Phone, Email, Address) directly inside a localized static vector map.
Two-Factor Authentication (2FA): Encode cryptographic seed keys utilizing standard TOTP protocols to synchronize secure authentication software like Google Authenticator.
Frequently Asked Questions (FAQ)
Do the QR codes generated on Convertikon expire? No. All codes generated across our platform are entirely static. The raw text data is hardcoded directly into the matrix architecture, meaning the code functions permanently as long as the underlying destination URL or data remains active.
Are there limits on how many scans my QR code can receive? Not at all. Convertikon offers unlimited usage without hit limits, tracking limits, or mandatory account creation requirements.
Is user data tracked when scanning these QR codes? No. Because our application generates static structures, we do not monitor, capture, track, or intercept analytics data or user tracking pixels. Your absolute privacy and data integrity are structurally guaranteed.
