Frequently Asked Questions
What is a QR code and how does it work?▼
A QR code (Quick Response code) is a two-dimensional barcode that can store various types of information like URLs, text, contact details, WiFi credentials, and more. When scanned with a smartphone camera or QR scanner app, it instantly decodes the embedded data and can trigger actions like opening a website, adding a contact, or connecting to WiFi.
QR codes work by encoding data into a pattern of black and white squares. The three large squares in the corners help scanners detect the code's position and orientation.
Is CodeCraft really free? Are there any hidden costs?▼
Yes, CodeCraft is 100% free with no hidden costs, subscriptions, or premium tiers. You can generate unlimited QR codes and barcodes, use all customization features, export in any format, and access bulk generation—all without paying anything or creating an account.
Do I need to create an account to use CodeCraft?▼
No account required! CodeCraft works entirely in your browser without any signup, login, or registration. Your generation history is saved locally in your browser's storage, giving you full control and privacy.
Is my data private and secure?▼
Absolutely. All QR code and barcode generation happens entirely in your browser using client-side JavaScript. Your data never touches our servers—we don't collect, store, or transmit any information you enter. Your generation history is stored locally in your browser's IndexedDB, and only you have access to it.
This privacy-first approach means your sensitive data (WiFi passwords, contact info, URLs, etc.) remains completely private.
What file formats can I export my QR codes in?▼
You can export your QR codes and barcodes in three formats: PNG (raster image, great for digital use and print), SVG (vector format, perfect for scaling to any size without quality loss), and PDF (ideal for documents and professional printing). You can also print directly from your browser.
Can I customize the colors and style of my QR code?▼
Yes! CodeCraft offers extensive customization options including foreground and background colors, gradient effects (linear and radial), corner styles (square, dot, rounded), pattern styles (classic, rounded, dots, classy), logo embedding, size adjustment, and error correction levels. You can create QR codes that match your brand identity.
What is error correction and which level should I use?▼
Error correction allows QR codes to remain scannable even if part of the code is damaged or obscured. There are four levels:
- Low (L) - 7% recovery: Smallest code, use for clean environments
- Medium (M) - 15% recovery: Balanced option, good for most uses
- Quartile (Q) - 25% recovery: Better durability for outdoor use
- High (H) - 30% recovery: Best for logos or environments where damage is likely
If you're embedding a logo in your QR code, use Q or H level for reliable scanning.
Can I generate multiple QR codes at once?▼
Yes! Use our bulk generation feature to upload a CSV file containing multiple entries and generate hundreds or even thousands of QR codes at once. All generated codes are packaged into a convenient ZIP file for download.
Will my QR codes expire or stop working?▼
QR codes generated with CodeCraft never expire. Since the data is embedded directly in the QR code image itself (not stored on a server with a redirect link), your codes will work forever as long as the data remains valid. For example, a URL QR code will work as long as that website exists.
What QR code types does CodeCraft support?▼
CodeCraft supports all major QR code types including: URLs, plain text, email addresses, phone numbers, SMS messages, WhatsApp messages, WiFi credentials (with automatic connection), vCard contact info, geographic locations, and calendar events. Check out our templates page for quick generation.
