How to Create and Export Custom QR Codes & Barcodes
- Select Studio Mode & Payload Type: Choose between QR Code Studio, Barcode Studio, or Batch Mode. For QR codes, select your data format (Website URL, Wi-Fi credentials, vCard contact, email, or text). For barcodes, select your standard symbology (e.g. Code 128, EAN-13, UPC-A).
- Customize Visual Styling & Colors: Tailor module dots, corner eye shapes, color palettes, or linear/radial gradients. Optionally upload a logo or add a "SCAN ME" frame. Check the live contrast ratio indicator to ensure readability.
- Preview & Download: Inspect the live vector preview on the canvas. Select your desired output format (Vector SVG, High-Res PNG, JPEG, or Print PDF) and click download. Always test scan before printing!
QR Codes vs Barcodes: Symbology Comparison
| Feature | 2D QR Code (Quick Response) | 1D Linear Barcode (Code 128 / EAN / UPC) | 2D Data Matrix / Aztec |

| Scanning Direction | Omnidirectional (360° from any smartphone camera angle) | Horizontal linear sweep (red laser or 1D camera) | Omnidirectional (2D camera sensor) |
| Error Correction | Built-in Reed-Solomon (7% to 30% data recovery) | Modulo checksum check digit only; no visual recovery | Built-in Reed-Solomon (ECC 200 standard) |
| Primary Use Cases | Website links, Wi-Fi access, digital menus, business cards | Retail checkout, point-of-sale (POS), warehouse cartons | Small electronic parts, healthcare pills, ticketing |
Scanning Reliability & Contrast Best Practices
Maintain the Quiet Zone Margin
Every QR code and barcode requires a clear border (quiet zone) of at least 4 modules width around its edges. Never crowd artwork, text, or borders right up against the modules, as this prevents camera decoders from identifying symbol boundaries.
Ensure High Color Contrast (4.5:1+)
Optical scanners read light reflection. Always keep modules significantly darker than the background (e.g., dark blue on white). Inverted codes (light modules on dark background) fail on older laser scanners and budget smartphone cameras.
Frequently Asked Questions
Are QR codes and barcodes generated on Toolaska completely free?
Yes, 100% free with unlimited generation and downloads. No accounts, subscriptions, watermarks, or hidden paywalls are required.
Do these QR codes ever expire?
No! All QR codes generated here are static QR codes. The encoded text, URL, or Wi-Fi credentials are baked directly into the visual pattern without routing through any redirect server. As long as your destination URL or data exists, the code works forever.
Is my Wi-Fi password or contact information sent to your server?
Never. All generation, encoding, and vector rendering happen strictly in your browser using client-side JavaScript. No data is stored, logged, or uploaded to any server.
Which file format should I use for commercial printing?
We strongly recommend SVG (Scalable Vector Graphics) for commercial print, packaging, and graphic design software (such as Adobe Illustrator or Figma). For office printing, our PDF print sheet export provides crisp vector lines with pre-set margins.
Can I use generated EAN-13 and UPC-A barcodes for retail store checkout?
Toolaska generates valid, standards-compliant barcode symbologies with verified checksums. However, commercial retail products require official barcode numbers registered through GS1 to ensure global uniqueness. You can use our tool to generate high-resolution vector artwork from your licensed GS1 numbers.
