Generate custom QR codes with logos, custom colors, templates, and high-quality export options.
All QR codes are generated completely inside your web browser. No data, URLs, credentials, or uploaded logos are ever transmitted to our servers, keeping your information private.
A Quick Response (QR) code is a matrix barcode invented in 1994 by the Japanese automotive company Denso Wave. Unlike standard 1D barcodes that encode data horizontally only, QR codes encode data horizontally and vertically, allowing them to store up to 300 times more information (including URLs, contact details, WiFi keys, and text blocks).
QR codes enable "print-to-digital" marketing, turning physical flyers, banners, and billboards into direct digital channels. By adding tracking parameters to target URLs, marketers can monitor scan locations, client devices, and timestamps to calculate the exact ROI of offline advertisement assets.

Yes. You can create unlimited QR codes for free and download them in high-quality formats such as PNG, SVG, PDF, and WebP.
No. Static QR codes do not expire and will continue working indefinitely as long as the linked content or destination remains available.
Static QR codes store information directly inside the code and cannot be edited later. Dynamic QR codes use a redirect link that can be updated after creation.
Yes. You can upload your business logo or brand icon and place it in the center of the QR code while maintaining scan reliability.
For standard QR codes, Medium (M) is usually sufficient. If you add a logo or design elements, choose High (H) or Quartile (Q) for better scan performance.
PNG is ideal for digital use, SVG is perfect for printing and scaling without quality loss, PDF works well for documents, and WebP provides smaller file sizes for websites.
Static QR codes do not include analytics. To track scans, clicks, locations, and devices, you would need a dynamic QR code service with analytics support.
For most printed materials, a minimum size of 2 x 2 cm is recommended. Larger sizes improve scanning distance and reliability.
Yes. Modern iPhone and Android devices can scan QR codes directly using their built-in camera applications without requiring additional software.
The QR code itself can be scanned offline, but online content such as websites, videos, or forms requires an internet connection to open.
Static QR codes cannot be modified after generation because the information is permanently encoded inside the code. You must generate a new QR code if the data changes.
QR codes themselves are safe, but users should only scan codes from trusted sources. Always verify the destination website before entering sensitive information.
Yes. QR codes are commonly used on business cards to instantly share contact details, websites, portfolios, social media profiles, or digital vCards.
Static QR codes will continue pointing to the original URL. If the destination changes, you will need to create and distribute a new QR code.
No. QR codes are generated directly in your browser, and your content is not uploaded or stored on our servers.
