A QR (Quick Response) code is a two-dimensional barcode that can store URLs, text, contact information, WiFi passwords, UPI payment links, and more. Smartphones can scan them instantly using the camera app, making them a powerful bridge between physical and digital worlds.
Select your QR type (URL, WiFi, vCard, WhatsApp, UPI, email, or phone), customize colors and style, click Generate, then download or copy. Print them on business cards, flyers, products, posters, menus, invoices, or share them digitally via email or social media.
Branded QR codes with your logo and colors are more trustworthy and memorable than plain black-and-white codes. They improve recognition, reinforce brand identity, and help your QR code stand out in ads, packaging, and social posts.
Restaurants use them for digital menus. Retailers print them on packaging. Events use them for ticketing. Real estate agents attach them to listings. Marketers include them in ads. Students use them for projects, while businesses use them for WhatsApp, UPI, and contact sharing.
QR codes themselves are safe — they simply store data. Always verify the destination URL before visiting. FlexQR generates all codes client-side in your browser, so no data is sent to any server and your content stays private.
For print, the minimum size is 2×2 cm (0.8 inches). For billboards and outdoor signage, use larger sizes. Always maintain a quiet zone (white border) around the code. Use error correction level H for logos and frames to improve scan reliability.
Yes — FlexQR is completely free to use with no hidden fees, no account required, and no watermarks. All processing happens in your browser, so your data stays private.
Absolutely. Go to the Logo tab, upload your logo image, adjust size and background, and set error correction to H. The QR code will remain scannable because modern QR codes can recover up to 30% of damaged data.
SVG is a vector format that scales to any size without losing quality — perfect for print, signage, and large-format applications. PNG is a raster format great for web, social media, and digital uses. For professional print, always use SVG.
Static QR codes (like those created by FlexQR) never expire — they're just encoded data. The information encoded in the QR will always be readable. If you link to a website, the QR works as long as that URL is live.
Use M (Medium) for standard QR codes — it's a good balance between data capacity and reliability. Use H (High) when adding a logo, as it allows up to 30% of the code to be obscured. Use L (Low) only when the code will be printed in perfect conditions and you need maximum data capacity.
