How this tool helps
Turn printed material into WhatsApp chats
Nobody types a phone number off a flyer. A QR code skips that step: scan, and the chat opens with your pre-filled message, so you also know which flyer or table card it came from.
Use a different pre-filled message for each placement, like "Hi, I'm at table 4" or "Hi, I got your flyer", and you can see which ones bring in chats.
Popular QR Code Placements
- Business Cards: Make it simple for networking contacts to ping you.
- Restaurant Menus: Allow diners to message tableside for billing or orders.
- Product Packaging: Provide quick scan codes for warranty activation or user support.
- Flyers & Storefront Signs: Drive offline foot traffic into online conversions.
- Shipping Inserts: Direct buyers to leave feedback or get coupon links.
How to Color Match Your QR Code
To ensure your QR code scans flawlessly every time:
- Maintain High Contrast: Keep a dark dot color on a light background. Light dots on dark backgrounds (inverted) fail to scan on older phone models.
- Background Color: Pure white (
#FFFFFF) or very light pastels are safest. - Foreground Color: Black, deep forest green (WhatsApp styling), navy, or dark charcoal scan perfectly.

FAQ
Frequently asked questions
Straight answers about using this tool and its output.
How do I create a WhatsApp QR code?
Enter your phone number (including your country code) and optional custom message, then click "Generate QR Code". You can customize the foreground and background colors to match your brand and instantly download the QR code as a PNG or vector SVG file.
Are WhatsApp QR codes dynamic?
Standard QR codes generated from direct URLs are static, meaning the data is coded directly into the QR pattern. If you want to change the number or message, you will need to generate a new QR code. This tool creates static QR codes for free without requiring signup.
What sizes are WhatsApp QR codes best printed at?
For small print items like business cards, a minimum size of 2 x 2 cm (0.8 x 0.8 inches) is recommended. For larger media like flyers, store windows, or product packaging, print the QR code larger. Ensure high contrast (e.g. dark dots on a light background) so all phone scanners can read it.
Can I add my logo to this free QR code?
This generator specializes in high-speed, custom color WhatsApp QR code creation. For advanced logo placement, you can download the vector SVG output from our tool and overlay your logo in design software like Canva, Figma, or Adobe Illustrator.
Do these QR codes expire?
No. The QR codes generated by Zynfo.ai are permanent and will never expire. Since they direct to standard WhatsApp chat URLs, they will remain active as long as the phone number is active on WhatsApp.
