What the code actually contains

A WhatsApp QR code is just a QR code whose content is a wa.me link: https://wa.me/ plus your full international number, plus an optional URL-encoded message. Any camera app that reads QR codes will offer to open it in WhatsApp.

Because the content is a plain URL, the code is portable: it does not depend on this tool, it cannot expire, and no third party sits between your customer and your chat. If you ever change your WhatsApp number, generate and print a new code; the old one will keep pointing at the old number.

Worked examples: from a local number to a wa.me link

Most countries write mobile numbers with a leading 0 (the trunk prefix) for calls inside the country. That 0 is not part of the international number, so it never goes into a WhatsApp link. Pick the country, type the number the way you normally write it, and the generator drops the 0 and adds the country code:

• United States (+1): (555) 123-4567 becomes https://wa.me/15551234567. US numbers have no trunk 0, the 1 is the country code.
• India (+91): 098765 43210 becomes https://wa.me/919876543210. Drop the leading 0, keep all ten digits of the mobile number.
• Nigeria (+234): 0803 123 4567 becomes https://wa.me/2348031234567. Drop the leading 0 of the 11-digit local number.
• Kenya (+254): 0712 345 678 becomes https://wa.me/254712345678. Drop the leading 0.
• United Arab Emirates (+971): 050 123 4567 becomes https://wa.me/971501234567. Drop the leading 0.
• United Kingdom (+44): 07700 900123 becomes https://wa.me/447700900123. Drop the leading 0.

If you paste a number that already starts with +, the generator keeps its digits exactly as written, so write it without the trunk 0: +44 7700 900123, not +44 (0)7700 900123.

PNG or SVG: which download to pick

PNG is a pixel image, ready for social posts, documents and most print shops. The download here is generated at high resolution, comfortably sharp for a poster or a sticker.

SVG is a vector file: it scales to any size with perfectly crisp edges, which designers and print shops prefer for large formats like banners and shop windows. If you are not sure, PNG is fine; if someone asks for “vector artwork”, send the SVG.

Adding a logo without breaking the scan

QR codes carry built-in error correction: a portion of the pattern is redundant, so the code still scans when part of it is covered. That is what makes a center logo possible.

When you add a logo here, the generator switches to the highest error-correction level and keeps the logo small enough to stay inside the safe budget. Still, always test-scan the final printed code: dark-on-light codes with a clear quiet zone around them scan best.

Where WhatsApp QR codes work best

• The counter or checkout: “Questions? Scan to chat with us.”
• Product packaging and delivery boxes, so support starts without an email address.
• Storefront windows and posters, reaching people outside opening hours.
• Business cards, brochures, table tents and event badges.
• Vehicle wraps and signage for service businesses.

QR code vs WhatsApp’s built-in contact QR

WhatsApp itself can show a contact QR inside the app, and it works well person-to-person. A generated code like this one has two advantages for business use: you can pre-fill the first message, and you get print-ready PNG or SVG files in any size instead of a screenshot.
