Is my uploaded logo stored on ChatGrow servers?

No. Your logo is processed 100% locally on your computer or phone using HTML5 Canvas and the client-side FileReader API. Neither your logo file nor your WhatsApp business number are ever uploaded or saved on our servers.

What resolution should I download for print banners and flyers?

For small screen uses (social media or website footers), 300x300 or 512x512 pixels is sufficient. For printed retail standees, packaging boxes, and flyers, select 1024x1024 pixels or download the vector SVG format to ensure razor-sharp edges without pixelation.

Why is sufficient color contrast critical for QR scanning?

Optical QR scanners measure the contrast difference between dark modules and light background blocks. If both colors are too similar (e.g. light green on white, or dark grey on black), phone cameras will struggle to decode the code, especially under dim ambient store lighting.

Can I add a pre-filled greeting message to my branded QR code?

Yes! When you input a pre-filled welcome message, it is safely encoded into the QR code. When a customer scans your counter standee or flyer, their WhatsApp chat opens with that message already typed into the input box.

How to Design & Print Branded WhatsApp QR Codes That Scan Reliably

Branded QR codes with custom logos look significantly more professional on retail counters, packaging boxes, and table tents than plain black-and-white grids. However, placing graphics over QR modules requires strict adherence to scanning physics:

Rule 1: Error Correction

Always Use High (H) Mode

Our tool automatically defaults to Level H (High) when a logo is added. This preserves 30% redundant data, ensuring the phone can reconstruct hidden modules under the logo badge.

Rule 2: Color Contrast

Dark Modules on Light BG

Avoid inverted colors (white modules on dark background) whenever possible. Most low-cost Android camera sensors are tuned to expect dark foreground modules on a light background.

Rule 3: Minimum Print Size

At Least 2 x 2 Centimeters

For table tents and packaging, ensure the physical printed QR code is at least 2.5 cm (1 inch) wide. For outdoor banners, size up proportionally to allow scanning from 2–3 meters away.

Recommended Print Dimensions by Physical Use Case

Placement	Scanning Distance	Minimum Physical Width	Recommended Download Size
Product Packaging & Labels	15 – 25 cm	2.0 cm (0.8 in)	512 x 512 px or SVG
Retail Cashier Counter Standees	30 – 50 cm	4.0 cm (1.6 in)	800 x 800 px or SVG
Restaurant Table Tents & Menus	25 – 40 cm	3.5 cm (1.4 in)	800 x 800 px or SVG
Posters, Standees & Roll-ups	1 – 2 meters	15 cm (6.0 in)	1024 x 1024 px or SVG

Frequently Asked Questions

Everything you need to know about creating and printing branded WhatsApp QR codes.

QR codes use Reed-Solomon error correction algorithms. Placing a logo in the center covers up a percentage of the code's data modules. Error correction level 'H' (High) restores up to 30% of obscured or damaged data modules, allowing smartphone camera lenses to decode the WhatsApp link flawlessly despite the central logo graphic.
