WhatsApp click-to-chat QR codes — free static generator, no subscription

Small shops and freelancers often want a WhatsApp click-to-chat QR on a counter sticker, menu, or business card. Hosted QR SaaS products charge ~$49/month for static codes that never change — you can generate the same thing locally in seconds.

The link format

WhatsApp click-to-chat URLs look like:

https://wa.me/15551234567
Enter fullscreen mode Exit fullscreen mode

Optional pre-filled message:

https://wa.me/15551234567?text=Hi%2C%20I%27d%20like%20to%20order
Enter fullscreen mode Exit fullscreen mode

Use your country code without + or leading zeros. Encode the full URL as the QR payload — scanners open WhatsApp directly.

Free browser generator (no account)

Open this page, paste your wa.me link, download PNG or SVG. Everything runs client-side; nothing is uploaded:

https://cdn.jsdelivr.net/npm/toolkitlabs-qr@latest/index.html

Mirror: https://ytinumoc.github.io/toolkitlabs-qr/

  1. Paste https://wa.me/... into the text field
  2. Download PNG for print or SVG for design tools
  3. Test with your phone before printing hundreds

Batch CLI for menus, events, or reseller packs

Need QR codes for every table, SKU, or sales rep? The batch CLI reads a CSV and writes PNG/SVG files:

npx toolkitlabs-qr@latest qr_batch.py sample.csv ./output/
Enter fullscreen mode Exit fullscreen mode

One-time EUR 9 pack (no subscription): https://buy.stripe.com/5kQ9AU8X45LKe3A8S15Ne0i?client_reference_id=devto-whatsapp-qr

Includes qr_batch.py, sample CSV, and a commercial-use license. CC0 web tool stays free.

Print tips

  • Minimum ~2 cm square for reliable phone scans
  • Leave quiet zone (white margin) around the code
  • Matte laminate reduces glare on glossy stickers
  • Put a short label: "Scan to WhatsApp us"

Why not a monthly QR subscription?

Static WhatsApp links do not need analytics dashboards or dynamic redirects. A PNG you control is enough for most cafés, salons, and market stalls. Pay once for batch tooling if you need volume; skip recurring fees for a link that never changes.
