Download & use
Download as PNG for web and digital use, or SVG for print and signage. No watermark, no account, no expiry.
FEATURES
Why ToolStack QR beats the rest
Codes never expire
No server redirect means no expiry. The QR code is the data — not a link to our servers. Scan it in 10 years and it still works.
SVG download — free
Vector download scales to any size without pixelation. Essential for large print. Most competitors charge for this — we don't.
100% private
Everything happens in your browser. Your URLs, WiFi passwords, and personal data are never sent to any server — ever.
WiFi QR codes
Generate WiFi QR codes that let guests connect with one scan — no typing passwords. Supports WPA, WEP and open networks.
Why most QR codes stop working — and how to avoid it
Most free QR code generators use a redirect model: your QR code doesn't point directly to your URL — it points to their server, which then redirects visitors to your URL. This means when you stop paying, or when the company shuts down, your QR codes stop working. Printed menus, flyers, business cards, and packaging become useless overnight.
ToolStack works differently. Our QR codes are static and direct — the full destination URL (or WiFi credentials, email address, phone number) is encoded directly into the QR code pattern itself. There is no server in the middle. A QR code generated today will scan correctly in 10 years, whether ToolStack exists or not.
The QR code standard (ISO/IEC 18004) supports four error correction levels: L (7%), M (15%), Q (25%) and H (30%). This generator uses level H — the highest available — meaning up to 30% of the code can be damaged or obscured and it will still scan correctly. This is critical for printed QR codes that may get worn, dirty, or partially covered.
For WiFi QR codes, the credentials are encoded in the standard WPA supplicant format (WIFI:T:WPA;S:NetworkName;P:Password;;), which is natively recognised by iOS 11+ and Android 10+ camera apps — no third-party app required. Always use SVG format when printing WiFi QR codes at large sizes to ensure sharp, scannable output.
