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.
Static vs. dynamic QR codes — what's the difference?
A QR code is a two-dimensional barcode (ISO/IEC 18004) that encodes data as a matrix of black and white squares, readable by any smartphone camera. There are two types: static QR codes, which embed the data directly in the pattern, and dynamic QR codes, which redirect through a server URL that can be edited later.
ToolStack generates static QR codes. That means the destination is baked directly into the code — there is no server in the middle, no redirect, and no expiry date. If you need a QR code for a URL that will never change, a WiFi password, a contact card, or any fixed piece of data, static is the correct choice. The code will work in 10 years exactly as it does today.
| Feature | Static QR (ToolStack) | Dynamic QR (most paid tools) |
|---|---|---|
| Expiry | Never expires | Expires if subscription lapses |
| Privacy | 100% private — no server | Scans tracked by provider |
| Cost | Free forever | Monthly subscription |
| Content editable after print | No (reprint required) | Yes |
QR code error correction — what Level H means
QR codes have four error correction levels defined by the ISO/IEC 18004 standard: L (7% recovery), M (15%), Q (25%), and H (30%). ToolStack uses Level H by default, which means up to 30% of the code can be physically damaged or obscured and the scanner can still recover the full data. This is the highest available level — the best choice for print, stickers, and anything that might get worn or dirty.
