Your content becomes a static QR code, right in this browser.
Inspect the payload. Verify the image. Export your file.

Detection runs here. Your original stays in this box.
Use a stable page you control. The code stays the same, so keep the destination available.

Logo, margin & frame
Processed locally. A logo uses high error correction. Keep it small and test a print.
Logo and margin limits are Tidy QR design safeguards.

A successful image check confirms decoding here, not every phone or print condition. Plan your print size ↗
Scan simulator Six image conditions. One local decoder.
Put this code through a scan test.
Simulation, not a guarantee. Each altered image must decode to your exact payload. These fixed image effects do not model a specific camera or material.
Generate a code, then run the simulation.
How to read this simulation
Each effect starts from a 320-pixel-wide rendering of the current SVG. Small size reduces the artwork to 80 pixels; defocus uses two 5 × 5 box-blur passes; motion averages 11 horizontal pixels; perspective maps the image onto a tilted quadrilateral; low light applies 32% brightness with deterministic noise up to ±22 channel values; glare adds a white radial spot with a radius of 18% of the image width. These are fixed test inputs, not measured environment statistics.
The separate size sweep checks widths of 320, 256, 224, 192, 160, 128, 112, 96, 80, 64, 48, 32, 24 and 16 pixels, including the quiet zone and any caption. It reports the smallest tested width that returned the exact payload, not a physical print minimum or an exhaustive threshold. A pass only describes this decoder and this image. Calculate a print starting point and test the final material with real phones.
Direct by design
Your content goes into the QR code itself. Tidy QR adds no tracking link and sets no expiration timer.
Check before you print
The image is decoded here before export. Then test the final printed piece on the phones and at the distance your audience uses.
Keep the destination alive
A static code cannot change its embedded content. A website link still needs an available page, domain and internet connection.
