LOCAL-FIRST · REAL DECODER · HASH-BACKED

Free QR code generator with a print survival test

Create a static URL, text or WiFi QR code free with no signup. Download a sharp SVG or PNG, model final print size and DPI, and run five local decoder stresses before you print.

01 · INPUT & PRINT MODEL

Enter a link, text or WiFi details

Generate your QR code with five automatic scan checks. The print settings below help you check the size if you plan to print it.

Only complete http:// or https:// URLs.

Choose Generate QR code to create your SVG and PNG downloads and see the results of five automatic scan checks.

WHAT MAKES THIS DIFFERENT

A generator that tries to break its own work

This workflow does not stop at generation. It sends the exact generated bytes through an actual local decoder after five deterministic transformations, then binds the result and export bytes into a Receipt v1.

Generate a standards-shaped QR with a locked four-module quiet zone.
Model dots per module from final millimetres and printer DPI.
Decode original, downsampled, blurred, perspective-shifted and damaged variants.
Export SVG, PNG, CSV, JSON, Markdown, visual board and hash-backed receipt.

STATIC QR · NO EXPIRY SWITCH

A static QR code does not expire on its own

FastTool encodes your URL, text or WiFi details directly into a static QR. There is no FastTool redirect, account or subscription that can switch it off later. A URL QR can still stop working if the destination moves or goes offline; a WiFi QR stops matching when the network name, security type or password changes.

WiFi QR without an account

Choose WiFi, enter the network name and security details, and generate locally. The QR necessarily contains those details, so treat the exported file like the password it encodes and share it only with the intended audience.

HONEST METHOD

Digital preflight, not a physical guarantee

PASS proves only this deterministic digital test profile. It does not verify a printer, paper, ink, lamination, curvature, lighting, camera, scanner app or final placement. Always proof-print at the final size and test with multiple real devices.

The 4% perspective inset, blur, downsample and damage budgets are versioned FastTool simulation settings—not official DENSO or ISO tolerance limits. The evidence pack makes that boundary explicit.
