QR Code Encoder & Decoder
Generate custom QR codes from text or URLs and decode QR images locally in your browser with private, browser-only processing and export controls.
Generate custom QR codes from text or URLs and decode QR images locally in your browser. No uploads, no tracking, and no account required.
Decode QR from Image
Custom QR Generation
Generate QR codes from arbitrary text and URLs with control over size, margin, colors, and error-correction level.
Local QR Decoding
Decode uploaded QR images directly in-browser using native barcode detection when available, avoiding remote scanners.
Private Browser-Only Workflow
Both encoding and decoding run locally on your device. QR content and uploaded images are never sent to external servers.
Free and Unlimited
Generate and decode as many QR codes as needed without signup, quotas, or usage restrictions.
Share URLs Fast
Convert product pages, login links, or documentation URLs into scannable QR codes for mobile distribution.
Event and Access Flows
Generate QR payloads for check-in, Wi-Fi onboarding, and handoff instructions used in operational workflows.
Printed Material QA
Decode QR images from screenshots or exports to confirm printed assets point to the correct destination.
Security Review
Inspect suspicious QR images locally before scanning them on a phone, helping reduce unsafe redirect risk.
Marketing Asset Production
Export PNG or SVG QR codes with custom styling for landing pages, posters, and packaging designs.
Internal Tooling
Generate temporary QR encodings for local testing, provisioning flows, and cross-device debugging scenarios.
QR Code Encoder & Decoder provides a browser-based workflow for creating QR codes from text content and decoding QR images back into their raw payloads. It is designed for quick operational use without remote APIs or external scanning services.
Encoding Workflow
The generator produces PNG and SVG output from plain text or URLs with adjustable size, margin, color, and error-correction settings. This makes it suitable for both simple sharing and design-oriented export.
Decoding Workflow
Uploaded QR images are decoded in-browser through native barcode detection when the current browser exposes QR support. This keeps image content local and avoids sending screenshots or assets to third-party services.
Practical Constraints
QR decoding availability depends on browser support for the BarcodeDetector API. When unsupported, encoding remains fully functional while decoding reports the limitation clearly so you can switch to a compatible browser.

Frequently Asked Questions About QR Code Encoder & Decoder
Yes. You can encode website URLs, plain text notes, identifiers, contact payloads, or any other text content into a QR code.
The tool generates a downloadable PNG preview and also exposes SVG markup for vector-friendly export and design workflows.
Encoding works broadly, but decoding depends on browser support for the BarcodeDetector API with qr_code format. If unsupported, the tool reports that limitation clearly.
Yes. You can adjust size, quiet-zone margin, dark/light colors, and error correction level to balance aesthetics and scanning resilience.
No. Generation and decoding are handled locally in your browser, so QR content and uploaded images are not sent to external services by this tool.
Error correction controls how much data can be recovered if a QR code is partially damaged or obscured. Higher levels improve resilience but increase symbol density.
Yes. The tool is free to use without signup and supports unlimited local QR generation and decoding workflows.
