QR Code Generator

A QR code generator that turns any URL or text into a scannable QR code with selectable size (512, 1024) and error-correction level (L/M/Q/H), generated entirely in your browser, with PNG download.

This generator creates a scannable QR code for any text or link in a second — choose a size, pick an error-correction level, generate, and download a crisp PNG ready for print or screen. QR codes are the fastest bridge from the physical world to a URL: on a shop counter, a restaurant table, a poster, a business card, a product label or an invoice, one scan replaces typing an address.

Two settings matter more than they look. Size: 512 pixels suits most digital uses, while print jobs should use 1024 so the code stays sharp when scaled — a blurry QR code is an unscannable QR code. Error correction: QR codes carry built-in redundancy, and the level sets how much of the code can be dirty, damaged or covered while still scanning. Level M (15%) is the everyday default; choose H (30%) if you plan to overlay a logo in the centre or print somewhere the code may get scuffed. Higher correction means a denser code, so very long URLs pair better with lower levels.

Everything happens in your browser — the content you encode is never uploaded, so it's fine for private links and Wi-Fi passwords. One practical tip: prefer short URLs. A shorter address produces a sparser, easier-to-scan code, and lets you use a forgiving error-correction level even at small print sizes.
