Free QR Code Generator

A QR code generator is one of the most useful everyday tools for businesses, marketers, and creators. Menus, packaging, business cards, event posters, WiFi login cards, and product labels all carry QR codes that connect the physical world to a URL. But most so-called 'free' generators bury the essentials behind signups, watermarks, or expiration dates. OpenToolLab is a free QR code generator with no sign up and no expiration — exactly what a free tool should be.

Creating a code takes seconds. Paste any URL or text into the generator and the QR code updates live as you type, so you always know exactly what you're encoding. Need a WiFi login card? Switch to WiFi mode and enter the network name, password, and encryption — scanning it connects a phone instantly. Building a contact or promotion flow? Email mode produces a pre-filled mailto code from an address, subject, and body.

Design control is where this generator stands apart from the basic tools. Choose a module shape — sharp squares, rounded squares, or modern dots — and set foreground and background colors to match your brand. Upload a logo or icon and it is placed in the center with the error-correction level automatically raised so the code still scans from every angle. An optional label below the QR makes the printed asset clearer for customers.

Export is fully open: download a PNG for social posts, a vector SVG for crisp print, or a print-ready PDF. Every download is high resolution and watermark-free. Because generation runs 100% in your browser, nothing you type or upload is ever sent to a server. You can verify this yourself in your browser's Network tab — generating and downloading makes zero network requests.

Your downloaded code is yours forever. It is a normal image or PDF file on your device, so it cannot expire, be disabled, or start showing a watermark later. Many paid 'dynamic QR' services charge monthly for what is actually just a static code with an expiry countdown. With OpenToolLab, print your menu, poster, packaging, or business card and the code keeps working for years with nothing to renew.

OpenToolLab's QR code generator is the free, private, no-expiration alternative to branded and gated tools. No account to create, no watermark on your downloads, no codes that stop working after a trial. Generate a custom QR code with your colors and logo, print it or share it — all for free, with no sign up required.
