Zero signup. Zero database. 100% client-side. Customize colors, gradients, dot shapes, and center logos with instant 4K print exports.
No bloat, no forced subscriptions, and zero tracking. Just clean, high-performance optical engineering in your browser.
Everything is processed inside your browser memory using HTML5 Canvas & WebAssembly. Your Wi-Fi keys, contact cards, and URLs are never sent to a server.
Download pure, clean SVG files ready for Adobe Illustrator, Figma, vinyl cutters, laser etchers, and billboard printers without pixel degradation.
Export raster images at 512px, 1024px, 2048px, or 4096px resolution with crisp edges and perfect anti-aliasing for commercial offset printing.
Design modern QR codes with multi-stop linear/radial gradients, customizable dot shapes (pill, circle, diamond), and independent corner pupil colors.
Adding a center logo automatically boosts error correction to Level H (30%), guaranteeing camera scan reliability despite center occlusion.
Copy high-resolution PNG image blobs directly to your system clipboard to paste effortlessly into Slack, Figma, Word, Canva, or Photoshop.
Verify what your QR code encodes before sending it to the printer with our built-in offline QR code decoder and camera simulator.
Toggle alpha channel transparency with one click to seamlessly overlay QR codes onto dark posters, business card textures, or packaging boxes.
Everything you need to know about optical data encoding, error correction algorithms, vector scalability, and prepress standards for flawless scanning.
Standard QR code platforms often trap you in a monthly subscription by generating redirect links. When your trial ends, your printed posters and business cards stop working.
QrDrop generates permanent static QR codes. The raw payload (URL, Wi-Fi, vCard) is directly woven into the matrix geometry. There is no middleman server, no DNS lookup delay, and zero expiration date.
QR codes use Reed-Solomon algebraic error correction codes (ECC) to reconstruct missing or obscured data. The specification offers four standard levels:
When you add a brand logo in QrDrop, our engine automatically shifts to Level H, ensuring the camera reconstructs 100% of the destination URL despite center occlusion.
Optical scanning follows the 10:1 Distance-to-Size Ratio rule. The minimum physical width of your printed QR code should equal the expected scanning distance divided by 10.
Always download Vector (SVG) or 4K PNG (4096px) to prevent fuzzy anti-aliasing during commercial 300 DPI plate printing.
The two most common reasons QR codes fail in production are low color contrast and missing quiet zones:
