QR Code Generator
Generate SVG & DXF files from URLs. Perfect for 3D printing and laser cutting!
Physical output size in millimeters
Module extrusion height for STL output (in mm)
Higher levels allow the QR code to remain readable even when partially covered or damaged. However, this increases the module count, making it harder to 3D print. Level L is recommended for MakerChip.

About This Tool
This QR code generator does not shorten URLs. It also does not communicate with the server in order to generate QR codes or export data.
Shorter URLs are better
The number of modules (black squares) in a QR code is proportional to the data length. Shorter URLs result in fewer modules, making each module larger and improving print accuracy on FFF 3D printers. Use the shortest URL possible.
URL shortener warnings
URL shorteners like bit.ly or tinyurl make QR codes smaller, but they come with several risks.
- If the service shuts down, your links can stop working.
- Changes to the service configuration or how it is operated could redirect users to unintended pages or insert ads.
- Your click statistics may be shared with the service provider or third parties.
For physically printed QR codes, we strongly recommend using permanent, unchangeable URLs.
Recommended size
For FFF 3D printers, ensure each module is at least 2x your nozzle diameter. With a 0.4mm nozzle, aim for a minimum of 0.8mm per module.
QR Code is a technology born in Japan. It was invented in 1994 by Masahiro Hara at DENSO (now DENSO WAVE INCORPORATED) in Aichi Prefecture, and is now used worldwide. QR Code is a registered trademark of DENSO WAVE INCORPORATED and is standardized as JIS X 0510 and ISO/IEC 18004. While DENSO WAVE holds patents on QR Code, they have declared that they will not exercise their patent rights for QR Codes conforming to the standard, making it freely available for everyone. This spirit of "making technology accessible to all" resonates deeply with the open-source philosophy of the RepRap project.
