NoTraQR lets you download your QR code in three different file formats: PNG, SVG and STL. Each serves a different purpose. Choosing the right format ensures your QR code looks sharp in every context.
PNG (Portable Network Graphics) is a raster image format. This means the image is made up of a fixed grid of pixels. The resolution is set at the time of generation — NoTraQR offers 200 px, 300 px, 400 px and 600 px options.
Use PNG when: you are embedding the QR code in a website, email, presentation or digital document. PNG works everywhere and is supported by every image viewer and browser.
Avoid PNG when: you need to print the code at a large size. A 300 px PNG printed at 10 cm will look pixelated. For print, use SVG instead.
SVG (Scalable Vector Graphics) describes the QR code as a set of mathematical shapes rather than pixels. This means it can be scaled to any size — from a 1 cm label to a 3 metre billboard — without any loss of quality.
Use SVG when: you are sending the code to a printer, placing it in a design application like Adobe Illustrator or Inkscape, or need the code to appear at a size larger than 5 cm. SVG is the professional standard for print-ready QR codes.
Note: SVG files require a vector-capable application to open. They will not display correctly in basic photo viewers, but work perfectly in browsers, Illustrator, Inkscape and most design tools.
STL (Standard Tessellation Language) is the standard file format for 3D printing. NoTraQR generates an STL file where the QR code modules are raised as a flat tile, ready to be loaded directly into slicing software.
Use STL when: you want to print a physical QR code plaque using a 3D printer. The modules are raised by 0.4–0.8 mm above the base tile. For a two-colour result, use a filament change at the layer where the modules begin, or use a multi-material system such as Bambu AMS.
Compatible slicers: Bambu Studio, Cura, PrusaSlicer, OrcaSlicer and any other slicer that accepts standard STL files.
Tip: Use error correction level H when generating an STL code. Physical prints are often subject to wear and the higher error correction ensures the code remains scannable even after handling.
