A center logo works by obscuring part of the QR grid and relying on error correction to recover the missing information. It is a controlled compromise, not a guaranteed feature. Keep the mark modest, protect functional patterns, and test the final production object.

Start with the unbranded code

Finalize the payload and generate a plain code first. If that source does not scan consistently, a logo will not fix it. Shorten the payload where possible and choose a correction level appropriate for intentional obstruction - often Q or H as a testing starting point.

Higher correction can make the grid denser. Recalculate the physical size after changing it.

Prepare a safe logo file

Use PNG, JPEG, or WebP from a trusted source. HighEndDIY rejects SVG logo uploads because SVG can contain active or externally referenced content. It limits file size, decodes the raster locally, and re-renders it before use.

A simple mark with a clear silhouette usually works better than fine text. Put it on a solid patch that separates it from modules, but keep that patch small.

Protect the structure

Never cover the three finder squares. Avoid alignment patterns and retain the full quiet zone. Center placement often reduces the risk of touching structural features, but the exact symbol version determines where alignment patterns appear.

HighEndDIY limits the logo control to a conservative portion of the code. Treat its warning as a prompt to test, not as certification.

Original test sequence

A maker generates a short HTTPS code at Q correction and 40 millimeters wide. She tests the plain file, adds a 20-percent center mark, prints it on matte stock, and scans at several angles. She then tries 28 percent. Two older devices become inconsistent, so the final design returns to 20 percent rather than selecting the visually largest option.

Keep branding outside when possible

The safest logo may be the one placed beside the code. A clear heading, brand color in surrounding typography, and owned domain can establish identity without sacrificing modules. If the center mark adds little recognition, remove it.
