Place corporate logos inside the center of Qodex QR codes safely without breaking scannability.
Evaluate logo dimensions relative to grid error thresholds.
Logo area covers approximately 2.3% of cells, vs your selected 25% ECC.
Our tools align with international barcode specifications (ISO/IEC 18004:2015) and WCAG 2.1 digital luminance contrast compliance equations.
Custom brand integration is a core requirement for modern SMBs. The Qodex AI QR Code Generator SaaS allows logo inserts by utilizing Reed-Solomon Error Correction models to rebuild the covered modules. This tool computes logo area thresholds to prevent scan degradation.
QR codes support four Error Correction Levels (ECC): Level L (restores up to 7% damage), Level M (up to 15%), Level Q (up to 25%), and Level H (up to 30%). When placing a logo in the center, you must choose Level Q or Level H, and ensure the logo occupies less than that percentage of total cells.
Keep logos exactly centered. Avoid covering the three corner finder patterns (position detection blocks) or the smaller alignment patterns. Leaving a tiny margin of background color around the logo (quiet zone wrapper) prevents decoders from misinterpreting data borders.
We recommend Level H (High), which provides up to 30% error correction, allowing you to place a prominent center logo with complete security.
Yes, but ensure the transparent areas do not expose modules that conflict with the logo shape, as this can confuse the scanner.
