How to add a logo to a QR code.
A practical guide to choosing a logo, protecting QR patterns, and checking the finished image.
Start with a simple mark
A center logo is much smaller than a website header. Use a compact symbol with a clear silhouette. Tiny lettering, elaborate illustrations, and wide wordmarks can become hard to recognize. A transparent PNG is a useful choice; JPG and WebP also work.
Add it on the creation page
Open the QR code with logo tool, enter a stable website address, and upload your image. Dotlane accepts images up to 5 MB and up to 4,096 pixels on either side. The image is opened locally and normalized for the final code.
Give the code room to work
A logo covers some of the data area. Dotlane enables high error correction, limits the center badge, adds a clear border, and preserves reserved QR patterns. The logo may shrink or show an alignment pattern over part of the image. Error correction is not a promise that any size of logo will scan.
Check the personal result page
Choose Generate QR code to open your result. For logo codes, Dotlane rasterizes the complete image and checks that a local decoder reads the original content. Downloads stay disabled if it cannot confirm that match. Shorten long content or adjust the style if a result needs changes.
Test the file you actually share
Download PNG or SVG, then open that file and scan it on a phone. Try your actual printed sample at the expected size, distance, and lighting. Keep the margin intact. A successful digital scan check does not account for glare, printing errors, or every camera.
