Improve scanning by using suitable contrast, size and clear space around the code.
When this guide is useful
A QR code needs good contrast and a clear margin around it so different cameras can recognize it easily.
Think about where the file will be used. Messaging, social media, websites, presentations and archiving can require different sizes and formats.
How to decide without overcomplicating it
Test the code on more than one device before printing or publishing it. For printed material, test at the real final size.
Always start with a copy of the original file. That gives you a reference and lets you try another setting without losing the best-quality source.
How to check whether the result is good
Make a first attempt with moderate settings. Then review the full result, especially areas with small text, faces, music, transitions or fine detail.
