Compare AVIF, WebP and PNG based on perceptual quality
The practical problem
Compression ratio is only useful if the game logo, thin UI text and illustration gradients survive at acceptable quality.
Implementation protocol
Export the same crop using a controlled encoder and several quality settings, evaluate at 100% and 200% view and measure decoded performance on a low-end mobile device.
Worked scenario
A 55 KB file with unreadable white lettering is less useful than a 75 KB file whose character and label remain sharp; inspect important semantic details.
What could go wrong
Comparing different crop dimensions can misattribute savings to a codec.
Acceptance criteria
Keep dimensions identical and include browser support in the release decision.
