•Expecting the PNG file size to be smaller than WebP (PNG is a lossless format, so file sizes are typically larger than lossy WebP).
•Using shady cloud converters that upload your personal photos to third-party servers.
•Renaming the file extension manually from .webp to .png (this corrupts headers; proper format re-encoding is required).

•Opening web-downloaded WebP images in legacy desktop photo editors like Photoshop CS6.
•Extracting transparent product renders for e-commerce Shopify and Amazon stores.
