What to know before using it

JPEG has no alpha channel, PNG can be large for photos, and WebP/AVIF trade compatibility for efficiency. Choose based on photo/graphics, transparency and target support.

Common failure points

Transparent PNG to JPEG requires a background color.
Converting a lossy JPEG to PNG cannot restore lost detail.
AVIF output depends on browser or bundled WASM support.

Practical example

Use WebP/AVIF for many photos, PNG/WebP for transparent graphics, and JPEG/PNG when broad compatibility matters most.
