Common conversions
Converting a transparent PNG to JPG flattens transparency onto a background colour you choose. Animated GIFs are flattened to their first frame.
Picking an output format
WebP is the safest modern default: it supports transparency and animation, is supported by every current browser, and is typically 25–35% smaller than JPEG at matched quality.
AVIF compresses better still, especially for photographic content. Browsers can't save AVIF on their own, so ImageDoctor encodes it with a built-in AVIF encoder, which is slower than WebP but works everywhere.
JPEG has no transparency. Converting a PNG with transparent areas to JPEG flattens them onto a background colour, which you can set before converting.
