Which format should I pick?
Unsure? Pick WebP: small, transparent, opens everywhere. JPG for people on old software; PNG for re-editing or transparent backgrounds; AVIF for the smallest possible files (slower than WebP); BMP only when legacy software explicitly demands it; ICO for website icons and Windows shortcuts (packs 16 / 32 / 48 / 256 in one export, image center-cropped square). iPhone HEIC originals convert directly to jpg / png / webp.
The white-background handling for JPG & BMP
JPG and BMP have no transparency — naive converters turn transparent areas black. This tool lays a white background first, so transparency becomes white correctly — the most common gotcha converting screenshots to JPG.
