Convert PNG to JPG
The go-to lossless image format, with real transparency, so nothing is thrown away and edges over a background stay clean. Great for logos, screenshots and artwork. Lolly tags it with an sRGB profile, can boost it to genuine HDR brightness on capable screens, and embeds provenance and Content Credentials.
The classic photo format: smaller files by discarding detail your eye barely notices, which makes it ideal for photographs but poor for crisp graphics or text. It's always opaque (no transparency). Lolly tags it sRGB, can write an HDR version for bright displays, and embeds provenance and Content Credentials.
