JPG to PNG — when to convert
Convert JPG to PNG when you need a transparent background (PNG supports transparency, JPG does not) or when you need to edit the image further without quality loss. PNG is lossless — editing and re-saving does not reduce quality.
PNG to JPG — when to convert
Convert PNG to JPG when file size matters and you don't need transparency. JPG files are typically 60–80% smaller than equivalent PNGs for photographic content.
JPG to WebP — why bother
WebP is Google's modern image format. For web use, WebP is 25–35% smaller than JPG at equivalent visual quality. If you're uploading images to a website, converting to WebP before upload improves page speed and Core Web Vitals scores.
