Convert JPG, PNG, WebP Images & Compress
JPG suits regular photos. PNG suits logos or images that need a transparent background. WebP files are about 25-35% smaller than JPG at similar quality, ideal for website images.
80-85% is the sweet spot where files get much smaller with almost no visible difference. For product photos that need to be very sharp, use 90%.
PNG is lossless, so photos converted to PNG are often several times larger than JPG. Use PNG only when you need transparency or for flat-color graphics.
Full-width images shouldn't be wider than 1600-2048px or larger than 200-300 KB. For images in articles, 1080-1200px is enough.
All free, and files are never uploaded to a server
