Tips

WebP — best choice for the web, smallest size with good quality.
JPEG — widely supported, good for photos, but no transparency.
PNG (Lossless) — original quality preserved, bigger files, supports transparency.
PNG (WebP encoded) — compresses like WebP but saved with a .png extension. Smaller, but not a true PNG.
PNG (Palette via UPNG.js) — reduces colors (2–256) for big size savings, good for graphics/icons.
Lower the quality slider to get smaller files; watch visual differences.
