Image Conversion Tips & Best Practices

Use WebP for web images — 25-35% smaller than PNG/JPEG with comparable quality

Use PNG for images requiring transparency (logos, icons, UI overlays)

Use JPEG for photographs — best compression-to-quality ratio for photo content

Do not rename raster files as SVG — true vector export needs a vector source

Check the transparency warning before converting PNG to JPEG — transparent pixels become white

Use ICO format for website favicons — most browsers expect this format
