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
