Which format should I use?
JPG works almost everywhere and is ideal for photographs. PNG is useful for graphics, screenshots, and transparency. WebP can provide smaller files while keeping strong image quality. AVIF can be even smaller in browsers that support AVIF export. GIF and BMP can be opened as source images in modern browsers; animated GIFs convert as a still frame.
What happens to transparency?
PNG and WebP can preserve transparent areas. JPG cannot; transparent pixels are placed on a white background during JPG conversion.
Format problems solved
Switch image formats without changing dimensions.
Convert between JPG, PNG, and WebP when a site or workflow accepts one image format but not another.
PNG
Useful for graphics, screenshots, and images that need transparency. PNG output is lossless.
WebP
A modern web-friendly format that can reduce file size while maintaining strong visual quality.
What happens to transparency?
PNG and WebP can preserve transparent areas. If you convert a transparent image to JPG, the transparent area must become a solid background because JPG does not support transparency.
