Use JPG for photographs and broad compatibility
JPG is widely supported and works well for photographs where small color changes are less noticeable. It uses lossy compression, so saving the same image repeatedly can gradually reduce quality.
JPG does not support transparency, which matters for logos, cut-out product images and overlays.
Use PNG for transparency and crisp graphics
PNG uses lossless compression and supports transparent pixels. It is a strong choice for screenshots, interface graphics, diagrams and logos with sharp edges.
Photographs saved as PNG can be much larger than equivalent JPG or WebP files, so PNG is not always the most efficient choice for a website.
Use WebP for modern web delivery
WebP is supported by modern browsers and can provide efficient compression for both photographic and graphic content. It can also support transparency.
When compatibility with older software matters more than file size, JPG or PNG may still be easier. Usefulia provides direct browser-based conversions between these common formats.
