Image formats affect compatibility, transparency, visual detail and download size. There is no single best format for every image, so the right choice depends on what the file contains and where it will be used.
JPG
JPG is a common choice for photographs and complex colour gradients. Its compression can create small files, but repeated editing and saving may introduce visible artifacts. JPG does not support transparent backgrounds.
PNG
PNG preserves image data without lossy compression and supports transparency. It works well for logos, screenshots, diagrams and graphics containing sharp edges. Convert a photograph with the JPG to PNG tool when transparency or PNG compatibility is required, but remember that conversion cannot restore detail already removed by JPG compression.
WebP
WebP is designed for efficient delivery on modern websites and can support both lossy and lossless compression. The Image to WebP converter is useful when preparing supported JPG or PNG images for the web.
A simple selection rule
- Photograph: start with JPG or WebP.
- Transparent logo: use PNG or WebP.
- Screenshot or diagram: use PNG.
- Website performance: test WebP and compare the visible result.
