How it works
Modern image converters usually let users switch between common web formats like JPG, PNG, and WebP directly in the browser, with preview, download, and privacy-preserving local processing. Many also provide quality controls for lossy formats and preserve transparency only when the target format supports it.
- JPG is commonly used for photos and smaller lossy exports.
- PNG is commonly used when lossless quality or transparency matters.
- WebP is commonly used for smaller web-friendly output with broad modern browser support.
