WebP vs JPEG vs PNG: Which Image Format Should You Use?
The best format depends on the image, the transparency requirement and the systems that consume it. Format choice should follow the content and compatibility needs, not a single rule for every asset.

JPEG for photographs and broad compatibility
JPEG remains useful for photographs and email attachments. It supports adjustable lossy compression and is accepted nearly everywhere, but it does not support transparency and can introduce visible artifacts around text and sharp edges.
PNG for transparency and precise graphics
PNG is lossless and supports alpha transparency, making it suitable for logos, interface graphics and screenshots. Photographic PNG files can be very large, so converting those images to JPEG or WebP often produces a substantial reduction.
WebP for modern web delivery
WebP supports lossy and lossless compression as well as transparency. It commonly reduces web asset size while retaining comparable visual quality. Modern browsers support it widely, although some older editing or business workflows may still expect JPEG or PNG.
A practical decision process
Use JPEG when maximum interoperability matters, PNG when lossless detail or transparency is essential, and WebP for optimized website delivery when your workflow supports it. Always compare the real output because image content affects compression results.
