JPG vs PNG vs WebP: Which Image Format Should You Use?

JPG is designed for continuous-tone images such as portraits, travel photos and product photography. It can make these files compact, but it discards detail and does not support transparent pixels.

Avoid JPG for logos, diagrams and screenshots with small text. Compression noise is most visible around hard edges, and a solid background will replace any transparency.

PNG is dependable for interface screenshots, logos and artwork with flat colors. Its lossless encoding preserves exact edges and its alpha channel supports partial transparency.

The tradeoff is size: a large photographic PNG can be many times heavier than an equivalent JPG or WebP. Use it because the image needs its strengths, not because PNG always sounds higher quality.

WebP can encode photographs with lossy compression and graphics with transparency. It is a strong default for web assets when your publishing workflow accepts it.

Keep an editable master in the original format. WebP should normally be treated as a delivery copy so future crops and exports do not start from an already compressed asset.

Choose JPG for a photo without transparency, PNG for crisp graphics or screenshots that require exact pixels, and WebP when a compact modern web copy is wanted. Then compare the actual outputs—image content determines the final size.

Also confirm what the destination accepts. Email clients, print vendors, social platforms and older content systems may have different format rules from a modern browser.
