Use JPG for photos you share, PNG for logos, screenshots and graphics that need sharp edges or transparency, and WebP for almost every image on a website. WebP combines small file sizes with support for transparency and is supported by all major modern browsers. Here is a clear comparison and a simple decision rule.
- Photo for sharing or forms: JPG.
- Logo, icon, screenshot, transparent graphic: PNG (or WebP).
- Any image on your website: WebP.

JPG: the universal photo format
JPG uses lossy compression that discards detail the eye barely notices, giving small files for photos. Every device and app opens it. Downsides: no transparency, and repeated editing and saving gradually reduces quality.
PNG: crisp graphics and transparency
PNG is lossless, so text, lines and flat colours stay perfectly sharp, and it supports transparent backgrounds. That makes it ideal for logos, icons and screenshots, but photos saved as PNG are much larger than JPG.
WebP: the modern web format
Developed by Google, WebP supports both lossy and lossless compression, transparency and animation. Google reports lossy WebP files are typically 25 to 34% smaller than comparable JPGs. WordPress and all major browsers support it, making it the best default for website images.
