Choosing the right image format used to be simple: JPG for photos, PNG for everything else. Then WebP arrived and changed the math. Here is a practical comparison to help you pick correctly every time.
The quick comparison
| Feature | JPG | PNG | WebP |
|---|---|---|---|
| Best for | Photos | Graphics, text | Both |
| Transparency | No | Yes | Yes |
| Animation | No | No | Yes |
| Typical size | Baseline | Large | 25-35% smaller than JPG |
| Browser support | 100% | 100% | ~97% |
Use JPG when…
You need maximum compatibility — for example when emailing files to clients, using older software, or printing. Keep in mind that JPG does not support transparency and re-saving it repeatedly slowly degrades quality.
Use PNG when…
You need pixel-perfect lossless quality, sharp edges (text, logos, screenshots) or transparency — and file size does not matter much.
Use WebP when…
You are publishing images on a website — which is most of the time. You get JPG-like photo quality, PNG-like transparency, and files that are 25-35% smaller. For blogs, shops and portfolios, WebP is the clear default in 2026.
