WebP vs JPEG vs PNG: Which Image Format to Use in 2026
WebP is 25-35% smaller than JPEG at the same quality. PNG is lossless but 3-5× larger. Full comparison with browser support, quality tradeoffs, and when each wins.
The short answer
Use WebP for photos on the web, with JPEG as a fallback for ancient browsers (now <1% of traffic). Use PNG (or WebP lossless) for screenshots and images with text. Use SVG for logos and icons. Use JPEG only when your pipeline can't produce WebP.
Size at identical perceived quality
| Format | 4000×3000 photo | Logo PNG | Screenshot (text) |
|---|---|---|---|
| JPEG q=85 | ~480 KB | — | ~180 KB (text fuzzy) |
| WebP q=85 lossy | ~310 KB | — | ~115 KB (text fuzzy) |
| PNG | ~15 MB (impractical) | 24 KB | 340 KB (text crisp) |
| WebP lossless | ~9 MB (impractical) | 18 KB | 240 KB (text crisp) |
Lossy vs lossless in one line
Lossy discards information your eye won't easily notice — 3-10× size savings, some quality loss. Lossless keeps every pixel exact — modest savings via smarter encoding. JPEG is lossy-only; PNG is lossless-only; WebP does both.
Browser support (2026)
- WebP — 98.2% global (Safari 14+, Edge, Chrome, Firefox)
- AVIF — 93% global (smaller than WebP but slower to encode; still worth using for high-traffic pages)
- JPEG, PNG, GIF — 100% everywhere since forever
When format actually matters
- SEO / LCP — Google rewards fast image loads. WebP shaves 25-35% off JPEG-quality photos, which can lift LCP by hundreds of ms.
- Mobile data — every byte counts on 3G. Smaller images = more page views before the user hits their data cap.
- Print — use JPEG (universal) or PNG (for logos). WebP support in print software is inconsistent.
- Email — embed as PNG or JPEG. Some clients (Outlook) don't render WebP.
What about AVIF?
AVIF is generally 20% smaller than WebP at the same quality. Support is at 93% and climbing. Use <picture> with AVIF first, WebP fallback, JPEG final fallback. For single-format workflows (CMS uploads), WebP is still the right default — simpler tooling, broader support.
Converting existing images
To reduce file size without changing format, use image compressor — it also supports output to WebP and handles the lossy/lossless toggle. For resizing dimensions before publishing, image resizer. Optimizing SVG logos is a different workflow — use SVG optimizer.
One rule of thumb
Convert every photo to WebP. Keep PNG for screenshots with text. Use SVG for anything that started as vector. If you do only that, your page weight typically drops 40-60%.
