WebP vs JPG vs PNG: Which Should You Use?
Last updated: 2026-06-25 · By the ImageTools editorial team
Photos: JPG or WebP. Transparency, logos and screenshots: PNG or WebP. Website speed optimization: WebP is the answer.
WebP is about 25–35% smaller than JPG at the same quality, but when compatibility with older programs matters, JPG and PNG are safer.
The core differences
Image formats differ in their compression method and supported features. Compression splits into lossy (discards data to shrink the file) and lossless (keeps the data exactly). Lossy is small but slightly lower quality; lossless is perfect quality but larger.
| Aspect | JPG | PNG | WebP |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy & lossless |
| Transparency | No | Yes | Yes |
| Animation | No | No | Yes |
| Size at same quality | Medium | Large | Smallest |
| Compatibility | Very high | Very high | High (modern environments) |
| Typical use | Photos | Logos & icons | Web images |
JPG — the photo standard
JPG (JPEG) has been the most universal photo format since 1992. Its lossy compression packs colorful photos into small files, and it opens on virtually every device, program and service. The downsides: it does not support transparency, and saving the same image repeatedly accumulates a little quality loss each time.
JPG is good for: regular photos, sharing on social and messaging apps, and when you need the broadest possible compatibility.
PNG — king of transparency and sharpness
PNG uses lossless compression, so quality is never degraded. It supports a transparent background (alpha channel), making it essential for logos, icons and UI elements, and it keeps text-heavy screenshots crisp. The downside is that for colorful photos the file gets very large.
PNG is good for: images that need a transparent background, logos and icons, text-heavy screenshots, and lossless archival originals.
WebP — the most efficient modern format
WebP is a modern format from Google that supports both lossy and lossless compression and handles transparency and even animation. Its biggest advantage is efficiency: at the same quality it is about 25–35% smaller than JPG, and in lossless mode about 20–30% smaller than PNG. That is why it is so widely used for website loading-speed optimization.
As of 2026, Chrome, Edge, Safari, Firefox and the default viewers on Windows and macOS all support WebP. That said, very old software may not open it, so for general sharing JPG can still be the safer choice.
WebP is good for: website and blog images, when you want the smallest possible file, and when you want transparency and small size together.
Situation-by-situation recommendations
| Situation | First choice | Alternative |
|---|---|---|
| Sharing regular photos | JPG | WebP |
| Website images | WebP | JPG |
| Transparent logo | PNG | WebP |
| Screenshot (lots of text) | PNG | WebP (lossless) |
| Maximum compatibility | JPG | PNG |
| Minimize file size | WebP | JPG |

Frequently asked questions (FAQ)
Which is better, WebP or JPG?
On size alone, WebP is about 25–35% smaller than JPG at the same quality, so it is more efficient. But if compatibility with older programs matters, JPG is safer. WebP for websites, JPG for general sharing is a solid rule of thumb.
Which format should I use if I need a transparent background?
Use PNG or WebP. JPG does not support transparency, so transparent areas get filled with white.
Which format is best for screenshots?
Screenshots full of text and lines look sharpest as PNG. For mostly-photographic screens, JPG or WebP is fine too.
Is WebP worse in quality?
No. WebP often looks better than JPG at the same file size, because its compression algorithm is more modern.
