PNG vs JPEG vs WebP: When to Use Each Format (2026)
The most common question I get: "Which format should I use?"
Here's the definitive answer.
Quick Answer
| Image Type | Best Format |
|---|---|
| Photos for web | WebP (JPEG fallback) |
| Graphics with text | PNG or SVG |
| Screenshots | PNG or WebP |
| Logos/icons | SVG |
| Transparency needed | WebP or PNG |
The Short Version
Use WebP for everything web.
It's 30-50% smaller than JPEG, supports transparency, and has 97%+ browser support.
JPEG is still fine as a fallback.
PNG is for when WebP won't work (transparency + broad compatibility).

Real Examples
Example 1: Product Photo
Image: 2000x2000 product photo Goal: Display on website at 800x800
Wrong: Upload 2000x2000 PNG Result: 4.2 MB, slow loading
Right: Resize to 800x800, save as WebP Result: 45 KB, fast loading
Example 2: Screenshot
Image: Application screenshot with UI text Goal: Display in documentation
Wrong: Save as JPEG Result: Blurry text
Right: Save as PNG Result: Sharp text, 280 KB
Better: Convert to WebP Result: Sharp text, 95 KB
Example 3: Logo
Image: Company logo with transparent background Goal: Display on various backgrounds
Wrong: Save as JPEG Result: White box around logo
Right: Save as SVG (best) or PNG with transparency Result: Transparent background, perfect on any color

FAQ
Q: Can I use WebP for everything?
A: Yes, for web. It's smaller and quality is equal to JPEG.

<picture>
<source srcset="image.webp" type="image/webp">
<img src="image.jpg" alt="Description">
</picture>
Q: When is PNG better than WebP?
A: When you need lossless quality AND transparency, and WebP lossy isn't good enough.

A: Yes. Re-save as WebP - typically 30-50% smaller.
