JPG
Universal Photo Standard
Great compatibility. No transparency. Ideal fallback for photo assets.
Format Strategy
Best Image Format for Websites
Use this decision framework to choose the best format per asset type, then apply conversion and compression with the right tool chain.
Match format to content, not habit.
Quick Decision Matrix
| Asset Type | Best Format | Fallback | Why |
|---|---|---|---|
| Photos / hero images | AVIF or WebP | JPG | Great compression with acceptable visual quality. |
| Logos with transparency | PNG or SVG | WebP | Sharp edges and transparency support. |
| UI icons / simple vectors | SVG | PNG | Resolution-independent and often smallest for vector shapes. |
| Animations | WebP (animated) | GIF | Better quality/size than GIF in most modern browsers. |
WebP
Balanced Modern Default
Strong compression and broad browser support. Good default for many websites.
AVIF
Best Compression Potential
Often smallest output at similar quality, but encode/decode can be slower in some workflows.
Recommended Workflow
-
Step 1
Convert source images with Image Format Converter.
-
Step 2
Choose AVIF/WebP for primary assets and keep JPG fallback for compatibility-critical contexts.
-
Step 3
Run outputs through Image Compressor to reduce transfer size.
-
Step 4
Audit your library periodically to replace oversized legacy PNG/JPG files where practical.
Frequently Asked Questions
-
Usually for size, yes, but compatibility and workflow constraints still matter in some environments.
-
Not always. Flat graphics, logos, and assets needing strict transparency behavior may remain better in PNG or SVG.
-
Use AVIF for photo-heavy pages where maximum compression is the priority and decode performance is acceptable.
-
Start with WebP as a safe modern default, then test AVIF on high-traffic image sets for additional gains.
