Format Recommendations by Use Case

🌐 Website Images

Use AVIF with WebP and JPG fallbacks. The picture element serves the best format each browser supports. This gives you maximum compression for modern browsers while maintaining compatibility.

<picture>
  <source srcset="img.avif" type="image/avif">
  <source srcset="img.webp" type="image/webp">
  <img src="img.jpg" alt="...">
</picture>

📧 Email

Use JPG. Many email clients (Outlook, older Gmail) do not support WebP or AVIF. JPG has universal email client support.

📱 Social Media

Use JPG or PNG as specified by each platform. Most platforms re-encode uploads anyway. Check each platform's current requirements.

🖨️ Print

Use PNG or TIFF for lossless quality. Avoid JPG for print-critical work due to compression artifacts.

🎨 Icons & Logos

Use SVG for vector graphics. For raster icons, use PNG with transparency or WebP for smaller files.

Frequently Asked Questions

Which image format has the best browser support?

JPG and PNG have near-universal support (99.9%). They work in every browser and device. For maximum compatibility, use JPG for photographs and PNG for graphics with transparency.

Is WebP supported in all browsers?

WebP is supported by 97.5% of browsers as of 2026. All modern versions of Chrome, Firefox, Safari, and Edge support WebP. Only very old browsers lack support.

Should I use AVIF or WebP?

AVIF produces smaller files than WebP (about 20-30% smaller) but has slightly less browser support (92% vs 97%). For maximum compatibility, use WebP with JPG fallback. For maximum compression, use AVIF with WebP fallback.

How do I serve modern image formats with fallbacks?

Use the HTML picture element: <picture><source srcset='image.avif' type='image/avif'><source srcset='image.webp' type='image/webp'><img src='image.jpg' alt='...'></picture>. Browsers pick the first format they support.

Why is HEIC not supported in browsers?

HEIC uses Apple's HEVC codec which requires licensing fees. Browser vendors have chosen to support royalty-free alternatives like AVIF and WebP instead. Convert HEIC to JPG or WebP for web use.
