WebP vs AVIF — which should I use?

AVIF produces smaller files (10-20% smaller than WebP) but has slower encoding and less broad support (Safari < 16.4). WebP is universally supported in modern browsers and has fast encoding. Use AVIF with a WebP fallback for best results, or WebP alone for simplicity.

What quality level should I choose?

For photographs: 80-85 quality is visually lossless and significantly smaller than 100. For graphics with text or sharp edges: use PNG (lossless) or WebP at 90+ quality. Always compare the compressed result visually — quality numbers are not comparable across formats.

Komprimieren and optimize images for the web

Reduzieren image Datei Größe durch converting formatieren (WebP/AVIF), adjusting quality, und resizing für faster Seite loads.

Images are the largest payload on most web pages. Converting to modern formats (WebP, AVIF) and adjusting quality/size can cut bytes by 50-80% with minimal perceptual quality loss, directly improving Core Web Vitals.

Bild-Kompressor →
Upload an image. Choose target format (WebP for broad support, AVIF for smallest size), quality (80-85 for photos, 90+ for graphics with text), and optionally resize. The tool outputs the compressed file with before/after size.
