Quality vs File Size

For a typical 2MB photo:

100% quality: ~2MB (no reduction)
90% quality: ~500KB (75% reduction)
80% quality: ~200KB (90% reduction)
70% quality: ~120KB (94% reduction)

Best Practices

1. Use WebP when browser support allows 2. Resize first: Don't compress a 4000px image for a 400px display 3. Consider lazy loading: Only load images when visible 4. Use srcset: Serve appropriate sizes for different screens

Frequently Asked Questions

How does image compression work?

This compressor uses the Canvas API to re-encode images at a specified quality level. For JPEG/WebP, lowering quality increases compression. PNG compression is lossless but can reduce file size by optimizing encoding.

Is the compression lossy or lossless?

JPEG and WebP compression is lossy—some image data is discarded. PNG compression is lossless. The quality slider controls how much data to discard for JPEG/WebP; lower values mean smaller files but more quality loss.

What quality setting should I use?

For photos on web: 70-80% quality is usually optimal (good balance). For thumbnails: 60-70% is fine. For high-quality images: 85-90%. Below 60%, compression artifacts become noticeable.
