Compress WebP Images

Many tools convert JPG→WebP at 90-100% quality, preserving JPG's bloat. A 2MB JPG at 95% becomes 1.5MB WebP at 95%—format advantage only. Same JPG → WebP at 80% becomes 600KB—format + compression advantage. Check source WebP quality: if 85%+, recompress to 80% for 30-50% additional savings with minimal visual impact.

80-85% for photos and product images—imperceptible quality loss, 40-60% size reduction. 90% for portfolios or high-quality showcases. 75% for thumbnails or backgrounds. WebP at 80% quality typically looks better than JPG at 85% while being smaller. Test on actual content—gradients and textures compress differently than flat graphics.

Yes. WebP uses lossy compression—each recompression pass adds artifacts and compounds quality loss. Recompressing 90% WebP to 80% is acceptable. Recompressing 80% to 70% degrades noticeably. Always compress from highest quality source (original photo/graphic) when possible. Avoid compress → re-compress chains.

WebP uses VP8 video codec for compression vs JPG's DCT. WebP achieves 25-35% smaller files at equivalent visual quality. WebP at 80% ≈ JPG at 85% visually but 30% smaller file. WebP handles gradients better (less banding), sharp edges better (fewer artifacts), and supports transparency (alpha channel). Trade-off: 4% browsers lack support (IE11, old Safari).

Lossy for photos and realistic images—40-70% smaller than lossless with imperceptible quality loss at 80%+. Lossless for graphics, logos, screenshots—maintains pixel-perfect quality like PNG but 25-35% smaller. This tool applies lossy compression. For lossless WebP, export directly from design tools or use specialized converters.

Yes but artifacts more visible around edges. Compress transparent WebP at 85%+ quality to minimize alpha edge artifacts. Below 80%, semi-transparent areas may show compression banding. Test on actual backgrounds (light and dark) before deploying. For pixel-perfect transparency, use lossless WebP or PNG instead.
