图片压缩器

How image compression works

Compvert compresses JPEG images using progressive encoding and intelligent quality optimization, typically achieving 60–90% size reduction. PNG files are optimized with lossless algorithms, preserving transparency and every pixel perfectly. WebP images use advanced compression achieving 25–35% smaller sizes than JPEG at equal quality.

The quality slider lets you control the trade-off between file size and visual quality. For most use cases, 80% quality produces excellent results that are indistinguishable from the original at much smaller file sizes. EXIF metadata (GPS location, camera settings) is stripped by default to further reduce size and protect your privacy.
