How much can images be compressed?

Typical JPEG compression at 80% quality reduces file size by 60–80% with minimal visible quality loss. PNG files with many colors compress less than simple graphics.

Does image compression use a server?

No. The browser Canvas API compresses images locally. Nothing is uploaded.

Will the image quality be noticeably reduced?

At 80% quality, most people cannot distinguish compressed from original images. At 60% quality, some compression artifacts become visible in complex areas.
