How Does This Work?

JPEG compression works by reducing redundant image data. The quality slider controls how aggressively the image is compressed. At 75%, most photos look identical to the original while being significantly smaller.

Frequently Asked Questions

What quality should I use?

For web use, 70-80% is ideal. For email, 60-70% works well. For archival quality, use 90-100%.

Can I compress JPEG without losing quality?

JPEG is inherently a lossy format. However, at 90-95% quality, the differences are imperceptible to the human eye.
