FAQ

What information is lost in lossy compression?

Lossy compression loses some image details and color information. Lower quality means more loss. Extreme compression may show obvious block artifacts.

Can compressed images still be viewed?

It is recommended to keep compression quality above 30%, when images are still recognizable with some detail loss.

why choose JPG format?

JPG format supports lossy compression and compresses much better than PNG, making it the top choice for high compression rates.
