PNG to JPG Conversion FAQ
How much smaller will my files become?
Typical file size reductions range from 70-90% depending on the original image. Photographs see the largest reductions, while simple graphics with few colors see moderate reductions.
Will I lose image quality during conversion?
JPG uses smart compression that maintains excellent visual quality while reducing file size. At 85-95% quality settings, the difference is virtually unnoticeable for most viewing purposes.
What happens to transparent backgrounds?
JPG format doesn't support transparency, so transparent areas will become white. If you need transparency, keep the original PNG or consider using the image on appropriate backgrounds.
