About JPG and PNG
JPEG is a lossy photo format. PNG is lossless and useful in editing workflows. A PNG made from a JPEG may be larger and will not regain lost detail or gain a transparent background.
Frequently asked questions
Does converting JPG to PNG improve image quality?
No. PNG preserves the decoded pixels, but cannot restore detail already lost in the source image.
What happens to transparency in PNG?
PNG and WebP can keep transparent pixels when the source has them. Converting an opaque JPEG does not create transparency.
