Frequently Asked Questions

What is the difference between JPG and PNG?

JPG uses lossy compression (smaller files but some quality loss), while PNG uses lossless compression (larger files but perfect quality). PNG also supports transparency; JPG does not.

Does converting JPG to PNG improve quality?

Converting won't restore quality already lost in the JPG. However, PNG prevents further quality loss from repeated saves, making it better for editing workflows.

Will the PNG file be larger than the JPG?

Yes, typically. PNG files are larger because they use lossless compression. For photos, JPG is more efficient. For graphics with text or logos, PNG is better despite the larger size.
