Frequently asked questions
Does converting JPG to PNG restore lost quality?
No — details already lost to JPG compression cannot be recovered. PNG preserves the current pixels exactly, without adding new loss.
Why is the PNG file bigger?
PNG uses lossless compression, which is larger for photos. It is the right choice when quality must not degrade further, not for shrinking files.
Are my images uploaded?
No. Conversion happens entirely in your browser on your own device.
