FAQ
Does converting JPG to PNG improve existing image quality?
It does not retroactively add detail, but PNG preserves current pixels losslessly, preventing further compression artifacts during future editing.
Does the converted PNG have transparent backgrounds?
Because original JPG files lack an alpha transparency channel, the converted PNG will retain the original solid background colors.
Are my private photos uploaded to remote servers?
No. The conversion executes entirely in your browser using client-side Canvas APIs, keeping your visual assets private.
