Frequently Asked Questions

Will converting a JPG to PNG improve its original image quality?

Converting from JPG to PNG cannot restore lost details or remove existing JPEG compression artifacts, but it freezes the current quality so subsequent edits do not suffer further generational compression loss.

Does converting JPG to PNG make the background transparent?

No, standard JPGs do not contain alpha channel metadata. Converting to PNG produces an opaque PNG. To create transparency, you can use our crop, color-picker, or eraser tools.

What color depths are supported in the output PNG?

The output is encoded as standard 24-bit RGB (with 8 bits per channel) or 32-bit RGBA, fully conforming to ISO/IEC 15948 PNG standards.
