Will converting a JPG to PNG improve its image quality?

Converting to PNG cannot restore detail already lost to JPG compression, but it prevents any further quality loss during future edits and saves.

Will the resulting PNG have a transparent background?

Standard JPGs do not support transparency and have solid backgrounds. Converting to PNG allows you to open and edit the image in graphic software to add transparency.

Are my JPG files uploaded to an external server?

No. Conversion runs locally in your browser memory. Your images never leave your device, ensuring total privacy.

Why is the converted PNG file larger than the original JPG?

PNG is a lossless format that retains every pixel without compression discard, resulting in larger file sizes that preserve maximum visual detail.
