Frequently Asked Questions
Q: Why convert JPG to PNG before editing?
Every time you edit and save a JPG image, it re-compresses and degrades quality. Converting to PNG stops generation loss and allows you to add transparent cutouts and layers.
Q: Can I batch convert multiple JPG files at once?
Yes! Upload multiple JPG images simultaneously and download all converted PNGs in a single ZIP package.
