Frequently Asked Questions

Why convert JPG to PNG?

PNG is needed when you require lossless quality (no compression artifacts), transparency support, or when editing images that will be re-saved multiple times (each JPEG save degrades quality further).

Does JPG to PNG conversion improve quality?

No — you cannot recover quality lost during JPEG compression. However, converting to PNG prevents further quality degradation from re-compression. The converted PNG will be the same quality as the JPEG source.

Will the PNG file be larger than the JPG?

Yes — PNG files are typically 3-5× larger than equivalent JPEGs because PNG uses lossless compression. Only convert to PNG when you specifically need lossless format or transparency.

Can I add transparency after converting JPG to PNG?

The converted PNG will have a solid background (JPG doesn't support transparency). To add transparency, you'll need to remove the background using a photo editor or background removal tool after converting.

Can I batch convert JPG to PNG?

Yes — upload multiple JPEG files and all will be converted to PNG simultaneously in your browser.
