Frequently Asked Questions

Why convert JPG to PNG?

PNG is a lossless format, meaning no quality is lost during saving. It is ideal for images with text, sharp edges, or when you need to edit and re-save without quality degradation.

Will the PNG be larger than the JPG?

Yes, typically PNG files are larger than JPEG because PNG uses lossless compression. The trade-off is perfect quality for a larger file size.

Does PNG support transparency?

Yes, PNG supports alpha transparency. However, since the source is JPEG (which has no transparency), the resulting PNG will have a fully opaque background.

Can I convert multiple JPG files at once?

Yes. Select multiple JPEG files and they will all be converted. Download them individually or use Download All to get a ZIP archive.

Is my image uploaded to a server?

No. All conversion happens entirely in your browser. Your images never leave your device.

Which file types can I convert?

This tool accepts JPEG files (.jpg and .jpeg). Other file types are filtered out when you select your images.
