Frequently Asked Questions
Why convert JPG to PNG?
PNG is a lossless format, meaning no quality is lost during saving. It's 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 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.
Is my image uploaded to a server?
No. All conversion happens entirely in your browser. Your images never leave your device.
Can I convert multiple JPG files at once?
Yes. Select multiple JPEG files and they will all be converted. You can download them individually or use the "Download All" button for a ZIP archive.
