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.
