JPG to PNG Converter – Convert JPG to PNG Online

PNG uses lossless encoding and supports transparency. Converting an existing JPEG does not restore detail already lost during JPEG compression.

Often yes. PNG encoding is lossless, but file size depends on image content and the original JPEG. Use the image compressor afterward if file size matters.

No — JPG files don't have transparency to begin with, so the PNG output keeps the same solid background as the original JPG. To get a transparent background, you'd need to remove it in an editor after conversion.

PNG is best for screenshots, logos, icons, and graphics with text or hard edges. JPG is better for photographs. If you need both small size and transparency, consider WebP.
