# PNG to JPG Converter — Convert PNG to JPG Online Free

Convert PNG images to JPG for smaller files that open everywhere, with quality control and white backgrounds for transparency. Free and in your browser.

Updated July 2026 · Reviewed by the PDFWix Team (https://www.pdfwix.com/about/team)

PNG is perfect for screenshots and graphics, but photos saved as PNG are often five to ten times larger than they need to be, and many upload forms only accept JPG. Converting PNG to JPG shrinks those files dramatically and makes them universally accepted. PDFWix converts PNG to JPG in your browser with adjustable quality and fills any transparent areas with clean white.

To convert PNG to JPG free: open PDFWix PNG to JPG, add your .png files, choose a quality (92% default), click Convert to JPG and download the smaller files.

## When PNG to JPG makes sense — and when it doesn't

PNG stores every pixel losslessly, which is ideal for text, UI screenshots, diagrams and logos but wasteful for photographs full of subtle colour variation. JPG's lossy compression was designed for exactly those photos, so converting a photographic PNG to JPG usually cuts its size by 70–90% with no visible change. Keep PNG when the image has a transparent background you need, or when it contains small text and sharp edges that JPG would soften. For those cases, Compress Image (https://www.pdfwix.com/compress-image) can shrink it as WebP while keeping transparency.
