Why Change a PNG Photo to JPG?
JPG is often more practical for photographs because it can produce smaller files than PNG. This can help with email attachments, web uploads and storage limits.
Reduce Large PNG Photo Files
Screenshots and exported photos saved as PNG can be much larger than necessary. Converting photographic PNG files to JPG can reduce file size while keeping the image easy to view and share.
When You Should Keep PNG Instead
Keep PNG when you need transparency, lossless graphics, logos, interface images or screenshots with very sharp text. JPG is usually better suited to photographs.
Transparent PNG Backgrounds
JPG cannot store transparent pixels. A transparent PNG therefore needs a solid background when it becomes a JPG, so check the result before using it in a design or website.
