Why Convert PNG to JPEG
Web and social media optimization
JPEG files load faster and save visitor bandwidth. Social networks and messengers work better with JPEG: images aren't re-compressed and maintain quality when shared.
When to keep PNG as is
Don't convert logos, icons, diagrams, or any graphics with text or sharp lines to JPEG. JPEG compression creates artifacts around high-contrast edges that are especially noticeable in such images.
Quality selection tip
Start with quality 85 — this is the optimal balance between file size and visual quality. If the result looks blurry, increase to 90-95. For email newsletters and previews, you can safely go down to 70.
