When to Convert PNG to JPG

  • Photos and natural images: JPG is ideal — 80% smaller file with nearly identical visual quality
  • Web uploads: Many sites (WordPress, Shopify, social media) prefer JPG for faster loading
  • Email attachments: JPG keeps your email under size limits
  • Bulk images: Converting a folder of PNGs to JPG can save gigabytes of storage

When to Keep PNG

  • Screenshots with text (JPG makes text blurry)
  • Graphics with sharp edges and flat colors
  • Images you will edit multiple times (no generation loss)

Quality Settings Explained

QualityBest ForTypical Size Reduction
95-100%Professional photography, print40-60% smaller than PNG
85-94%Web images, social media (recommended)70-85% smaller
70-84%Thumbnails, email attachments85-92% smaller
Below 70%Quick previews only90%+ smaller but visible artifacts

Pro tip: 85% quality is the sweet spot for most uses — the quality difference from 100% is invisible to the human eye, but the file is 3-5x smaller.

Handling PNG Transparency in JPG

The biggest gotcha when converting PNG to JPG: JPG does not support transparency. If your PNG has a transparent background, you need to decide what replaces it.

  • Default (white): Transparent areas become white — works for most documents and web use
  • Black background: Good for dark-themed designs
  • Custom color: Match your website or design background

For product photos with transparent backgrounds, choose white — it is the standard for e-commerce (Amazon, Flipkart, Shopify).

Common Use Cases

E-commerce Product Photos

Amazon, Flipkart, Shopify, and Etsy require or prefer JPG for product listings. Convert at 90% quality for best clarity and fast loading.

Website and Blog Images

Large PNG files slow down your website. Google PageSpeed Insights often flags PNGs that should be JPGs. Converting improves Core Web Vitals and SEO.

Social Media Posts

Instagram, Facebook, and Twitter compress uploads anyway. Pre-optimized JPG gives you more control over final quality.

Document Scanning

Scanned documents often save as PNG. Converting to JPG reduces size 5-10x for easier emailing and cloud storage.

Tips for the Best JPG Quality

  • Start with the highest quality source — converting a low-quality PNG will not improve it
  • Use 85-92% quality for web use — visually identical to 100%, dramatically smaller file
  • Do not convert JPG to PNG to JPG — each lossy conversion degrades quality
  • For text-heavy images: Use higher quality (92%+) to keep text crisp
  • For photos: 80-85% is usually enough — photos are more forgiving of compression
