PNG vs JPG: What's the Difference?
Understanding the difference helps you pick the right format every time:
| Feature | PNG | JPG (JPEG) |
|---|---|---|
| Compression | Lossless — no quality loss | Lossy — small quality reduction |
| File Size | Larger (2-10x bigger) | Much smaller |
| Transparency | Supports alpha channel | No transparency |
| Best For | Logos, screenshots, graphics with text | Photos, web images, thumbnails |
| Color Depth | Up to 48-bit | 24-bit (16.7M colors) |
| Web Performance | Slower loading (larger) | Faster loading (smaller) |
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
- Logos and icons that need transparency
- 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
| Quality | Best For | Typical Size Reduction |
|---|---|---|
| 95-100% | Professional photography, print | 40-60% smaller than PNG |
| 85-94% | Web images, social media (recommended) | 70-85% smaller |
| 70-84% | Thumbnails, email attachments | 85-92% smaller |
| Below 70% | Quick previews only | 90%+ 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
