Format comparison
PNG vs WebP – modern format comparison for web
WebP is Google's modern image format, designed to replace both PNG and JPG with smaller files. But PNG remains the more universal choice. Here is a practical breakdown of when each format makes sense.
Side-by-side comparison
| Feature | PNG | WebP |
|---|---|---|
| Transparency | ✓ Supported | ✓ Supported |
| Compression | Lossless only | Lossless + Lossy |
| File size | Larger | 25–35% smaller |
| Browser support | Universal | Modern browsers only |
| Design tool support | Universal | Limited |
| Animation | No (use GIF/APNG) | ✓ Supported |
| Best for | Editing, design, assets | Web delivery, performance |
When PNG wins
- Design workflows. Figma, Photoshop, Canva, and most design tools open PNG natively. WebP support is still inconsistent in many editing environments.
- Universal sharing. PNG opens anywhere — email clients, Slack, Notion, every operating system. WebP may not preview correctly in older environments.
- E-commerce uploads. Amazon, Shopify, and Etsy all accept PNG. WebP is not always accepted as a product image upload format.
- Master files. Keep your source assets as PNGs. They are lossless, universally supported, and safe to re-export to any format later.
When WebP wins
- Web page performance. WebP files are typically 25–35% smaller than equivalent PNGs. For high-traffic websites, this directly improves Core Web Vitals scores and page load speed.
- Transparent web assets. If you need a transparent image delivered on a modern web page, WebP gives you transparency with smaller file sizes than PNG.
- Animated images. WebP supports animation with better compression than GIF, making it the better choice for simple animations in modern browsers.
The recommended workflow
The practical approach: create and edit in PNG, deliver in WebP.
Use PNG as your working format for editing, sharing, and uploading to platforms. When you are optimizing images for your website or web app, convert the PNG to WebP as the final delivery format. You get the best of both: a universal master file and fast web delivery.
Next.js and most modern frameworks can automatically serve WebP via the <Image /> component, so you may not even need to manually convert if you are already using a framework.
