Compress PNG to WebP: Convert and Optimize Images for Faster Websites
PNG images are widely used on websites because they support transparency and high-quality visuals. However, PNG files can be much larger than necessary, which can slow down your website and impact performance.
One of the easiest ways to reduce image file size is to convert PNG images to WebP.
In this guide, you’ll learn how to convert PNG to WebP and why switching formats can significantly improve website performance.
How can I compress images from PNG to WebP? You can simply upload your PNG file to a WebP optimizer, which will automatically convert and compress the image. Then download the optimized file for use on your website – reducing file size while maintaining visual quality.
Why convert PNG to WebP?
If you’re using PNG images on your website, you’re often serving more data than necessary. Converting PNG to “next gen” formats like WebP often helps you deliver the same visuals with smaller file sizes.
WebP achieves this through more efficient compression, often reducing image size by 30% compared to PNG at similar quality levels.
This reduction has a direct impact on performance:
- Faster page load times
- Improved Core Web Vitals by using next-gen formats
- Better mobile experience
- Lower bandwidth usage
- Stronger SEO performance
For websites with many images, switching from PNG to WebP is one of the simplest ways to improve speed without reworking your visuals.
That said, WebP is not always smaller than PNG. File size depends on the image itself. Simple graphics or already optimized PNGs can sometimes be just as small or smaller.
The advantage is that tools like Tinify automatically compare and optimize your images. You can convert to WebP and compress the PNG at the same time, and Tinify shows you which option gives the best result.
PNG vs WebP: What’s the difference?
PNG and WebP are both widely used image formats, but they serve different purposes.
| Feature | PNG | WebP |
|---|---|---|
| Compression type | Lossless only | Lossy and lossless |
| File size | Larger | Smaller |
| Transparency | Yes | Yes |
| Image quality | Perfect (no data loss) | High (optimized for web) |
| Best use cases | Logos, icons, UI elements | Most image types |
| Browser support | Universal | All modern browsers |
Since WebP supports both lossy and lossless compression, it can be used for a wide range of image types. It is designed for web performance, using efficient compression techniques to reduce file size while maintaining visual quality. If you want a deeper breakdown, see our guide on the pros and cons of WebP images.
That said, PNG is still preferred in some design workflows where exact visual precision is required. Because PNG preserves all image data, it’s ideal for design assets and graphics, but this also results in larger file sizes.
Common use cases for WebP
WebP is especially useful for:
- E-commerce product images
- Blog content and featured images
- Landing pages and marketing visuals
- Background images and hero banners
Reducing image weight in these areas improves both user experience and performance metrics.
