Why convert PNG to WebP?
PNG is a lossless format — great for quality, terrible for file size. WebP gives you:
- 25–35% smaller files than PNG at comparable quality
- Full transparency support (like PNG)
- Faster page loads — critical for SEO and Core Web Vitals
- Universal browser support (Chrome, Firefox, Safari, Edge — all since 2020)
When to keep PNG instead
- Images that must preserve every pixel exactly (screenshots, pixel art)
- Compatibility with very old software (pre-2020)
- When you're converting to WebP and then back — avoid double compression
Frequently asked questions
Does WebP support transparency like PNG?
Yes. WebP supports full alpha transparency. Converting a PNG with a transparent background to WebP preserves the transparency.
Will my PNG lose quality when converted to WebP?
At 80% quality or above, the difference is virtually invisible. For icons and UI elements, use 90%+ to keep everything pixel-perfect.
Are my PNG files uploaded to a server?
No. Conversion is 100% client-side — your files never leave your device.
Can I convert multiple PNGs at once?
Yes — drop as many as you like. Multiple files are bundled into a ZIP download.
