PNG to WebP conversion is particularly powerful because WebP supports transparency just like PNG — but at significantly smaller file sizes. If you have PNG files with transparent backgrounds (logos, icons, UI elements), converting to WebP can reduce file sizes by 25–35% without any visual difference and without losing transparency. This makes WebP the ideal replacement for PNG on modern websites. Switch & Shrink converts your PNG files to WebP while preserving alpha channel transparency. You can use our lossless WebP mode for pixel-perfect conversion with zero quality loss, or our standard mode for even smaller files with imperceptible quality difference. All major browsers support WebP, so you can safely use these files on any modern website.

Frequently Asked Questions

Does WebP preserve PNG transparency?

Yes. WebP supports alpha channel transparency just like PNG. Your transparent backgrounds will be preserved in the WebP output.

Should I use lossless or lossy WebP for my PNGs?

For logos, icons, and graphics where every pixel matters, use lossless WebP (100% quality). For photos saved as PNG, lossy WebP (85–90% quality) will give much smaller files with imperceptible quality difference.

Is WebP supported everywhere?

All major browsers support WebP: Chrome, Firefox, Safari (14+), Edge, and Opera. It covers over 97% of web users.
