🖼️ WebP vs 📷 PNG
WebP vs PNG: file size, quality, transparency, browser support, and when to use each. Includes a side-by-side comparison table and free online converters.
Use WebP for web images (product photos, hero images, thumbnails) to get 25–35% smaller files with equal or better visual quality. Use PNG when you need pixel-perfect lossless quality, wide legacy support, or are working with logos, screenshots, and graphics with flat colours.

Frequently Asked Questions
Is WebP better than PNG?
For web use, yes — WebP typically produces files 25–35% smaller than PNG at comparable quality. However, PNG remains the better choice for logos, line art, and images that require pixel-perfect lossless quality without any compression artefacts.
Does WebP support transparency?
Yes. WebP supports alpha channel transparency, just like PNG. You can convert a transparent PNG to WebP without losing the transparency layer.
Can I use WebP on all browsers?
WebP is supported in all modern browsers: Chrome, Firefox, Edge, and Safari 14+ (released 2020). If you need to support very old browsers (IE 11, old Safari), PNG is safer. For most websites in 2026, WebP is fine.
