Why PNG to WebP?
PNG is great for images with transparency, but the files can get big—especially for detailed graphics or photos with alpha channels. WebP supports transparency too, but with significantly better compression.
For typical PNGs, WebP produces files 26% smaller on average. For photos with transparency (like product images on transparent backgrounds), the savings can be even higher because WebP's lossy compression handles photographic content better than PNG's lossless approach.
The key advantage: WebP lets you choose between lossy and lossless compression. Use lossless for pixel-perfect graphics, lossy for photos where you want smaller files without visible quality loss.

Frequently Asked Questions
Yes. WebP fully supports alpha channel transparency. Your transparent backgrounds, soft edges, and semi-transparent effects all transfer perfectly.
For photos or images where slight compression artifacts won't matter: lossy. For pixel-art, screenshots, or graphics where every pixel matters: lossless. When in doubt, try lossy first—you usually can't tell the difference.
Varies by image. Graphics with solid colors: 20-30% smaller. Photos with transparency: 30-50% smaller. Complex PNGs with lots of colors: 25-35% smaller. The lossy option gives better compression than lossless.
PNG works everywhere, but it's inefficient for web use. Larger files mean slower page loads, which hurts user experience and SEO. WebP gives you the same quality at smaller sizes—there's no good reason not to use it in 2024+.
