Why convert PNG to WebP?

WebP files are typically 25—35% smaller than PNG while maintaining the same visual quality and supporting transparency.

Does WebP support transparency?

Yes. WebP supports alpha transparency, so transparent areas in your PNG will be preserved in the WebP output.

Is my image uploaded to a server?

No. All conversion happens in your browser. Your files never leave your device.

Is WebP supported everywhere?

WebP is supported by all modern browsers. For maximum compatibility with older software, PNG remains the safer choice.

Does WebP support transparency like PNG?

Yes. WebP fully supports alpha channel transparency. Transparent areas in your PNG are preserved perfectly in the WebP output — both for lossless and lossy WebP modes.

Should I use lossless or lossy WebP for icons?

For icons and logos with sharp edges, lossless WebP is recommended to prevent compression artifacts around edges. For photographs or complex gradients, lossy WebP at 80%+ quality is ideal.

How much smaller is lossless WebP than PNG?

Google reports that lossless WebP is approximately 26% smaller than PNG. For lossy WebP with transparency, savings can be even greater.

Are my PNG files sent to a remote server?

No. The conversion runs locally in your browser using the Canvas API. Your PNG files are decoded in browser memory and re-encoded to WebP without being transmitted to any server.

What is PNG to WebP?

PNG to WebP is the optimal conversion for web graphics, icons, logos, and UI elements that require transparency. Unlike PNG to JPG (which destroys transparency), WebP fully supports alpha channel transparency while producing files that are significantly smaller than PNG. Google's data shows WebP is 26% smaller than PNG for lossless images. This makes it the ideal format for website graphics that need transparent backgrounds — think logos, icon sets, product cutouts, and UI overlays. The key advantage: you get WebP's compression efficiency without sacrificing a single pixel of transparency data. Our converter supports both lossy WebP (for maximum compression) and lossless WebP (for pixel-perfect output matching the original PNG quality). All conversion runs in your browser — your graphic files never leave your device.
