Why convert PNG to WebP for a website?

WebP is broadly supported by browsers and site builders. Whether it is smaller than the PNG depends on the image, so compare the file size shown with the result and lower the quality where the format allows it if page weight matters.

Will the WebP look the same on my site?

For most images the difference is invisible at web sizes. Use the quality control to balance sharpness against file size.

Is this PNG-to-WebP converter free?

Yes — convert and download without creating an account. Your upload is auto-deleted after conversion.

Can I adjust the WebP output quality?

Yes. Review the converted WebP result and adjust quality when that format supports it. Keep a higher setting for detail, or lower it when file size matters more.

PNG to WebP for websites: smaller files that keep transparency

Logos, icons, product cut-outs and interface screenshots are usually PNG because they need sharp edges or a transparent background. WebP keeps both. The converter does not fill transparent pixels for WebP, so a cut-out still floats over your page, and the transparency preview in Settings switches between a checkered grid and a plain website view so you can inspect the edges.

Pick the mode by content. For flat graphics, logos and text, turn on Lossless mode; it reproduces every pixel and is often still lighter than the PNG. For photos or product shots with soft shadows, leave Lossless off and set quality around 75 to 85, which keeps the transparent areas and usually cuts the size much further.

Then check the numbers: Settings shows the result's size in KB once it is ready. Oversized artwork wastes bandwidth in any format, so resize to the size your layout shows first. If a platform rejects WebP uploads, PNG to JPG is the fallback, at the cost of the transparent background.
