When to use this method

• You are publishing to a modern website and want a smaller file than PNG.
• You have a transparent PNG and wonder if WebP can keep the clear background at a smaller size.
• A CMS or CDN offers WebP and you need a simple yes/no for your asset.

Step-by-step

1. Check where the image will be used. If the destination only lists PNG or JPG, keep or convert to those formats.
2. If the audience uses modern browsers and size matters, plan on WebP.
3. Keep PNG when maximum compatibility matters more than bytes (some email tools, older software, or strict portals).
4. For a transparent graphic, convert PNG to WebP and confirm the preview still shows a clear background.
5. For a photo that is currently PNG, prefer WebP or JPG instead of a huge PNG.
6. Convert with PNG to WebP (or WebP to PNG when you need compatibility), download, then publish.

Tips

• WebP can be lossy or lossless. Smaller web photos usually use lossy WebP; UI graphics can use lossless WebP when you need crisp edges.
• Always preview transparency after converting a cut-out product image.
• Offer a PNG or JPG fallback only if you know some users cannot open WebP.
• If the file is still too large after converting to WebP, use Compress Image or a size-target tool.

Limitations

• Very old browsers and some desktop apps do not open WebP.
• Konvert tools process one image at a time in the browser.
• This guide is about still images. Animated WebP is a separate, less common workflow.

Common mistakes

• Replacing every PNG with WebP on a site that must support very old browsers — without a fallback.
• Keeping photographic PNGs on a page when WebP or JPG would load much faster.
• Converting to WebP for a government or bank form that only accepts JPG/PNG.
• Assuming WebP always looks identical — check edges and fine text at 100% zoom.
