About WebP
WebP is a modern image format developed by Google that supports both lossy and lossless compression, transparency, and animation. That flexibility makes WebP suitable for photos, graphics, and web delivery.
WebP files are often smaller than JPG or PNG at similar visual quality, which can help pages load faster and use less bandwidth.
Fun fact: WebP was first announced by Google in 2010 and is now supported by the vast majority of modern web browsers.
Why Convert PNG to WebP?
Converting PNG to WebP can significantly reduce file size while keeping strong visual quality. WebP supports transparency and is well suited to modern websites where performance matters.
At high quality settings, WebP can look very close to the original PNG, but some fine detail may still change during conversion. If you need maximum compatibility with older software or systems, PNG may still be the safer choice.
How to Convert PNG to WebP
Select your PNG files, open Settings to adjust quality if needed, and click Convert. Your WebP download will be ready in seconds.
