PNG to WebP Converter Tool

WebP is supported by all major modern browsers including Google Chrome, Firefox, Edge, Opera, and Safari (since macOS Big Sur). As of 2023, global browser support for WebP is over 95%. For older browsers that don't support WebP, you can implement fallback solutions using HTML's picture element.

You can use WebP images just like any other image format on your website. Simply reference them in your HTML with an <img> tag: <img src="image.webp" alt="Description">. For better browser compatibility, use the <picture> element to provide fallbacks: <picture><source srcset="image.webp" type="image/webp"><img src="image.jpg" alt="Description"></picture>

Lossy compression reduces file size by permanently removing some image data. This typically results in smaller files but may cause some quality reduction, though WebP's lossy compression is very efficient at maintaining visual quality. Lossless compression reduces file size without removing any image data, ensuring perfect quality but resulting in larger files than lossy compression. For most web use cases, lossy compression with a high quality setting (70-80%) offers the best balance of quality and file size.

When using lossless WebP conversion, there is no quality loss at all compared to the original PNG. The image data is preserved exactly, just stored more efficiently. When using lossy conversion, there may be some quality reduction, but WebP is designed to be very efficient at preserving visual quality even at high compression ratios. At high quality settings (80-100%), the difference is usually imperceptible to the human eye while still providing significant file size savings.

Yes, WebP fully supports transparency (alpha channel) like PNG. In fact, WebP can store transparency information more efficiently than PNG, resulting in smaller file sizes even for images with complex transparency. This makes WebP an excellent choice for logos, icons, and other graphics that require transparency.
