</iframe>WWebP already offers excellent compression, but there is often room to reduce file size further without visible quality loss. WebP compression works by re-encoding the image at a lower quality setting — typically around 72% — which removes data that the human eye cannot easily perceive. The result looks nearly identical to the original but is significantly smaller.
This is especially valuable for web delivery: smaller WebP files mean faster page loads, lower bandwidth costs, and better Core Web Vitals scores. For most photographic content, compressing to 72% quality produces files that are 30-50% smaller with no noticeable degradation. For graphics with sharp edges (text, logos), the artifacts may be more visible at aggressive settings.
Unlike server-based compressors that upload your images and add watermarks or queue delays, this tool runs entirely in your browser. Your WebP files are decoded and re-encoded locally using the Canvas API. No data leaves your device, there is no file count limit, and there is no signup wall. Batch compression is supported.

No — this tool uses lossy compression at 72% quality. However, the quality reduction is tuned to be visually imperceptible for most photographic content. For lossless output, convert to PNG instead.
Typical WebP files compress 30-50% smaller with no visible quality loss. Images with fine detail (text, screenshots) may show more artifacts at aggressive settings.
WebP encoding requires Chrome, Firefox, or Safari 16+. If your browser cannot encode WebP, the tool will display a clear error message.
